Wherein, the
在一个实施例中，如图2所示，提供了一种数据冗余保护方法，以该方法应用于图1中的终端为例进行说明，包括以下步骤：In one embodiment, as shown in FIG. 2 , a data redundancy protection method is provided. The method is applied to the terminal in FIG. 1 as an example for illustration, including the following steps:
步骤201，获取各个编程接口对应的网际协议地址和端口信息，其中，各个编程接口对应的网际协议地址处于相应的各个网段，端口信息相同；Step 201, obtaining the IP address and port information corresponding to each programming interface, wherein the IP address corresponding to each programming interface is in each corresponding network segment, and the port information is the same;
步骤202，根据网际协议地址和端口信息，获得各个编程接口对应的数据和数据的接收时间，其中，数据包括时间标识；
步骤203，根据时间标识和接收时间，对各个编程接口对应的数据进行传输。
上述数据冗余保护方法中，通过获取同一网络节点的各个编程接口对应的网际协议地址和端口信息进行数据冗余保护，其中，各个编程接口对应的网际协议地址处于相应的各个网段，各个网段均不同，根据网际协议地址和端口信息，获得各个编程接口对应的数据和数据的接收时间，其中，数据包括时间标识，根据时间标识和接收时间，对各个编程接口对应的数据进行传输，从而提高了数据传输的可靠性。In the above data redundancy protection method, data redundancy protection is performed by obtaining the IP address and port information corresponding to each programming interface of the same network node, wherein, the IP address corresponding to each programming interface is in each corresponding network segment, and each network The segments are all different, and according to the Internet protocol address and port information, the data corresponding to each programming interface and the receiving time of the data are obtained, wherein the data includes a time stamp, and the data corresponding to each programming interface is transmitted according to the time stamp and receiving time, so that The reliability of data transmission is improved.
目前车载通信的主要方式为以太网通信，而套接字(socket)是在通信中的网络应用层和传输层之间的一个抽象层，它将网络通信中的复杂操作抽象为简单的接口供网络应用层调用已实现网络进程的通信，而中央网关和区域网关作为车载通信中数据传输的重要节点，当其中的物理链接断开时，易造成中央网关和区域网关间的数据丢失，从而限制目前车载通信技术的发展，因此对中央网关和区域网关的数据保护尤为重要，在步骤201中，示例性地说明，获取各个编程接口对应的网际协议地址和端口信息，其中，各个编程接口对应的网际协议地址处于相应的各个网段，端口信息相同，例如，为了对车载通信中的数据进行保护，可以提供一种数据冗余的保护方法，该方法将编程接口设置在socket层，即在需要数据冗余保护的每个网络节点设置多个物理链路，对其中每个物理链路分别绑定一个网际协议(Internet Protocol，IP)地址和端口信息，同时，为了降低当物理链路断开时，数据传输延时的干扰，需要减少切换传输路径带来的延时可能性，因此，可以将各个I P地址设置在相应的各个网段，各个网段均不相同，进一步，为了达到数据冗余的效果，可以将端口信息均设置为相同，此处以设置两个物理链路为例，如图3所示，例如，可以在中央网关和区域网关分别设置两个网口并进行连接，即网口1和网口2，同时，中央网关和区域网关的网口通过网线或者线束进行物理链接，网口1对应一个socket,即socket1_sever，网口2对应一个socket,即socket2_sever，在中央网关的网口1配置静态IP地址为192.168.100.1，网口2配置静态IP地址为10.10.2.1，在区域网关的网口1的IP地址192.168.100.2，网口2配置静态IP地址为10.10.2.2，端口信息均为10000，在中央网关创建socket的服务(sever)端，对端口10000进行监听，等待区域网关进行连接。At present, the main way of vehicle communication is Ethernet communication, and socket (socket) is an abstraction layer between the network application layer and the transport layer in communication, which abstracts the complex operations in network communication into simple interfaces for The network application layer call has realized the communication of the network process, and the central gateway and the regional gateway are important nodes for data transmission in the vehicle communication. When the physical link is disconnected, the data between the central gateway and the regional gateway is easily lost, thus limiting With the current development of in-vehicle communication technology, it is particularly important to protect the data of the central gateway and the regional gateway. In step 201, it is exemplarily explained that the Internet Protocol address and port information corresponding to each programming interface is obtained, wherein the corresponding to each programming interface The Internet protocol address is in each corresponding network segment, and the port information is the same. For example, in order to protect the data in the vehicle communication, a data redundancy protection method can be provided. This method sets the programming interface at the socket layer, that is, when needed Each network node for data redundancy protection is provided with multiple physical links, and each physical link is bound with an Internet Protocol (Internet Protocol, IP) address and port information. At the same time, in order to reduce the When the data transmission delay interferes, it is necessary to reduce the possibility of delay caused by switching the transmission path. Therefore, each IP address can be set in each corresponding network segment, and each network segment is different. Further, in order to achieve data redundancy To achieve the desired effect, the port information can be set to be the same. Here, two physical links are set as an example, as shown in Figure 3. For example, two network ports can be set and connected on the central gateway and the regional gateway respectively, that is,
在步骤202中，示例性地说明，根据网际协议地址和端口信息，获得各个编程接口对应的数据和数据的接收时间，其中，数据包括时间标识，例如，在获取了IP地址和端口信息之后，网络节点之间就可以通过socket进行通信，从而获得相应的数据，而由于存在多个物理链路对数据进行传输，则在接收数据时就会接收到重复的数据，为了避免接收多个重复数据，在接收时可以对接收的重复数据进行处理，在一些实施过程中，可以在发送数据前对数据打上时间标识，重复的数据具有相同的时间标识，因此可以根据时间标识初步判定数据是否重复，从而对重复数据进行进一步处理。In
在步骤203中，示例性地说明，根据时间标识和接收时间，对各个编程接口对应的数据进行传输，例如，为了避免接收多个重复数据，在接收时可以对接收的重复数据进行处理，在一些实施过程中，可以在发送数据前对数据打上时间标识，重复的数据具有相同的时间标识，因此可以根据时间标识初步判定数据是否重复，从而对重复数据进行进一步处理，进一步地，可以依据接收时间对重复数据进行进一步进行处理，如可以按照先到先处理，后到则丢弃的原则，对于先到达的数据进行接收，后到达的数据则进行丢弃，以图3为例，当中央网关与区域网关连接成功后，中央网关通过面向服务的可伸缩的协议(Scalableservice-Oriented MiddlewarE over IP，SOME/IP)将数据发送到适配(Adapter)层时将数据打上时间标识，然后将打上时间标识的两帧完全一样的数据同时发送至socket1_sever和socket2_sever，区域网关的Adapter层收到两个同样时间标识的数据时，按照接收时间，对两个同样时间标识的数据进行选收并上报给区域网关的SOME/IP协议栈进行处理，在一些实施过程中，为了进一步确保重复数据处理的准确性，除了判定时间标识时是否相同以外，还可以判断数据报文是否相同，若时间标识和数据报文均相同，则为重复数据，当区域网关向中央网关发送数据时，也可参照上述步骤进行处理，在此不再赘述。In
作为步骤203的一种具体实现方式，根据时间标识和接收时间，对各个编程接口对应的数据进行传输，包括；判断各个编程接口对应的数据的时间标识是否相同；若是，则根据接收时间，对各个编程接口对应的数据进行选收处理，获得选收处理后的数据；对选收处理后的数据进行传输。As a specific implementation of
需要说明的是，为了对数据进行冗余保护，可以在发送数据之前，将数据打上时间标识，时间标识可以根据发送时间确定，然后根据设置的物理链路的数量，对已经打上时间标识的数据进行复制，并通过各个socket将数据进行同步发送，在其他接收数据的网络节点获取数据以及对应的接收时间，判断获取的各个数据的时间标识是否相同，若相同，则说明获取的数据为重复数据，将这些重复数据对应的接收时间进行对比，从中确定一个接收时间所对应的数据，作为选收后需要上报的数据，而其他重复数据则进行丢弃处理。It should be noted that, in order to protect the redundancy of the data, the data can be stamped with a time stamp before sending the data. The time stamp can be determined according to the sending time, and then according to the number of physical links set, the time stamped data can be Make a copy, and send the data synchronously through each socket, obtain the data and the corresponding receiving time at other network nodes that receive the data, and judge whether the time stamps of the obtained data are the same, if they are the same, it means that the obtained data is duplicate data , compare the receiving time corresponding to these duplicate data, and determine the data corresponding to a receiving time as the data that needs to be reported after selection, while other duplicate data are discarded.
作为上述实施例的一种实现方式，若是，则根据接收时间，对各个编程接口对应的数据进行选收处理，获得选收处理后的数据，包括：对比各个编程接口对应的数据的接收时间，获得对比结果；根据对比结果，对各个编程接口对应的数据进行选收处理，获得选收处理后的数据。As an implementation of the above embodiment, if yes, according to the receiving time, the data corresponding to each programming interface is selected and processed, and the data after the selective receiving processing is obtained, including: comparing the receiving time of the data corresponding to each programming interface, The comparison result is obtained; according to the comparison result, the data corresponding to each programming interface is selected and processed, and the selected and processed data is obtained.
需要说明的是，优选地，可以按照先到先处理，后到则丢弃的原则，将接收时间进行对比，即先到的数据作为需要上报传输的数据，而后到的数据则进行丢弃，以确保数据的时效性，相反，如果按照后到先处理的原则，则需要对数据进行存储等待，直到所有重复数据均接收才能进行传输，这就易导致数据的传输存在延时，降低数据传输的可靠性。It should be noted that, preferably, the receiving time can be compared according to the principle of first-come-first-handed, and later-arriving, that is, the first-arriving data is regarded as the data that needs to be reported for transmission, while the later-arriving data is discarded, so as to ensure The timeliness of data, on the contrary, if the principle of last come first processing is followed, the data needs to be stored and waited until all duplicate data are received before transmission, which will easily lead to delays in data transmission and reduce the reliability of data transmission sex.
作为步骤202的一种具体实现方式，根据网际协议地址和端口信息，获得各个编程接口对应的数据和数据的接收时间，其中，数据包括时间标识，包括：根据网际协议地址和端口信息，获得待发送的数据，其中，数据包括时间标识；根据各个编程接口，对待发送的数据进行复制，获得各个编程接口对应的数据；将各个编程接口对应的数据进行发送，获得各个数据对应的接收时间。As a specific implementation of
需要说明的是，可以根据网络节点中的编程接口，即socket的数量，进行同等数量的复制，然后将数据进行同步发送至两个编程接口，以图3所示为例，中央网关和/或区域网关的Adapter层对数据进行复制后分别同步发送至对应的socket。It should be noted that the same amount of replication can be performed according to the programming interface in the network node, that is, the number of sockets, and then the data is sent to the two programming interfaces synchronously. Taking Figure 3 as an example, the central gateway and/or The Adapter layer of the regional gateway copies the data and sends them to the corresponding sockets synchronously.
作为上述实施例的一种实现方式，根据对比结果，对各个编程接口对应的数据进行选收处理，获得选收处理后的数据，包括：根据对比结果，确定最小的接收时间对应的数据，获得选收处理后的数据。As an implementation of the above embodiment, according to the comparison result, the data corresponding to each programming interface is selected and processed, and the data after the selection processing is obtained, including: according to the comparison result, the data corresponding to the minimum receiving time is determined to obtain Collect the processed data.
作为上述实施例的一种实现方式，判断各个编程接口对应的数据的时间标识是否相同之前，包括：判断各个编程接口对应的物理链路的连接状态；若连接状态为连接的物理链路的数量大于或等于物理链路阈值，则判断各个编程接口对应的数据的时间标识是否相同。As an implementation of the above-mentioned embodiment, before judging whether the time stamps of the data corresponding to each programming interface are the same, it includes: judging the connection status of the physical link corresponding to each programming interface; if the connection status is the number of connected physical links is greater than or equal to the physical link threshold, then it is judged whether the time stamps of the data corresponding to each programming interface are the same.
需要说明的是，数据冗余保护的前提是存在多个物理链路进行连接，即存在多个物理链路进行连接时，才会有多个重复数据需要在接收时进行选收处理，否则会导致接收到多个重复数据的情况发生，但当不需要对重复数据进行处理或者不存在重复数据处理的情况下，为了进一步提高数据传输的效率，则可以不对重复数据进行处理，在一些实施过程中，可以根据需要，通过连接的物理链路的数量设置物理链路阈值进行数据处理的判定，当连接状态为连接的物理链路的数量大于或等于物理链路阈值时，则重复数据较多，需要对重复数据进行处理，当连接状态为连接的物理链路的数量小于物理链路阈值时，则不用对重复数据进行处理。It should be noted that the premise of data redundancy protection is that there are multiple physical links for connection, that is, when there are multiple physical links for connection, there will be multiple duplicate data that need to be selectively received when receiving, otherwise it will be The situation of receiving multiple duplicate data occurs, but when the duplicate data does not need to be processed or there is no duplicate data processing, in order to further improve the efficiency of data transmission, the duplicate data may not be processed. In some implementation processes In , you can set the physical link threshold based on the number of connected physical links to determine data processing. When the connection status is that the number of connected physical links is greater than or equal to the physical link threshold, there will be more duplicate data. , the repeated data needs to be processed, and when the number of connected physical links in the connection state is less than the physical link threshold, the repeated data does not need to be processed.
作为上述实施例的一种实现方式，判断各个编程接口对应的物理链路的连接状态，还包括：若连接状态为断开的物理链路的数量小于物理链路阈值，则对数据进行传输。As an implementation of the above embodiment, judging the connection status of the physical links corresponding to each programming interface further includes: if the number of disconnected physical links is less than the physical link threshold, transmitting data.
在一些实施过程中，可以将物理链路阈值设置为2，因为当连接状态为连接的物理链路的数量小于2时，说明此刻只有一个物理链路可以进行数据传输，则不存在重复数据，因此不需要进行选收处理，从而提高了数据传输的效率。In some implementation processes, the physical link threshold can be set to 2, because when the number of connected physical links in the connection state is less than 2, it means that only one physical link can perform data transmission at this moment, and there is no duplicate data. Therefore, selective receiving processing is not required, thereby improving the efficiency of data transmission.

Unless otherwise specified herein, there is no strict order restriction on the execution of these steps, and these steps can be executed in other orders.
