一种数据传输的方法、网络芯片以及通信系统A data transmission method, network chip and communication system

技术领域technical field

本申请涉及通信领域，尤其涉及一种数据传输的方法、网络芯片以及通信系统。The present application relates to the communication field, in particular to a data transmission method, a network chip and a communication system.

背景技术Background technique

前向纠错(forward error correction，FEC)编码是一种在通信系统中控制传输错误的技术，通过在发送数据中加入额外的信息进行错误恢复，以降低误码率。随着串行数据速率的不断提升，已经接近每条通道56G比特/秒，信噪比对高速信号的影响正在不断提高，因此需要采用FEC技术对传输数据进行纠错，以降低误码率。Forward error correction (forward error correction, FEC) coding is a technology to control transmission errors in a communication system, by adding additional information to the transmitted data for error recovery to reduce the bit error rate. With the continuous improvement of the serial data rate, it is close to 56Gbit/s per channel, and the impact of the signal-to-noise ratio on high-speed signals is constantly increasing. Therefore, it is necessary to use FEC technology to correct errors in the transmitted data to reduce the bit error rate.

现有方案中，一个编码器对应一个业务接口，该编码器对接收到的该业务接口的数据进行编码。以以太网实现FEC编码的方式为例，在接收到以从太网接口传输的数据后，将该数据进行扰码、重组、插入预置标识等等之后，输入到编码器中，以输出码流数据，该码流数据将通过以太网的物理介质访问(physical media Access，PMA)发送至对应的接收端中。In the existing solution, one encoder corresponds to one service interface, and the encoder encodes the received data of the service interface. Taking the way of Ethernet to realize FEC encoding as an example, after receiving the data transmitted from the Ethernet interface, the data is scrambled, reorganized, inserted into the preset logo, etc., and then input into the encoder to output the code Stream data, the code stream data will be sent to the corresponding receiving end through physical media access (PMA) of Ethernet.

上述方案中，业务接口与编码器是一一对应的。若有多个业务接口，则需要与该多个业务接口一一对应的编码器，容易产生资源浪费。例如，一个里德所罗门前向纠错码(Reed Solomon forward error correction，RS-FEC)编码器仅能支持单一的以太网端口，即RS-FEC编码器仅能处理一个业务接口传输的数据，若有多个业务接口，则需要多个一一对应的RS-FEC编码器，容易造成资源浪费。In the above solution, there is a one-to-one correspondence between the service interface and the encoder. If there are multiple service interfaces, encoders corresponding to the multiple service interfaces are required, which is prone to waste of resources. For example, a Reed Solomon forward error correction code (Reed Solomon forward error correction, RS-FEC) encoder can only support a single Ethernet port, that is, the RS-FEC encoder can only process data transmitted by one service interface, if If there are multiple service interfaces, multiple one-to-one corresponding RS-FEC encoders are required, which is likely to cause waste of resources.

具体地，该多个业务接口可以包括不同业务类型的业务接口，例如，该多个业务接口可以包括一个或多个的不同业务类型的接口，该不同业务类型可以是以太网接口、FlexE接口、FlexO接口或Interlaken接口等。并且，根据业务接口的业务类型的不同，获取对应的传输数据的过程也不相同，可以是直接从业务接口中接收传输数据，也可以是对业务接口发送的数据进行进一步处理后得到传输数据，更具体地步骤在以下实施例中将做进一步说明，此处不作赘述。Specifically, the multiple service interfaces may include service interfaces of different service types, for example, the multiple service interfaces may include one or more interfaces of different service types, and the different service types may be Ethernet interfaces, FlexE interfaces, FlexO interface or Interlaken interface, etc. In addition, depending on the business type of the service interface, the process of obtaining the corresponding transmission data is also different.

因此，本申请实施例中，可以接入相同或不同业务类型的多个业务接口，并获取该多个业务接口的数据，以便后续进行编码处理，实现多个业务接口共用编码器，提高编码器的利用率。Therefore, in the embodiment of the present application, multiple service interfaces of the same or different service types can be accessed, and the data of the multiple service interfaces can be obtained for subsequent encoding processing, so that multiple service interfaces can share an encoder and improve the efficiency of the encoder. utilization rate.

202、通过信道编码器在第一传输时隙对第一传输数据进行编码，以得到第一码流数据，以及在第二传输时隙对第二传输数据进行编码，以得到第二码流数据。202. Use a channel encoder to encode the first transmission data in the first transmission time slot to obtain the first code stream data, and encode the second transmission data in the second transmission time slot to obtain the second code stream data .

在接收到多个业务接口对应的多组传输数据后，可以确定每组传输数据对应的传输时隙。并在每组传输数据对应的时隙，通过同一信道编码器，对每组传输数据进行编码，得到每组数据对应的码流数据。以第一传输数据与第二传输数据为例，以确定第一传输数据的第一传输时隙，以及第二传输数据的第二传输时隙，第一传输数据为该多组传输数据中的任意一组传输数据，第二传输数据为该多组数据中与第一传输数据不同的任意一组传输数据，第一传输时隙为与该第一传输数据对应的时隙，第二传输时隙为第二传输数据对应的时隙。并且，第一传输时隙与第二传输时隙不同。在第一传输时隙将第一传输数据输入信道编码器，输出第一码流数据，并且在第二传输时隙可以通过同一信道编码器，对第二传输数据进行信道编码，输出第二码流数据。After receiving multiple sets of transmission data corresponding to multiple service interfaces, the transmission time slot corresponding to each set of transmission data can be determined. And in the time slot corresponding to each group of transmission data, the same channel encoder is used to encode each group of transmission data to obtain the code stream data corresponding to each group of data. Taking the first transmission data and the second transmission data as an example, to determine the first transmission time slot of the first transmission data and the second transmission time slot of the second transmission data, the first transmission data is one of the multiple sets of transmission data Any set of transmission data, the second transmission data is any set of transmission data different from the first transmission data among the multiple sets of data, the first transmission time slot is the time slot corresponding to the first transmission data, and the second transmission time The slot is a time slot corresponding to the second transmission data. Also, the first transmission slot is different from the second transmission slot. In the first transmission time slot, the first transmission data is input into the channel coder, and the first code stream data is output, and in the second transmission time slot, the second transmission data can be channel coded by the same channel coder, and the second code is output stream data.

获取到的每组传输数据，都可以在对应的传输数据进行编码，得到对应的码流数据。例如，若获取到i组传输数据，i为大于等于2的整数，在获取到该i组传输数据中每组传输数据一一对应的传输时隙后，在每组传输数据对应的传输时隙对每组传输数据进行编码，得到每组传输数据对应的码流数据。Each set of acquired transmission data can be encoded on the corresponding transmission data to obtain the corresponding code stream data. For example, if i group of transmission data is obtained, i is an integer greater than or equal to 2, after obtaining the one-to-one transmission time slot corresponding to each group of transmission data in the i group of transmission data, in the transmission time slot corresponding to each group of transmission data Each group of transmission data is encoded to obtain code stream data corresponding to each group of transmission data.

其中，可选的，对第一传输数据进行编码的方式可以是RS-FEC编码，即该信道编码器可以是RS-FEC编码器。例如，可以将该第一传输数据输入到RS-FEC编码器，以进行RS-FEC编码，得到RS-FEC编码后的第一码流数据。除了RS-FEC编码，该信道编码方式也可以包括常用的FEC编码方式，或者下一代网络中将使用到的编码方式等等。Wherein, optionally, the manner of encoding the first transmission data may be RS-FEC encoding, that is, the channel encoder may be an RS-FEC encoder. For example, the first transmission data may be input to an RS-FEC encoder to perform RS-FEC encoding to obtain RS-FEC-encoded first code stream data. In addition to RS-FEC coding, the channel coding method may also include a commonly used FEC coding method, or a coding method to be used in the next generation network, and the like.

示例性地，具体的RS-FEC编码过程可以是，根据预置的生成多项式对第一传输数据进行计算，计算出第一传输数据的校验多项式，然后将第一传输数据与校验多项式进行组合，得到第一码流数据。Exemplarily, the specific RS-FEC encoding process may be to calculate the first transmission data according to the preset generator polynomial, calculate the check polynomial of the first transmission data, and then perform the first transmission data and the check polynomial combined to obtain the first code stream data.

其中，可选地，在本申请实施例中，每组传输数据对应的传输时隙可以是预置的，也可以是在获取到传输数据后实时分配的。具体地，若传输时隙为预置的，则在获取该多组传输数据之前，可以为每个接入的业务接口分配对应的时隙，并可以保存在数据库中。并且，更具体地，为每个接入的业务接口分配的时隙还可以是按照固定周期分配的，例如，一个周期可以包括N个时隙，然后将该N个时隙分别分配给接入的业务接口，N＞＝1。在获取到业务接口对应的传输数据后，可以根据该业务接口从数据库中查找该传输数据的传输时隙。若传输时隙为实时分配的，在获取该多组传输数据之后，可以根据业务接口的业务类型进行时隙分配，也可以按照获取顺序进行时隙分配，还可以按照传输数据的优先级进行时隙分配等等，具体可以根据实际应用场景进行调整。Wherein, optionally, in the embodiment of the present application, the transmission time slot corresponding to each group of transmission data may be preset, or may be allocated in real time after the transmission data is acquired. Specifically, if the transmission time slot is preset, before acquiring the multiple sets of transmission data, a corresponding time slot may be allocated to each accessed service interface and stored in the database. And, more specifically, the time slots allocated to each accessed service interface can also be allocated according to a fixed cycle, for example, a cycle can include N time slots, and then the N time slots are allocated to the access service interface, N>=1. After obtaining the transmission data corresponding to the service interface, the transmission time slot of the transmission data can be searched from the database according to the service interface. If the transmission time slots are allocated in real time, after obtaining the multiple sets of transmission data, the time slots can be allocated according to the service type of the service interface, the time slots can also be allocated according to the order of acquisition, and the time slots can also be allocated according to the priority of the transmission data. slot allocation, etc., which can be adjusted according to actual application scenarios.

此外，可选的，在获取到每组传输数据后，也可以对每组数据进行其他处理，例如，对传输数据进行分组、插入预置的标识数据等等，之后再进行编码。In addition, optionally, after each set of transmission data is acquired, other processing may be performed on each set of data, for example, grouping the transmission data, inserting preset identification data, etc., and then encoding.

203、在第一传输时隙，将第一码流数据按照预置分发规则分发至对应的PMA，以及在第二传输时隙，将第二码流数据按照预置分发规则分发至对应的PMA。203. In the first transmission time slot, distribute the first code stream data to the corresponding PMA according to the preset distribution rule, and in the second transmission time slot, distribute the second code stream data to the corresponding PMA according to the preset distribution rule .

在对每组传输数据完成RS-FEC编码，得到每组传输数据对应的码流数据后，根据每组码流数据对应的传输时隙将第一码流数据按照预置的分发规则分发至PMA，并将第二码流数据按照预置的规则分发至PMA，由PMA确定码流数据的传输通道，并发送至PMD子层，通过PMD子层确定传输通道，将第一码流数据传输至第一码流数据对应的接收端，并将第二码流数据传输至第二码流数据对应的接收端。After completing RS-FEC encoding for each group of transmission data and obtaining the code stream data corresponding to each group of transmission data, the first code stream data is distributed to the PMA according to the preset distribution rules according to the transmission time slot corresponding to each group of code stream data , and distribute the second code stream data to the PMA according to the preset rules, the PMA determines the transmission channel of the code stream data, and sends it to the PMD sublayer, determines the transmission channel through the PMD sublayer, and transmits the first code stream data to the receiving end corresponding to the first code stream data, and transmit the second code stream data to the receiving end corresponding to the second code stream data.

该预置的分发规则可以是，确定第一传输数据对应的业务接口对应的传输通道，并将第一码流数据分配至对应的传输通道中进行发送。以及确定第二传输数据对应的业务接口对应的传输通道，并将第二码流数据分配至对应的传输通道中进行发送。The preset distribution rule may be to determine the transmission channel corresponding to the service interface corresponding to the first transmission data, and allocate the first code stream data to the corresponding transmission channel for transmission. And determining the transmission channel corresponding to the service interface corresponding to the second transmission data, and assigning the second code stream data to the corresponding transmission channel for transmission.

需要说明的是，本申请实施例中的第一传输数据与第二传输数据仅仅是示例性说明，实际可以接收多组传输数据，为每组传输数据确定对应的传输时隙。并在每组传输数据对应的传输数据使用同一信道编码器进行信道编码，使多个业务接口可以共用一个编码器。It should be noted that the first transmission data and the second transmission data in the embodiment of the present application are only illustrative, and multiple sets of transmission data may be received actually, and a corresponding transmission time slot may be determined for each set of transmission data. And the transmission data corresponding to each group of transmission data is channel coded by using the same channel coder, so that multiple service interfaces can share one coder.

在本申请实施例中，PCS子层可以接入多个业务接口，该多个业务接口可以是业务类型相同的业务接口，也可以是业务类型不同的业务接口。并获取该多个业务接口对应的传输数据，包括直接接收业务接口发送的数据，或对接收到的业务接口发送的数据处理后的数据。并确定该多个业务接口对应的传输数据的传输时隙，根据传输时隙对传输数据进行编码以及分发等，完成对多个业务接口对应的传输数据的处理。因此，本申请实施例提供的数据传输方法可以通过一个RS-FEC编码器，通过分配时隙的方式，对多个业务接口的传输数据进行RS-FEC编码，以实现RS-FEC资源的高效利用。In the embodiment of the present application, the PCS sublayer may access multiple service interfaces, and the multiple service interfaces may be service interfaces of the same service type, or service interfaces of different service types. And acquire the transmission data corresponding to the multiple service interfaces, including directly receiving the data sent by the service interfaces, or the data after processing the received data sent by the service interfaces. And determine the transmission time slots of the transmission data corresponding to the multiple service interfaces, encode and distribute the transmission data according to the transmission time slots, and complete the processing of the transmission data corresponding to the multiple service interfaces. Therefore, the data transmission method provided by the embodiment of the present application can use an RS-FEC encoder to perform RS-FEC encoding on the transmission data of multiple service interfaces by allocating time slots, so as to realize efficient utilization of RS-FEC resources .

前述对本申请提供的数据传输方法的发送流程进行了说明，下面对本申请提供的数据传输方法的接收流程进行详细说明，请参阅图3，本申请实施例提供的数据传输方法的另一种流程示意图，可以包括：The foregoing describes the sending process of the data transmission method provided by this application, and the following describes the receiving process of the data transmission method provided by this application in detail. Please refer to Figure 3, another schematic flow diagram of the data transmission method provided by the embodiment of this application , which can include:

301、获取多组码流数据。301. Acquire multiple sets of code stream data.

首先获取多组码流数据，该多组码流数据可以与多个业务接口对应，当与多个业务接口对应时，该多个业务接口的业务类型可以相同，也可以不同。First, multiple sets of code stream data are obtained. The multiple sets of code stream data may correspond to multiple service interfaces. When corresponding to multiple service interfaces, the service types of the multiple service interfaces may be the same or different.

该多组码流数据可以是直接从PMA子层接收到的数据，也可以是对从PMA子层接收到的数据进行处理后得到数据，例如，在获取该多组码流数据之前，还可以包括对接收的数据进行解调、偏斜补偿等步骤，以得到该多组码流数据，具体此处不再一一阐述。The multiple sets of code stream data may be data received directly from the PMA sublayer, or data obtained after processing the data received from the PMA sublayer. For example, before obtaining the multiple sets of code stream data, you may also Steps such as demodulating and skew compensating the received data are included to obtain the multiple sets of code stream data, which will not be elaborated here one by one.

302、通过解码器在第一传输时隙对第一码流数据进行解码，得到第一传输数据，在第二传输时隙对第二码流数据进行解码，得到第二传输数据。302. Use a decoder to decode the first code stream data in a first transmission time slot to obtain first transmission data, and decode the second code stream data in a second transmission time slot to obtain second transmission data.

在获取到多组码流数据后，可以确定每组码流数据对应的传输时隙。并且在确定每组码流数据的传输时隙后，使用同一编码器在每组码流数据对应的传输时隙对每组码流数据进行编码。After acquiring multiple sets of code stream data, the transmission time slot corresponding to each set of code stream data can be determined. And after the transmission time slot of each group of code stream data is determined, the same encoder is used to encode each group of code stream data in the transmission time slot corresponding to each group of code stream data.

以第一码流数据与第二码流数据为例，可以确定第一码流数据对应的第一传输时隙，以及第二码流数据对应的第二传输时隙。第一码流数据为该多组码流数据中任意一组码流数据，第二码流数据为该多组码流数据中除第一码流数据之外的任意一组码流数据。第一传输时隙为该第一码流数据对应的传输时隙，第二传输时隙为第二码流数据对应的传输时隙。本申请实施例仅以该多组码流数据中的第一码流数据与第二码流数据进行示例性说明。Taking the first code stream data and the second code stream data as an example, the first transmission time slot corresponding to the first code stream data and the second transmission time slot corresponding to the second code stream data may be determined. The first code stream data is any set of code stream data in the multiple sets of code stream data, and the second code stream data is any set of code stream data in the multiple sets of code stream data except the first code stream data. The first transmission time slot is a transmission time slot corresponding to the first code stream data, and the second transmission time slot is a transmission time slot corresponding to the second code stream data. The embodiment of the present application is only illustrated by using the first code stream data and the second code stream data in the multiple sets of code stream data.

在确定第一码流数据对应的第一传输时隙后，使用解码器在第一传输时隙对第一码流数据进行解码，以得到第一传输时隙。在确定第二码流数据对应的第二传输时隙后，使用同一解码器在第二传输时隙对第二码流数据进行解码，得到第二传输数据。After the first transmission time slot corresponding to the first code stream data is determined, the decoder is used to decode the first code stream data in the first transmission time slot to obtain the first transmission time slot. After determining the second transmission time slot corresponding to the second code stream data, the same decoder is used to decode the second code stream data in the second transmission time slot to obtain second transmission data.

具体地，发送端侧在发送数据之前，对数据进行编码，因此，在接收到第一码流数据后，可以对第一码流数据进行解码，以完成对第一码流数据的纠错，得到第一解码数据。Specifically, the sending end side encodes the data before sending the data, therefore, after receiving the first code stream data, it can decode the first code stream data to complete the error correction of the first code stream data, Obtain the first decoded data.

可选的，具体的解码方式可以是针对信道编码进行的解码，例如，若网络芯片执行的是RS-FEC编码，那么，本申请实施例中可以对第一码流数据进行RS-FEC解码。Optionally, the specific decoding method may be decoding for channel coding. For example, if the network chip performs RS-FEC coding, then RS-FEC decoding may be performed on the first code stream data in this embodiment of the present application.

在本申请的一种可选实施方式中，在对第一码流数据进行解码之前，若第一码流数据分为多个数据包由多个传输通道并行传输，可能因每二个传输通道的时延不同，导致获取到的第一码流数据错位。因此，还可以对该多个数据包进行校正。具体地，每个数据包中可能包括插入的对齐标识(Align Marker，AM)，可以根据对齐标识，对该多个数据包进行重组，可以避免重组后的第一码流数据出现数据错误。In an optional implementation manner of the present application, before decoding the first code stream data, if the first code stream data is divided into multiple data packets and transmitted in parallel by multiple transmission channels, it may be possible that every second transmission channel The time delays are different, resulting in misalignment of the obtained first code stream data. Therefore, corrections can also be performed on the plurality of data packets. Specifically, each data packet may include an inserted alignment mark (Align Marker, AM), and the plurality of data packets can be reassembled according to the alignment mark, which can avoid data errors in the reassembled first code stream data.

在本申请的一种可选实施方式中，每组码流数据的传输时隙可以是在接收到每组码流数据后实时分配的，在接收到每组码流数据后，可以为每组码流数据分配传输时隙，在每组码流数据对应的传输时隙对每组码流数据进行处理，可以避免同时处理多组码流数据，造成网络芯片负载过大或数据错误等。具体地，可以是按照接收顺序为每组码流数据分配传输时隙，也可以是按照码流数据的优先级分配传输时隙等，可以根据实际应用场景进行调整，此处不作限定。In an optional implementation of the present application, the transmission time slot of each group of code stream data can be allocated in real time after receiving each group of code stream data, after receiving each group of code stream data, it can be allocated for each group The code stream data is assigned transmission time slots, and each group of code stream data is processed in the transmission time slot corresponding to each group of code stream data, which can avoid processing multiple sets of code stream data at the same time, causing excessive load on the network chip or data errors. Specifically, transmission time slots may be assigned to each group of code stream data according to the receiving order, or transmission time slots may be allocated according to the priority of the code stream data, etc., which may be adjusted according to actual application scenarios, and are not limited here.

在本申请的一种可选实施方式中，每组码流数据的传输时隙还可以是在接收每组码流数据之前，按照预置方式为每个业务接口分配传输时隙的。例如，可以将一个周期平均分为多个时隙，每个业务接口对应的时隙大小相同，也可以按照每个业务接口的数据量来分配时隙，数据量大的业务接口，所分配的时隙也可以较大等等。又例如，若网络芯片接入有N个业务接口，N＞＝1，该N个业务接口可以是相同业务类型的接口，也可以是不同业务类型的接口，还可以包括多个相同业务类型以及多个不同业务类型的接口。在接收每个业务接口对应的码流数据之前，为每个业务接口分配预置的传输时隙，在接收到码流数据后，可以首先判断该码流数据对应的业务接口，然后根据对应的业务接口查询该码流数据的传输时隙。In an optional implementation manner of the present application, the transmission time slot for each set of code stream data may also be allocated to each service interface in a preset manner before receiving each set of code stream data. For example, a cycle can be divided into multiple time slots on average, and the time slots corresponding to each service interface have the same size, or the time slots can be allocated according to the data volume of each service interface. The time slots can also be larger and so on. For another example, if there are N service interfaces connected to the network chip, N>=1, the N service interfaces can be interfaces of the same service type, or interfaces of different service types, and can also include multiple same service types and Multiple interfaces of different business types. Before receiving the code stream data corresponding to each service interface, assign a preset transmission time slot for each service interface. After receiving the code stream data, you can first determine the service interface corresponding to the code stream data, and then according to the corresponding The service interface queries the transmission time slot of the stream data.

303、将第一传输数据传输至对应的第一业务接口，将第二传输数据传输至对应的第二业务接口。303. Transmit the first transmission data to a corresponding first service interface, and transmit the second transmission data to a corresponding second service interface.

在对每组码流数据分别在对应的时隙进行解码，得到对应的传输数据后之后，可以分别将每组传输数据传输至对应的业务接口。以第二传输数据与第二传输数据为例，在对第一码流数据进行解码得到第一传输数据之后，将第一传输数据分发至对应的第一业务接口。在使用同一解码器对第二码流数据进行解码得到第二传输数据之后，将第二传输数据分发至对应的第二业务接口。After decoding each group of code stream data in a corresponding time slot to obtain corresponding transmission data, each group of transmission data can be transmitted to a corresponding service interface. Taking the second transmission data and the second transmission data as an example, after the first code stream data is decoded to obtain the first transmission data, the first transmission data is distributed to the corresponding first service interface. After the second code stream data is decoded by the same decoder to obtain the second transmission data, the second transmission data is distributed to the corresponding second service interface.

需要说明的是，本申请实施例中，在得到每组传输数据后，可以根据业务接口的业务类型，对每组传输数据进行传输。可以是直接发送至对应的业务接口，也可以是对每组传输数据进行进一步解码、解扰等处理之后，再发送至对应的业务接口。例如，若第一传输数据对应的业务接口为FlexE接口或以太网接口，则对得到的第一传输数据进行进一步解扰并解码之后，再发送至该FlexE接口或以太网接口。若第一传输数据对应的业务接口为FlexO接口，则直接将该第一传输数据发送至该FlexO接口。若该业务接口为Interlaken接口，则对第一传输数据进行解码并解扰后，发送至该Interlaken接口。It should be noted that, in the embodiment of the present application, after each group of transmission data is obtained, each group of transmission data may be transmitted according to the service type of the service interface. It may be directly sent to the corresponding service interface, or it may be sent to the corresponding service interface after further processing such as decoding and descrambling for each group of transmission data. For example, if the service interface corresponding to the first transmission data is a FlexE interface or an Ethernet interface, the obtained first transmission data is further descrambled and decoded, and then sent to the FlexE interface or the Ethernet interface. If the service interface corresponding to the first transmission data is a FlexO interface, the first transmission data is directly sent to the FlexO interface. If the service interface is an Interlaken interface, the first transmission data is decoded and descrambled, and then sent to the Interlaken interface.

还需要说明的是，本申请实施例中的步骤303为可选步骤。It should also be noted thatstep 303 in the embodiment of the present application is an optional step.

更进一步地，下面对本申请实施例提供的数据传输方法的发送与接收流程进行更详细的示例性说明。请参阅图4，本申请实施例提供的数据传输方法的另一种实施例示意图，可以包括发送流程与接收流程。发送流程可以理解为编码流程，接收流程可以理解为解码流程，下面结合编码流程与解码流程，以RS-FEC编码与解码的方式为例，进行更进一步地详细说明。Furthermore, a more detailed exemplary description will be given below of the sending and receiving process of the data transmission method provided by the embodiment of the present application. Please refer to FIG. 4 , which is a schematic diagram of another embodiment of the data transmission method provided by the embodiment of the present application, which may include a sending process and a receiving process. The sending process can be understood as an encoding process, and the receiving process can be understood as a decoding process. The following combines the encoding process and the decoding process, taking RS-FEC encoding and decoding as an example to describe in further detail.

其中，本申请实施例中的业务接口可以包括不同类型的多个接口，下面以4种接口为例，可以包括：以太网接口、FlexE接口、FlexO接口以及Interlaken接口，进行示例性说明。示例性地，每种业务类型的接口可以有一个或者多个，例如，Interlaken接口可以有一个或者多个，图4中仅以2个为例进行说明。Wherein, the service interface in the embodiment of the present application may include multiple interfaces of different types. The following four types of interfaces are taken as examples, which may include: Ethernet interface, FlexE interface, FlexO interface and Interlaken interface, for exemplary illustration. Exemplarily, there may be one or more interfaces for each service type, for example, there may be one or more Interlaken interfaces, and only two are used as an example for illustration in FIG. 4 .

首先，对PCS子层发送数据的步骤进行说明。其中，PCS子层可以接收多个业务接口发送的数据，该多个业务接口可以包括：以太网接口、FlexE接口、FlexO接口或Interlaken接口等等。通常，对于接收到的FlexO接口传输的数据，可以直接作为传输数据进行时分复用(Time Division Multiplexing，TDM)调度，而对于以太网接口、FlexE接口以及Interlaken接口传输的数据，则需要进行处理，得到对应的传输数据之后，才进行TDM调度。First, the steps of sending data by the PCS sublayer are described. Wherein, the PCS sublayer may receive data sent by multiple service interfaces, and the multiple service interfaces may include: an Ethernet interface, a FlexE interface, a FlexO interface, or an Interlaken interface, and the like. Usually, the received data transmitted by the FlexO interface can be directly used as transmission data for Time Division Multiplexing (TDM) scheduling, while the data transmitted by the Ethernet interface, FlexE interface and Interlaken interface need to be processed. TDM scheduling is performed only after corresponding transmission data is obtained.

业务接口可以包括一个或多个以太网接口或FlexE接口，当接收到以太网接口或FlexE接口的传输的初始码流数据时，该初始码流数据，即以太网接口的数据或FlexE接口的数据可以是以66B为单位的数据，可以对接收到的以太网接口的数据与FlexE接口的数据进行TDM调度(即步骤4011)，确定每个业务接口对应的处理时隙。其中，每个业务接口对应的处理时隙可以是预置的，即提前为每个业务接口分配的，也可以是在接收到每个业务接口发送的数据后，实时分配的。当每个业务接口对应的处理时隙为预置的，则可以在接收到每个业务接口对应的数据时，在数据库中查询每个业务接口对应的时隙，以便后续在对应的处理时隙处理每个业务接口对应的数据。若每个业务接口对应的处理时隙为实时分配的，则可以对获取到的每个业务接口对应的数据按照业务类型、获取顺序、优先级等等，进行实时分配，以得到每个业务接口对应的数据的处理时隙。因此，本申请实施例在接收到以太网接口的数据或FlexE接口的数据后，可以确定每个业务接口对应的处理时隙，进行TDM调度，对每个业务接口传输的数据进行分时处理，实现一个或多个以太网接口或FlexE接口对应的数据的处理，使一个或多个以太网接口或FlexE接口对应的数据可以共用RS-FEC编码资源，提高RS-FEC编码资源的利用率。The service interface may include one or more Ethernet interfaces or FlexE interfaces. When receiving the initial code stream data transmitted by the Ethernet interface or the FlexE interface, the initial code stream data, that is, the data of the Ethernet interface or the data of the FlexE interface The data may be in units of 66B, and TDM scheduling may be performed on the received data of the Ethernet interface and the data of the FlexE interface (that is, step 4011), and the processing time slot corresponding to each service interface is determined. Wherein, the processing time slot corresponding to each service interface may be preset, that is, allocated for each service interface in advance, or may be allocated in real time after receiving data sent by each service interface. When the processing time slot corresponding to each service interface is preset, when the data corresponding to each service interface is received, the time slot corresponding to each service interface can be queried in the database, so that the corresponding processing time slot can be processed subsequently Process the data corresponding to each business interface. If the processing time slot corresponding to each service interface is allocated in real time, then the obtained data corresponding to each service interface can be allocated in real time according to the service type, acquisition order, priority, etc., to obtain each service interface The corresponding data processing time slot. Therefore, in the embodiment of the present application, after receiving the data of the Ethernet interface or the data of the FlexE interface, the processing time slot corresponding to each service interface can be determined, TDM scheduling can be performed, and the data transmitted by each service interface can be processed in time-sharing. Realize the processing of data corresponding to one or more Ethernet interfaces or FlexE interfaces, so that the data corresponding to one or more Ethernet interfaces or FlexE interfaces can share RS-FEC encoding resources, and improve the utilization rate of RS-FEC encoding resources.

在进行66B数据的TDM调度后，确定每个业务接口对应的处理时隙后，在每个处理时隙进行对应的66B至257B转码(即步骤4012)，即对66B数据在对应的处理时隙进行转码，得到256B数据。具体地，通常接收到的业务接口发送的数据为数据流，即可以包括多个66B数据。可以将数据进行处理，包括将多个66B数据进行处理组合，得到257B数据，其中，因通常接收到的数据为66B数据的数据流，因此，将多个66B数据进行处理组合后，可以得到包括257B数据的数据流。After performing the TDM scheduling of 66B data, after determining the processing time slot corresponding to each service interface, perform corresponding 66B to 257B transcoding in each processing time slot (that is, step 4012), that is, the corresponding processing time for 66B data Slots are transcoded to obtain 256B data. Specifically, generally received data sent by the service interface is a data stream, that is, may include a plurality of 66B data. The data can be processed, including processing and combining multiple 66B data to obtain 257B data, among which, because the data usually received is a data stream of 66B data, after processing and combining multiple 66B data, it can be obtained including The data flow of 257B data.

通常，66B数据可以包括数据66B与控制66B，数据66B的比特0位为0，比特1位为1，控制66B的比特0位为1，比特1位为0。Generally, 66B data may includedata 66B andcontrol 66B,bit 0 ofdata 66B is 0,bit 1 is 1,bit 0 ofcontrol 66B is 1, andbit 1 is 0.

示例性地，将66B数据转码为257B数据的规则可以有多种，具体可以包括：Exemplarily, there may be various rules for transcoding 66B data into 257B data, which may specifically include:

1、当数据流中的66B数据都为数据66B时，将每个数据的比特0位与比特1位删除，将删除后的64B数据组成256比特的数据，并且在256比特的数据的头部添加值为1的比特位。例如，如图5所示，包括4个数据66B：tx_code_0、tx_code_1、tx_code_2以及tx_code_3。可以将4个数据66B的前2位删除，然后组成256B数据，在256数据头部增加比特1，即可得到257B数据，即tx_xcoded。1. When the 66B data in the data stream are alldata 66B, delete thebit 0 andbit 1 of each data, and form the deleted 64B data into 256-bit data, and place it at the head of the 256-bit data A bit with a value of 1 is added. For example, as shown in FIG. 5 , four pieces ofdata 66B are included: tx_code_0, tx_code_1, tx_code_2, and tx_code_3. The first 2 bits of the 4 pieces ofdata 66B can be deleted to form 256B data, andbit 1 can be added to the header of the 256 data to obtain 257B data, namely tx_xcoded.

2、当第1个66B数据为控制66B，后面3个数据为数据66B时，可以将控制66B与数据66B的比特0位与比特1位删除，并且把控制66B的比特6位至比特9位删除，组成252B数据，然后在252B数据头部添加0111表示控制66B后跟着3个数据66B，组合成256B数据，然后在256B数据头部添加比特0，得到257B数据，且比特位0表示该257B数据为带控制数据的257B数据。例如，如图6所示，包括1个数据66B以及2个控制66B：tx_code_0、tx_code_1、tx_code_2以及tx_code_3。将控制66B与数据66B的比特0位与比特1位删除，并且把控制66B的比特6位至比特9位删除，组成252B数据，然后在252B数据头部添加0111表示控制66B后包括3个数据66B，组合成256B数据，然后在256B数据头部添加比特0，得到257B数据，即tx_xcoded。2. When the first 66B data iscontrol 66B and the next three data aredata 66B, thebit 0 andbit 1 ofcontrol 66B anddata 66B can be deleted, and bit 6 to bit 9 ofcontrol 66B can be deleted Delete to form 252B data, and then add 0111 to the 252B data header to indicatecontrol 66B followed by 3data 66B to form 256B data, then addbit 0 to the 256B data header to obtain 257B data, andbit 0 indicates the 257B The data is 257B data with control data. For example, as shown in FIG. 6 , one piece ofdata 66B and two pieces ofcontrol 66B are included: tx_code_0, tx_code_1, tx_code_2, and tx_code_3.Delete bit 0 andbit 1 ofcontrol 66B anddata 66B, and delete bit 6 to bit 9 ofcontrol 66B to form 252B data, and then add 0111 to the 252B data header to indicate thatcontrol 66B includes 3data 66B, combined into 256B data, and then addbit 0 to the 256B data header to get 257B data, namely tx_xcoded.

3、当前3个数据为数据66B，后1个为控制66B时，可以将数据66B与控制66B的比特0位与比特1位删除，控制66B把比特6位到比特9位删除掉，在最前面添加4比特1111表示3个数据66B后面跟着1个控制66B，拼成1个256比特数据，然后在最前面添上比特0表示是带控制的257B。例如，如图7所示，包括3个数据66B以及1个控制66B：tx_code_0、tx_code_1、tx_code_2以及tx_code_3。将数据66B与控制66B的比特0位与比特1位删除，控制66B把比特6位到比特9位删除掉，在最前面添加4比特1111表示3个数据66B后面跟着1个控制66B，拼成1个256比特数据。然后在最前面添上比特0，得到257B数据，即tx_xcoded。3. When the first three data aredata 66B and the last one iscontrol 66B,bit 0 andbit 1 ofdata 66B andcontrol 66B can be deleted, and control 66B can delete bit 6 to bit 9. Adding 4bits 1111 in front means that 3 data 66Bs are followed by 1control 66B, which is assembled into 1 256-bit data, and then adding abit 0 at the front means that it is 257B with control. For example, as shown in FIG. 7 , three pieces ofdata 66B and one piece ofcontrol 66B are included: tx_code_0, tx_code_1, tx_code_2, and tx_code_3.Delete bit 0 andbit 1 ofdata 66B andcontrol 66B, delete bit 6 to bit 9 ofcontrol 66B, add 4bits 1111 at the front to indicate 3data 66B followed by 1control 66B, spelled 1 256-bit data. Then addbit 0 to the front to get 257B data, namely tx_xcoded.

4、当4个数据都是控制66B时，删除所有的控制66B把比特0位和比特1位，第1个控制66B把比特6位至比特9位删除掉，在最前面添加4比特1112表示4个控制66B，组合为1个256比特数据，然后在最前面添上比特0表示是带控制的257B。例如，如图8所示，包括4个控制66B：tx_code_0、tx_code_1、tx_code_2以及tx_code_3。删除所有的控制66B把比特0位和比特1位，第1个控制66B把比特6位至比特9位删除掉，在最前面添加4比特1112表示4个控制66B，组合为1个256比特数据。然后在最前面添上比特0，得到257B数据，即tx_xcoded。4. When the 4 data are allcontrol 66B, delete all control 66B to removebit 0 andbit 1, and thefirst control 66B deletes bit 6 to bit 9, and add 4bits 1112 at the front to indicate 4control 66B, combined into 1 256-bit data, and then addbit 0 at the front to indicate 257B with control. For example, as shown in FIG. 8, fourcontrols 66B are included: tx_code_0, tx_code_1, tx_code_2, and tx_code_3. Delete all control 66B to removebit 0 andbit 1, thefirst control 66B to delete bit 6 to bit 9, add 4bits 1112 at the front to represent 4control 66B, combined into a 256-bit data . Then addbit 0 to the front to get 257B data, namely tx_xcoded.

在进行66B至257B转码(即步骤4012)后，对得到的257B数据进行扰码(即步骤4013)。扰码通常是对对257B数据进行随机处理，减少连0和连1的出现，从而减少码间干扰和抖动，方便接收端的时钟提取。同时还扩展了基带信号频谱，起到加密的效果。After transcoding from 66B to 257B (ie step 4012), scramble the obtained 257B data (ie step 4013). The scrambling code is usually to randomly process the 257B data to reduce the occurrence of consecutive 0s and consecutive 1s, thereby reducing intersymbol interference and jitter, and facilitating clock extraction at the receiving end. At the same time, the spectrum of the baseband signal is expanded to achieve the effect of encryption.

示例性地，扰码的其中一种实现可以如图9所示。其中，扰码多项式可以是：G(x)＝1+x³⁹+x⁵⁸。通常，扰码是一个循环计算的过程，输入的扰码器的数据是以数据流的形式输入，扰码器输出的扰码后的数据也是以数据流的形式输出。具体地，S0至S57可以理解为串行的同步移位寄存器，持续输入257B数据时，首先与一个数据进行异或运算，该数据为对S38与S57分别输出的数据进行异或运算后的数据，然后输出该与一个数据进行异或运算后的数据，并且输入值S0，通过S0至S57进行移位，并将移位寄存器S38与S57分别输出的值进行异或，并且将异或计算的值继续与输入的数据进行异或计算后输出，并且移位到S0继续进行移位与异或计算。经扰码器输出的数据即以太网接口或FlexE对应的传输数据。Exemplarily, one implementation of the scrambling code may be as shown in FIG. 9 . Wherein, the scrambling code polynomial may be: G(x)=1+x³⁹ +x⁵⁸ . Generally, scrambling is a cyclic calculation process, the data input to the scrambler is input in the form of a data stream, and the scrambled data output by the scrambler is also output in the form of a data stream. Specifically, S0 to S57 can be understood as serial synchronous shift registers. When continuously inputting 257B data, first perform an XOR operation with a data, which is the data after the XOR operation is performed on the data output by S38 and S57 respectively. , and then output the data after XOR operation with one data, and input value S0, shift through S0 to S57, and XOR the values output by shift registers S38 and S57 respectively, and XOR the calculated The value continues to be output after XOR calculation with the input data, and shifted to S0 to continue the shift and XOR calculation. The data output by the scrambler is the transmission data corresponding to the Ethernet interface or FlexE.

可以理解为，首先接收接入PCS子层的任一个以太网业务接口或任一个FlexE接口传输的初始码流数据，确定初始码流数据的处理时隙，根据该处理时隙对该码流数据进行转码，得到转码数据，根据该处理时隙对转码数据进行扰码，以得到以太网接口或与FlexE对应的传输数据，例如，前述的第一传输数据或第二传输数据。因此，可以实现以太网接口与FlexE接口数据的同时获取，可以为每个以太网接口或FlexE接口分配时隙，并在每个时隙处理对应的业务接口的数据，通过时分的方式实现对以太网接口的数据与FlexE接口的数据的处理，节约网络资源。It can be understood that firstly receive the initial code stream data transmitted by any Ethernet service interface or any FlexE interface connected to the PCS sublayer, determine the processing time slot of the initial code stream data, and process the code stream data according to the processing time slot Transcoding is performed to obtain transcoded data, and the transcoded data is scrambled according to the processing time slot to obtain transmission data corresponding to the Ethernet interface or FlexE, for example, the aforementioned first transmission data or second transmission data. Therefore, it is possible to obtain data from Ethernet interfaces and FlexE interfaces at the same time, assign time slots to each Ethernet interface or FlexE interface, and process the data of the corresponding service interface in each time slot. The data of the network interface and the data of the FlexE interface are processed, saving network resources.

然而，FlexO接口传输的数据，已符合后续的进行调度、预处理以及RS-FEC编码等数据需求，因此无需经过转码、扰码等处理，可直接接收FlexO接口传输的数据，后续进行TDM调度、预处理等步骤。即该FlexO接口传输的数据即可作为前述的第一传输数据。通常，FlexO接口传输的是数据流，RS-FEC可以直接对FlexO接口传输的数据流按照257B数据进行处理。因此，在接收到FlexO接口发送的数据后，无需进行处理，即可进行调度与预处理等步骤。However, the data transmitted by the FlexO interface has met the subsequent data requirements for scheduling, preprocessing, and RS-FEC encoding, so it can directly receive the data transmitted by the FlexO interface without transcoding, scrambling, etc., and then perform TDM scheduling , preprocessing and other steps. That is, the data transmitted by the FlexO interface can be used as the aforementioned first transmission data. Usually, the FlexO interface transmits data streams, and the RS-FEC can directly process the data streams transmitted by the FlexO interface as 257B data. Therefore, after receiving the data sent by the FlexO interface, steps such as scheduling and preprocessing can be performed without processing.

此外，PCS子层还可以接收一个或多个Interlaken接口传输的输入数据，其中，可以通过空分的方式实现Interlaken接口传输的输入数据的接口。以其中一个Interlaken接口为例，在接收到任一个Interlaken接口传输的初始码流数据后，首先对接收到的输入数据进行扰码(即步骤4021)，其中，接收到的输入数据为XB长度的数据，X＞＝1，更一步地，扰码的步骤可以与前述步骤4013类似，此处不再赘述。In addition, the PCS sublayer may also receive input data transmitted by one or more Interlaken interfaces, where the interface of the input data transmitted by the Interlaken interfaces may be implemented in a space division manner. Taking one of the Interlaken interfaces as an example, after receiving the initial code stream data transmitted by any Interlaken interface, the received input data is first scrambled (ie step 4021), wherein the received input data is XB length For data, X>=1. Furthermore, the steps of scrambling may be similar to theaforementioned step 4013, and will not be repeated here.

然后对扰码后的XB数据进行XB至YB转码(即步骤4022)。具体可以是在XB前添加n位标识数据，以得到YB数据，n为不小于0的整数。例如，若X＝64，Y＝67，则可以在XB数据前添加3比特的标识数据。例如，可以在64B数据的头部增加001、010、101、110等，其中，001可以标识为数据块，且所有64比特数据位不取反码；010可以标识为控制块，且所有64比特数据位不取反码；101可以标识为数据块，所有64比特数据位取反码；110可以标识为控制块，且所有64比特数据位取反码。Then perform XB to YB transcoding on the scrambled XB data (that is, step 4022). Specifically, n bits of identification data may be added before XB to obtain YB data, where n is an integer not less than 0. For example, if X=64 and Y=67, 3-bit identification data can be added before the XB data. For example, 001, 010, 101, 110, etc. can be added to the head of 64B data, where 001 can be identified as a data block, and all 64-bit data bits are not inverted; 010 can be identified as a control block, and all 64-bit Data bits are not inverted; 101 can be identified as a data block, and all 64-bit data bits are inverted; 110 can be identified as a control block, and all 64-bit data bits are inverted.

在得到YB数据后，继续进行YB至ZB转码(即步骤4023)，以得到Interlaken接口对应的传输数据，即前述图2中的多组传输数据的其中一个。其中，PCS子层可以接入多个Interlaken接口，可以接收多个Interlaken接口传输的输入数据，因此，在对多个输入数据进行处理，得到多个YB数据后，都进行YB至ZB的转码。并且，可以同时处理多个Interlaken接口传输的扰码后的XB数据，在将多个Interlaken接口对应的XB数据转换为YB数据后，后续在进行YB至ZB的转换时，可以为每个YB数据分配时隙，在不同的时隙对每个Interlaken接口对应的YB数据进行处理。因此，在进行YB至ZB转码时，还可以确定每个Interlaken接口对应的时隙，并在对应的时隙对每个YB数据进行处理。具体地，将YB转码为ZB数据的具体过程可以例如，若Y＝67，Z＝130，则可以是将67B数据压缩为65B数据，具体可以是将3位标识数据压缩为1比特的数据。例如，将数据块标识为0，控制块标识为1，得到65B数据。然后将两个65B数据组合起来，即可得到130B数据。该130B数据即可理解为传输数据，例如，前述的第一传输数据或第二传输数据。After obtaining the YB data, continue to transcode from YB to ZB (that is, step 4023 ) to obtain the transmission data corresponding to the Interlaken interface, that is, one of the multiple sets of transmission data in FIG. 2 above. Among them, the PCS sublayer can be connected to multiple Interlaken interfaces, and can receive input data transmitted by multiple Interlaken interfaces. Therefore, after processing multiple input data and obtaining multiple YB data, transcoding from YB to ZB is performed. . In addition, the scrambled XB data transmitted by multiple Interlaken interfaces can be processed at the same time. After converting the XB data corresponding to multiple Interlaken interfaces into YB data, when converting from YB to ZB, each YB data can be Allocate time slots, and process the YB data corresponding to each Interlaken interface in different time slots. Therefore, when transcoding from YB to ZB, the time slot corresponding to each Interlaken interface can also be determined, and each YB data can be processed in the corresponding time slot. Specifically, the specific process of transcoding YB data into ZB data may be, for example, if Y=67, Z=130, then it may be to compress 67B data into 65B data, specifically, it may be to compress 3-bit identification data into 1-bit data . For example, mark the data block as 0 and the control block as 1 to obtain 65B data. Then combine the two 65B data to get 130B data. The 130B data can be understood as transmission data, for example, the aforementioned first transmission data or second transmission data.

需要说明的是，在本申请实施例中，对于每个业务接口的传输数据的获取顺序不作限定，可以是先获取以太网接口对应的传输数据，也可以是先获取FlexO接口对应的传输数据，具体根据实际业务接口的发送对应数据的顺序确定，此处不作限定。It should be noted that, in the embodiment of the present application, the acquisition order of the transmission data of each service interface is not limited, it may be to obtain the transmission data corresponding to the Ethernet interface first, or to obtain the transmission data corresponding to the FlexO interface first, Specifically, it is determined according to the sequence of the corresponding data sent by the actual service interface, which is not limited here.

在得到多组传输数据后，即可进行TDM调度(即步骤403)。为每组传输数据确定对应的传输时隙，并按照每组传输数据对应的传输时隙进行调度处理。After obtaining multiple sets of transmission data, TDM scheduling can be performed (that is, step 403). A corresponding transmission time slot is determined for each group of transmission data, and scheduling processing is performed according to the transmission time slot corresponding to each group of transmission data.

具体地，可以获取多组传输数据，该多组传输数据可以包括步骤4013、步骤4023或直接接收的一个或多个FlexO接口传输的数据等。在获取到该多组传输数据后，可以确定每组传输数据的传输时隙，并根据每组传输数据的传输时隙对获取到的传输数据进行处理。下面以第一传输数据为例进行进一步地说明，第一传输数据为该多组传输数据中的任意一个。Specifically, multiple sets of transmission data may be acquired, and the multiple sets of transmission data may includestep 4013,step 4023 or directly received data transmitted by one or more FlexO interfaces. After the multiple sets of transmission data are acquired, the transmission time slots of each set of transmission data may be determined, and the acquired transmission data may be processed according to the transmission time slots of each set of transmission data. The following takes the first transmission data as an example for further description, where the first transmission data is any one of the multiple sets of transmission data.

其中，可选地，每组传输数据对应的传输时隙可以是预置的，也可以是在获取到传输数据后实时分配的。具体地，若传输时隙为预置的，则在获取该多组传输数据之前，可以为每个接入的业务接口分配与带宽匹配的时隙，并保存在数据库中，在获取到业务接口对应的传输数据后，可以根据该业务接口从数据库中查找该传输数据的传输时隙。若传输时隙为实时分配的，在获取该多组传输数据中的每组传输数据之后，可以根据每组传输数据对应的业务接口的业务类型进行时隙分配，也可以按照每组传输数据的获取顺序进行时隙分配，还可以按照每组传输数据的优先级进行时隙分配等等，为每组传输数据分配的时隙还可以与对应的业务接口的带宽匹配，具体可以根据实际应用场景进行调整。Wherein, optionally, the transmission time slot corresponding to each group of transmission data may be preset, or may be allocated in real time after the transmission data is acquired. Specifically, if the transmission time slot is preset, before obtaining the multiple sets of transmission data, a time slot matching the bandwidth can be allocated for each accessed service interface and stored in the database. After the corresponding data is transmitted, the transmission time slot of the transmitted data can be searched from the database according to the service interface. If the transmission time slots are assigned in real time, after obtaining each group of transmission data in the multiple groups of transmission data, the time slots can be allocated according to the service type of the service interface corresponding to each group of transmission data, or according to the time slot of each group of transmission data The time slots can be allocated according to the priority of each group of transmission data, etc. The time slots allocated for each group of transmission data can also be matched with the bandwidth of the corresponding service interface, which can be determined according to the actual application scenario Make adjustments.

在确定第一传输数据对应的第一传输时隙后，在第一传输时隙对第一传输数据进行预处理(即步骤404)，以得到第一传输数据对应的预处理数据。获取到的多组传输数据中的每组传输数据都可以根据对应的传输时隙进行预处理，以得到每组传输数据对应的预处理数据。After the first transmission time slot corresponding to the first transmission data is determined, preprocessing is performed on the first transmission data in the first transmission time slot (that is, step 404 ), so as to obtain preprocessing data corresponding to the first transmission data. Each of the multiple sets of acquired transmission data may be preprocessed according to a corresponding transmission time slot, so as to obtain preprocessed data corresponding to each set of transmission data.

其中，预处理过程可以包括对第一传输数据进行码块交织分组，得到第一预处理数据。在第一预处理数据中插入对齐标识，得到第二预处理数据。Wherein, the preprocessing process may include performing code block interleaving and grouping on the first transmission data to obtain the first preprocessing data. The alignment identifier is inserted into the first preprocessing data to obtain the second preprocessing data.

具体地，进行码块交织分组，可以将第一传输数据分为多个组。每个组的数据的比特长度为与信道编码器的编码比特长度的整数倍。例如，若信道编码器为RS-FEC编码器，因RS-FEC编码器可以采用基于伽罗华域(Galois Field，GF)的RS编码，每个字符的长度为10比特(bit)。因此，在进行分组时，每组字符都可以为10bit字符的整数倍，以使RS-FEC编码器可以正常编码。例如，若第一传输数据的长度为1000比特，那么，可以将第一传输数据分为n组，n＜＝100，且每组字符的长度为10比特的整数倍。Specifically, performing code block interleaving and grouping may divide the first transmission data into multiple groups. The bit length of the data of each group is an integer multiple of the encoding bit length of the channel encoder. For example, if the channel coder is an RS-FEC coder, since the RS-FEC coder can use Galois Field (Galois Field, GF)-based RS coding, the length of each character is 10 bits (bit). Therefore, when grouping, each group of characters can be an integer multiple of 10bit characters, so that the RS-FEC encoder can encode normally. For example, if the length of the first transmission data is 1000 bits, then the first transmission data can be divided into n groups, n<=100, and the length of each group of characters is an integer multiple of 10 bits.

具体地，进行码块交织分组后，第一预处理数据可以理解为多个数据包。可以在每个数据包中插入与第一业务对应的对齐标识，以便编码器可以对第一预处理数据进行编码。例如，若在每个数据包的起始位添加对齐标识，则编码器在识别到该对齐标识后，即可对对齐标识后的数据进行编码。此外，对齐标识也可以使接收端在接收到该多个数据包编码后的数据后，完成对该多个数据包的对齐，避免数据错位。对齐标识可以是在将传输数据切分后的每个数据包中，预置间隔插入的标识。此外，对齐标识还可以是按照预置方式排列的一段数据、按照数据包的先后顺序排列的序列号等等。Specifically, after code block interleaving and grouping, the first preprocessed data can be understood as multiple data packets. An alignment identifier corresponding to the first service may be inserted into each data packet, so that the encoder can encode the first preprocessed data. For example, if an alignment mark is added to the start bit of each data packet, the encoder can encode the data after the alignment mark after recognizing the alignment mark. In addition, the alignment mark can also enable the receiving end to complete the alignment of the multiple data packets after receiving the encoded data of the multiple data packets, so as to avoid data misalignment. The alignment identifier may be an identifier inserted at a preset interval in each data packet after the transmission data is segmented. In addition, the alignment identifier may also be a piece of data arranged in a preset manner, a sequence number arranged in a sequence of data packets, and the like.

不同的业务接口对应的对齐标识可以相同，也可以不同，具体可以根据实际应用场景调整，此处不作限定。The alignment identifiers corresponding to different service interfaces can be the same or different, and can be adjusted according to actual application scenarios, which is not limited here.

更具体地，对齐标识的插入方式可以参阅标准IEEE802.3中的相关规范。More specifically, the insertion method of the alignment mark may refer to relevant specifications in the standard IEEE802.3.

在进行预处理(即步骤404)，得到第二预处理数据后，可以继续进行编码(即步骤405)，以得到第一码流数据。其中，编码方式可以是RS-FEC编码。After performing preprocessing (ie, step 404) to obtain the second preprocessed data, encoding may continue (ie, step 405) to obtain the first code stream data. Wherein, the encoding manner may be RS-FEC encoding.

其中，具体地，RS-FEC编码的方式可以是，RS-FEC编码器处理k个字符，计算出2t个冗余校验字符，得到的最终字符，字符数为n，n＝k+2t。例如，以常用的RS(544，514)为例，n＝544，k＝514，t＝15。Wherein, specifically, the RS-FEC encoding method may be that the RS-FEC encoder processes k characters, calculates 2t redundant check characters, and obtains a final character whose number of characters is n, where n=k+2t. For example, taking the commonly used RS (544, 514) as an example, n=544, k=514, t=15.

更进一步地，RS-FEC编码的具体过程可以是：Furthermore, the specific process of RS-FEC encoding can be:

消息多项式m(x)除以生成多项式g(x)，获得校验多项式p(x)：Divide the message polynomial m(x) by the generator polynomial g(x) to obtain the check polynomial p(x):

p(x)＝x^n-km(x)mod g(x)。p(x)=x^nk m(x) mod g(x).

生成多项式可以是：

Generator polynomials can be:

消息多项式可以是：m(x)＝m_k-1x^k-1+m_k-2x^k-2+...+m₁x+m₀。The message polynomial may be: m(x)=m_k-1 x^k-1 +m_k-2 x^k-2 +...+m₁ x+m₀ .

可以得到校验多项式可以为：p(x)＝p_2t-1x^2t-1+p_2t-2x^2t-2+...+p₁x+p₀。It can be obtained that the check polynomial can be: p(x)=p_2t-1 x^2t-1 +p_2t-2 x^2t-2 +...+p₁ x+p₀ .

根据上述公式，最终输出的RS-FEC编码多项式可以是：According to the above formula, the final output RS-FEC encoding polynomial can be:

C(x)＝m_n-1^n-1+m_n-2^n-2+...+m_n-kx^n-k-1+p_n-k-1x^n-k-1...+p₀。C(x) = m_n-1^n-1 + m_n-2^n-2 + . . . + m_nk x^nk-1 + p_nk-1 x^{nk-1 .} . . + p₀ .

RS-FEC编码多项式可以理解为消息多项式与校验多项式的组合。其中，该校验多项式用于接收端在获取到数据时，根据数据中携带的数据确定校验多项式，以及预置的生成多项式，来计算数据中携带的消息多项式是否有数据错误，并对错误的数据进行纠错。The RS-FEC encoding polynomial can be understood as a combination of a message polynomial and a check polynomial. Wherein, the check polynomial is used by the receiving end to determine the check polynomial according to the data carried in the data when the receiving end obtains the data, and the preset generator polynomial to calculate whether there is a data error in the message polynomial carried in the data, and correct the error data for error correction.

RS-FEC编码器可以采用不同的n、k取值，获得不同的数据纠错能力，通常，以太网采用的是RS(528，514)和RS(544，514)。The RS-FEC encoder can adopt different values of n and k to obtain different data error correction capabilities. Usually, Ethernet adopts RS(528,514) and RS(544,514).

在进行RS-FEC编码得到第一码流数据后，根据第一码流数据对应的业务接口，对第一码流数据进行一步地分发(即步骤406)。具体地，在进行第一码流数据的分发时，根据第一码流数据对应的业务接口的业务类型的不同，在对应的第一传输时隙，将第一码流数据的虚拟传输通道映射到的物理通道，以通过物理传输通道对第一码流数据进行传输。通常，不同业务类型的业务接口，所对应的传输速率也可能不相同，例如，以太网接口对应的传输速率可以是200GB，FlexE接口对应的传输速率可能是100GB等等。而不同的物理通道的传输速率也可能不相同，因此，根据第一码流数据对应的业务接口的业务类型，确定第一码流数据传输的物理通道，并对第一码流数据进行分发，分发到PMA子层分发至对应的物理通道，并通过PMA子层，发送至接收端。After RS-FEC encoding is performed to obtain the first code stream data, the first code stream data is distributed in one step according to the service interface corresponding to the first code stream data (ie step 406). Specifically, when distributing the first code stream data, according to the service type of the service interface corresponding to the first code stream data, in the corresponding first transmission time slot, the virtual transmission channel of the first code stream data is mapped to the physical channel to transmit the first code stream data through the physical transmission channel. Generally, service interfaces of different service types may have different transmission rates. For example, the transmission rate corresponding to the Ethernet interface may be 200GB, and the transmission rate corresponding to the FlexE interface may be 100GB. The transmission rates of different physical channels may also be different. Therefore, according to the service type of the service interface corresponding to the first code stream data, determine the physical channel for the transmission of the first code stream data, and distribute the first code stream data. Distributed to the PMA sublayer, distributed to the corresponding physical channel, and sent to the receiving end through the PMA sublayer.

在本申请实施例中，PCS子层可以接入多个业务接口，确定每个业务接口传输的数据对应的传输时隙，并在对应的传输时隙对每组传输数据进行处理。因此，RS-FEC编码器可以根据确定的业务接口对应的传输时隙，处理多个相同或不同的业务接口传输的数据，提高RS-FEC编码资源的利用率。并且，每个业务接口之间可以通过时分或空分等方式，实现多个业务接口的接入，并且时隙可以灵活配置，可以灵活接入多种类型的业务接口，在保证接入业务接口的灵活性的同时可以节省网络资源。In the embodiment of the present application, the PCS sublayer can access multiple service interfaces, determine the transmission time slot corresponding to the data transmitted by each service interface, and process each group of transmission data in the corresponding transmission time slot. Therefore, the RS-FEC encoder can process data transmitted by multiple identical or different service interfaces according to the transmission time slot corresponding to the determined service interface, thereby improving the utilization rate of RS-FEC coding resources. Moreover, multiple service interfaces can be accessed through time division or space division between each service interface, and the time slot can be flexibly configured to flexibly access various types of service interfaces. It can save network resources while maintaining flexibility.

前述对本申请实施例提供的数据传输的方法的发送流程进行了具体说明，下面对本申请提供的接收流程进行更具体的说明。The foregoing has specifically described the sending process of the data transmission method provided in the embodiment of the present application, and the receiving process provided in the present application will be described in more detail below.

首先，每组码流数据可能被切分为多个数据包，接收通过PMA子层发送的多个数据包后，可以检索数据包中的对齐标识。在检索到多个数据包中的对齐标识后，将携带对齐标识的数据包锁定(即步骤407)，即重组码流数据前，该数据包无需再进行处理。First, each set of code stream data may be divided into multiple data packets, and after receiving multiple data packets sent through the PMA sublayer, the alignment identifier in the data packet can be retrieved. After the alignment identifiers in the multiple data packets are retrieved, the data packets carrying the alignment identifiers are locked (ie step 407), that is, the data packets do not need to be processed before the code stream data is reassembled.

并在确定码流数据的所有数据包以后，按照不同的业务类型的对齐规则以及传输时隙，根据已经检测到的对齐标识，进行偏斜补偿(即步骤408)。将数据对齐，组合为前述步骤405中进行RS-FEC编码得到的第一码流数据。通过对齐标识消除不同的传输通道间的传输偏差。And after determining all data packets of code stream data, perform skew compensation according to alignment rules and transmission time slots of different types of services, and according to detected alignment marks (ie step 408). The data is aligned and combined into the first code stream data obtained by performing RS-FEC encoding in theaforementioned step 405 . The transmission deviation between different transmission channels is eliminated by aligning the marks.

可选的，在通过对齐标识进行对齐得到第一码流数据后，还可以删除第一码流数据中的对齐标识。当删除对齐标识时，在本申请实施例中，以下步骤中的第一码流数据可以理解为将删除对齐标识后的第一码流数据。Optionally, after the first code stream data is obtained through alignment using the alignment mark, the alignment mark in the first code stream data may also be deleted. When the alignment mark is deleted, in the embodiment of the present application, the first code stream data in the following steps can be understood as the first code stream data after the alignment mark is deleted.

例如，若在每100个字符之间插入对齐标识，那么，在接收到多个数据包后，检测每个数据包中的对齐标识，若其中一个数据包的只有99个字符，那么，可以确认该数据包中有数据错误或数据丢失，此时，可以根据通知PMA重新发送该数据包，或根据预置的规则，恢复该数据错误或数据丢失的字符等。并在码流数据的所有数据包都获取到后，将数据重组为码流数据。For example, if an alignment mark is inserted between every 100 characters, then, after receiving multiple data packets, detect the alignment mark in each data packet, and if one of the data packets has only 99 characters, then it can be confirmed There is a data error or data loss in the data packet. At this time, the data packet can be resent according to the notification PMA, or the character of the data error or data loss can be recovered according to a preset rule. And after all the data packets of the code stream data are obtained, the data is reassembled into the code stream data.

需要说明的是，本申请实施例中具体的对齐标识锁定(即步骤407)与偏斜补偿(即步骤408)可以参阅标准IEEE802.3中的相关规范，此处不再赘述。It should be noted that for the specific alignment mark locking (that is, step 407 ) and skew compensation (that is, step 408 ) in the embodiment of the present application, reference may be made to relevant specifications in the standard IEEE802.3, which will not be repeated here.

可以在获取到多组码流数据后，确定每组码流数据对应的传输时隙，并子在对应的传输时隙对每组码流数据进行解码(即步骤409)。以第一码流数据与第二码流数据为例，在得到第一码流数据后，确定第一码流数据的第一传输时隙，并在第一传输时隙对第一码流数据进行解码。在得到第二码流数据后，确定第二码流数据对应的第二传输时隙，并在第二传输时隙对第二码流数据进行解码。其中，第一码流数据为该多组码流数据中的任意一组码流数据，该第二码流数据为该多组码流数据中除第一码流数据之外的任意一组码流数据。具体的解码步骤为前述步骤405中RS-FEC编码步骤的逆过程。After acquiring multiple sets of code stream data, determine the transmission time slot corresponding to each set of code stream data, and decode each set of code stream data in the corresponding transmission time slot (that is, step 409). Taking the first code stream data and the second code stream data as an example, after the first code stream data is obtained, the first transmission time slot of the first code stream data is determined, and the first code stream data is processed in the first transmission time slot to decode. After obtaining the second code stream data, determine the second transmission time slot corresponding to the second code stream data, and decode the second code stream data in the second transmission time slot. Wherein, the first code stream data is any set of code stream data in the multiple sets of code stream data, and the second code stream data is any set of code stream data in the multiple sets of code stream data except the first code stream data streaming data. The specific decoding step is the reverse process of the RS-FEC encoding step in theaforementioned step 405 .

示例性的，以获取到的多组组码流数据中的任意一组码流数据作为第一码流数据为例，在前述步骤405中，可以理解为，消息多项式除以生成多项式，获得校验多项式，最终输出的RS-FEC编码多项式为消息多项式加上校验多项式。因此，逆过程即为组合得到的编码多项式分为消息多项式与校验多项式。因生成多项式、n与k的值已确定，因此，可以计算出消息多项式与校验多项式，根据校验多项式与生成多项式，即可确定消息多项式中的不正确的比特，以实现对消息多项式的误码纠错，得到第一解码数据。Exemplarily, taking any set of code stream data among the multiple sets of code stream data obtained as the first code stream data as an example, in theaforementioned step 405, it can be understood that the message polynomial is divided by the generator polynomial to obtain the correction The verification polynomial, the final output RS-FEC encoding polynomial is the message polynomial plus the verification polynomial. Therefore, the inverse process is that the combined encoding polynomial is divided into a message polynomial and a check polynomial. Since the values of the generator polynomial, n and k have been determined, the message polynomial and the check polynomial can be calculated, and the incorrect bits in the message polynomial can be determined according to the check polynomial and the generator polynomial, so as to realize the verification of the message polynomial Error correction is performed to obtain the first decoded data.

在对每组码流数据根据对应的传输时隙进行解码后，继续进行重组(即步骤410)，以得到多组传输数据。After decoding each set of code stream data according to the corresponding transmission time slot, continue to recombine (that is, step 410) to obtain multiple sets of transmission data.

具体的重组过程为，针对前述步骤预处理(即步骤404)，因添加了不同业务的对齐标识、进行了码块交织分组等，在获取到每组码流数据后，还需要进行码流数据的重组，包括将码流数据重新组合起来，分为分组之前的字符数，例如，将原10比特的整数倍为一组，分为8比特的整数倍为一组。并且根据不同的业务规则，重组为对应的传输数据。例如，以太网接口、FlexE接口与FlexO接口对应的传输数据长度可以重组为257B，Interlaken接口对应的传输数据的长度可以重组为130B等。The specific reorganization process is, for the preprocessing of the aforementioned steps (that is, step 404), due to the addition of alignment marks of different services, the interleaving and grouping of code blocks, etc., after obtaining each group of code stream data, it is also necessary to perform code stream data The recombination includes recombining the code stream data and dividing them into the number of characters before grouping, for example, dividing the integer multiples of the original 10 bits into a group and dividing them into a group of integer multiples of 8 bits. And according to different business rules, it is reorganized into corresponding transmission data. For example, the transmission data length corresponding to the Ethernet interface, the FlexE interface, and the FlexO interface can be reorganized into 257B, and the transmission data length corresponding to the Interlaken interface can be reorganized into 130B.

在重组得到多组传输数据后，根据每组传输数据对应的传输时隙，对每组传输数据进行分发(即步骤411)。After recombining multiple sets of transmission data, each set of transmission data is distributed according to the transmission time slot corresponding to each set of transmission data (that is, step 411).

以第一传输数据为例，若第一传输数据为以太网接口或FlexE接口对应的传输数据，则将第一传输数据分发至对应的解扰码器，进行解扰码。若第一传输数据为FlexO接口对应的传输数据，则直接将第一传输数据分发至FlexO接口。若第一传输数据为Interlaken接口对应的传输数据，则将第一传输数据分发至转码器进行转码。Taking the first transmission data as an example, if the first transmission data is the transmission data corresponding to the Ethernet interface or the FlexE interface, the first transmission data is distributed to a corresponding descrambler for descrambling. If the first transmission data is transmission data corresponding to the FlexO interface, the first transmission data is directly distributed to the FlexO interface. If the first transmission data is the transmission data corresponding to the Interlaken interface, the first transmission data is distributed to the transcoder for transcoding.

以下以第一传输数据为例，分别针对不同的业务接口进行说明。The following takes the first transmission data as an example to describe different service interfaces respectively.

1、若第一传输数据为Interlaken接口对应的传输数据。1. If the first transmission data is the transmission data corresponding to the Interlaken interface.

首先需要对第一传输数据进行转码(即步骤4121)。第一传输数据的长度为ZB，则可以将ZB转换为YB长度的转码数据。例如，若Z＝130，Y＝67，则可以将130B数据分为两个65B数据，并且将每个65B数据的预置位置的1位数据转换为3位标识数据。例如，将0转换为001、101，将1装换为010、110等，以得到67B数据。其中，001可以标识为数据块，且所有64比特数据位不取反码；010可以标识为控制块，且所有64比特数据位不取反码；101可以标识为数据块，所有64比特数据位取反码；110可以标识为控制块，且所有64比特数据位取反码。Firstly, the first transmission data needs to be transcoded (that is, step 4121). The length of the first transmission data is ZB, then ZB can be converted into transcoded data with a length of YB. For example, if Z=130, Y=67, the 130B data can be divided into two 65B data, and the 1-bit data at the preset position of each 65B data can be converted into 3-bit identification data. For example, convert 0 to 001, 101, and convert 1 to 010, 110, etc. to get 67B data. Among them, 001 can be identified as a data block, and all 64-bit data bits are not inverted; 010 can be identified as a control block, and all 64-bit data bits are not inverted; 101 can be identified as a data block, and all 64-bit data bits Negative code; 110 can be identified as a control block, and all 64 data bits are negated.

然后进行YB至XB转码(即步骤4122)。将YB数据转换为XB数据，具体可以是删除YB数据中的标识数据。例如，若Y＝67，X＝64，且每个YB数据的头部包括3位标识数据，则可以删除头部的3位标识数据，以得到64B数据。Then perform YB to XB transcoding (ie step 4122). Converting the YB data into XB data may specifically delete the identification data in the YB data. For example, if Y=67, X=64, and the header of each YB data includes 3-bit identification data, then the 3-bit identification data in the header can be deleted to obtain 64B data.

然后对XB数据解扰码(即步骤4123)，以得到Interlaken接口对应的业务数据。解扰码的过程为扰码的逆过程，针对前述步骤4021，可以是将XB数据输入到解扰码器中，对输入的数据异或运算，然后进行移位输出。具体地，解扰码的具体过程可以根据扰码多项式进行计算，具体解扰的流程与图9中所示的扰码流程类似，此处不再赘述。Then descramble the XB data (that is, step 4123) to obtain the service data corresponding to the Interlaken interface. The process of descrambling is the reverse process of scrambling. For theaforementioned step 4021, the XB data may be input into the descrambling device, XOR operation is performed on the input data, and then shifted and outputted. Specifically, the specific process of descrambling codes may be calculated according to the scrambling code polynomial, and the specific descrambling process is similar to the scrambling code process shown in FIG. 9 , and will not be repeated here.

在得到Interlaken接口对应的业务数据后，将该业务数据发送至对应的Interlaken接口。After obtaining the service data corresponding to the Interlaken interface, the service data is sent to the corresponding Interlaken interface.

应理解，Interlaken接口的接入数量可以是一个也可以是多个，当有多个Interlaken接口时，进行转码(即步骤4121)得到传输数据后，根据每组传输数据对应的业务接口，分别分发至对应的处理通道进行处理，可以同时对多路数据进行处理，包括转码、解扰码等，并在处理完成得到对应的业务数据后，发送至对应的Interlaken接口。It should be understood that the access quantity of the Interlaken interface can be one or more. When there are multiple Interlaken interfaces, after transcoding (that is, step 4121) to obtain the transmission data, according to the service interface corresponding to each group of transmission data, respectively Distributed to the corresponding processing channel for processing, multiple channels of data can be processed at the same time, including transcoding, descrambling, etc., and after the processing is completed to obtain the corresponding business data, it is sent to the corresponding Interlaken interface.

在本申请实施例中，在进行ZB至YB转码后，可以将YB数据进行进一步地转码、解扰码处理，并且，若有多个YB数据，且对应多个Interlaken接口，则可以同时对每个Interlaken接口对应的YB数据进进行处理，通过空分的方式接入多个Interlaken接口，因此，可以提高处理步骤407至步骤411中所涉及的资源的利用率。In this embodiment of the application, after transcoding from ZB to YB, the YB data can be further transcoded and descrambled, and if there are multiple YB data corresponding to multiple Interlaken interfaces, they can be simultaneously The YB data corresponding to each Interlaken interface is processed, and multiple Interlaken interfaces are connected through space division, so the utilization rate of resources involved in processingsteps 407 to 411 can be improved.

2、若第一传输数据为FlexO接口对应的传输数据。2. If the first transmission data is the transmission data corresponding to the FlexO interface.

若第一传输数据为FlexO接口对应的传输数据，则可以直接将第一传输数据发送至对应的FlexO接口。通常，FlexO接口对应的传输数据的长度为257B，无需进行处理，所以可以直接将FlexO对应的传输数据发送至FlexO接口。接入的FlexO接口可以有一个或者多个，若有多个FlexO接口，则分别将每个FlexO接口的传输数据发送每个FlexO接口。If the first transmission data is transmission data corresponding to the FlexO interface, the first transmission data may be directly sent to the corresponding FlexO interface. Usually, the length of the transmission data corresponding to the FlexO interface is 257B, and no processing is required, so the transmission data corresponding to the FlexO can be directly sent to the FlexO interface. There may be one or more connected FlexO interfaces. If there are multiple FlexO interfaces, the transmission data of each FlexO interface is sent to each FlexO interface.

在本申请实施例中，若第一传输数据对应FlexO接口，则可以直接将第一数据传输至对应的FlexO接口，因此，可以接入一个或多个FlexO接口，提高网络资源的利用率。In the embodiment of the present application, if the first transmission data corresponds to the FlexO interface, the first data can be directly transmitted to the corresponding FlexO interface, therefore, one or more FlexO interfaces can be connected to improve the utilization rate of network resources.

3、若第一传输数据为以太网接口或FlexE接口对应的传输数据。3. If the first transmission data is the transmission data corresponding to the Ethernet interface or the FlexE interface.

若第一传输数据对应的业务接口为以太网接口或FlexE接口，则在进行解扰码(即步骤4131)之前，确定第一传输数据对应的处理时隙。该处理时隙可以是预置的，则在获取到第一传输数据时，可以直接根据第一传输数据对应的业务接口的业务类型，查询该第一传输数据的处理时隙。该处理时隙也可以是在获取到第一传输数据时，为第一传输数据实时分配的。If the service interface corresponding to the first transmission data is an Ethernet interface or a FlexE interface, before descrambling (that is, step 4131 ), the processing time slot corresponding to the first transmission data is determined. The processing time slot may be preset, and when the first transmission data is acquired, the processing time slot of the first transmission data may be queried directly according to the service type of the service interface corresponding to the first transmission data. The processing time slot may also be allocated in real time for the first transmission data when the first transmission data is acquired.

可以将第一传输数据分发至解扰器进行解扰码(即步骤4131)，以得到解扰数据。具体地，解扰码的过程与前述步骤4013中扰码的过程类似。针对前述步骤4013，可以是根据第一传输时隙将第一传输数据输入到解扰码器中，对输入的数据异或运算、移位等输出。The first transmission data may be distributed to a descrambler for descrambling (that is, step 4131), so as to obtain descrambled data. Specifically, the descrambling process is similar to the scrambling process instep 4013 described above. For theaforementioned step 4013, the first transmission data may be input into the descrambler according to the first transmission time slot, and the input data is XORed, shifted and outputted.

具体例如，具体的解扰过程参照前述图9，可以是，若扰码的生成多项式为G(x)＝1+x³⁹+x⁵⁸，首先与一个数据进行异或运算，该数据为对S38与S57分别输出的数据进行异或运算后的数据，然后输出该与一个数据进行异或运算后的数据，并且输入值S0，通过S0至S57进行移位，并将移位寄存器S38与S57分别输出的值进行异或，并且将异或计算的值继续与输入的数据进行异或计算后输出，并且移位到S0继续进行移位与异或计算，以得到解扰数据并输出。For example, referring to the aforementioned Figure 9 for the specific descrambling process, it may be that if the generator polynomial of the scrambling code is G(x)=1+x³⁹ +x⁵⁸ , first perform an XOR operation with a piece of data, which is the pair S38 The data after XOR operation with the data output by S57 respectively, and then output the data after XOR operation with one data, and input value S0, shift through S0 to S57, and shift registers S38 and S57 respectively The output value is XORed, and the value calculated by XOR is continued to be XORed with the input data and then output, and shifted to S0 to continue shifting and XOR calculation to obtain descrambled data and output.

在得到解扰数据后，通常解扰数据的长度为257B，因此，可以根据第一传输数据对应的处理时隙进行257B至66B转码(即步骤4132)。具体地，将257B数据转换为66B数据可以为前述图5至图8中所述的转换过程的逆过程。例如，可以将257数据的比特0位删除，然后剩下的数据平均切分为4个64B数据，然后在每个64B数据头部添加2位标识位，即可得到4个66B数据。其中，该4个66B数据都为数据66B。而当4个66B数据为1个66B数据为控制66B，后面3个数据为数据66B时，则可以将257数据的比特0位至比特4位删除，然后在比特4位之后增加4位控制数据，之后将数据平均切分为4个64B数据，在每个64B数据头部添加2位标识位，即可得到4个66B数据。当前3个数据为数据66B，后1个为控制66B时，将257数据的比特0位至比特4位删除，然后在前述控制数据部分增加4位控制数据，之后将数据平均切分为4个64B数据，在每个64B数据头部添加2位标识位，即可得到4个66B数据。当4个数据都是控制66B时，将257数据的比特0位至比特4位删除，然后在每个控制数据对应的比特位增加对应的控制数据，之后将数据平均切分为4个64B数据，在每个64B数据头部添加2位标识位，即可得到4个66B数据。After obtaining the descrambled data, usually the length of the descrambled data is 257B, therefore, transcoding from 257B to 66B can be performed according to the processing time slot corresponding to the first transmission data (that is, step 4132). Specifically, converting 257B data into 66B data may be an inverse process of the conversion process described above in FIGS. 5 to 8 . For example,bit 0 of 257 data can be deleted, and then the remaining data can be equally divided into four 64B data, and then 2 identification bits can be added to each 64B data header to obtain four 66B data. Wherein, the four pieces of 66B data are alldata 66B. And when the 4 66B data are 1 66B data iscontrol 66B, and the following 3 data aredata 66B, you can deletebit 0 to bit 4 of 257 data, and then add 4 bits of control data after bit 4 , and then divide the data into four 64B data on average, and add 2 identification bits to each 64B data header to obtain four 66B data. When the first three data aredata 66B and the last one iscontrol 66B, deletebit 0 to bit 4 of the 257 data, then add 4-bit control data to the aforementioned control data part, and then divide the data into 4 evenly For 64B data, add 2 identification bits to each 64B data header to get 4 66B data. When the 4 data are allcontrol 66B, deletebit 0 to bit 4 of the 257 data, then add the corresponding control data to the bit corresponding to each control data, and then divide the data into 4 64B data on average , adding 2 identification bits to each 64B data header, you can get 4 66B data.

在进行转码得到66B数据后，根据处理时隙，对66B数据进行分发(即步骤4133)，发送至对应的FlexE接口或以太网接口。其中，若接入有一个或多个FlexE接口，或一个或多个以太网接口，将66B数据分发至对应的FlexE接口或以太网接口。After the 66B data is obtained by transcoding, the 66B data is distributed according to the processing time slot (that is, step 4133), and sent to the corresponding FlexE interface or Ethernet interface. Wherein, if there are one or more FlexE interfaces, or one or more Ethernet interfaces, the 66B data is distributed to the corresponding FlexE interfaces or Ethernet interfaces.

因此，当第一传输数据对应的接口为FlexE接口或以太网接口时，可以根据第一传输数据的处理时隙对第一传输数据进行处理，在处理完成后分发至对应的业务接口。例如，若第一传输数据对应的是FlexE接口，则对第一传输数据根据处理时隙进行解扰码、257B至66B转码后，将66B数据，即第三码流数据分发至该FlexE接口。因此，可以通过时分的方式，对一个或多个FlexE接口，或一个或多个以太网接口对应的传输数据，共用RS-FEC解码资源进行处理，实现多个业务接口的接入，提高网络资源的利用率。Therefore, when the interface corresponding to the first transmission data is a FlexE interface or an Ethernet interface, the first transmission data can be processed according to the processing time slot of the first transmission data, and distributed to the corresponding service interface after the processing is completed. For example, if the first transmission data corresponds to the FlexE interface, then the first transmission data is descrambled and transcoded from 257B to 66B according to the processing time slot, and then the 66B data, that is, the third code stream data, is distributed to the FlexE interface . Therefore, the transmission data corresponding to one or more FlexE interfaces or one or more Ethernet interfaces can be processed in a time-division manner by sharing RS-FEC decoding resources to realize the access of multiple service interfaces and improve network resources. utilization rate.

在本申请实施例中，在接收到PMA子层发送过来的码流数据后，对该码流数据进行处理，包括AM锁定、偏斜补偿、解码、重组、分发等步骤，业务接口对应的数据分配对应的传输时隙，实现对多个业务接口对应的数据的处理。因此，可以接入一个或多个相同或不同的业务接口，实现对一个或多个相同或不同的业务接口的数据的处理，节约网络资源，相对于一个业务接口对应一个RS-FEC编码器，本申请实施例提供的数据传输方法可以结合时分与空分的方式，实现多个相同或不同的业务接口共用RS-FEC资源，提高RS-FEC资源的利用率。并且，可以灵活地接入多种类型的业务接口，提高对多种类型的业务接口对应的数据的处理效率。In the embodiment of this application, after receiving the code stream data sent by the PMA sublayer, the code stream data is processed, including steps such as AM locking, skew compensation, decoding, reorganization, and distribution, and the data corresponding to the service interface The corresponding transmission time slots are allocated to realize the processing of data corresponding to multiple service interfaces. Therefore, one or more same or different service interfaces can be connected to realize data processing of one or more same or different service interfaces, saving network resources. Compared with one service interface corresponding to one RS-FEC encoder, The data transmission method provided by the embodiment of the present application can combine time division and space division to realize the sharing of RS-FEC resources by multiple identical or different service interfaces and improve the utilization rate of RS-FEC resources. Moreover, various types of service interfaces can be flexibly connected, and the efficiency of processing data corresponding to various types of service interfaces can be improved.
