2. Video networking packet definition

2.1 Access network packet definition

The data packet of the access network mainly comprises the following parts: destination Address (DA), Source Address (SA), reserved bytes, payload (pdu), CRC.

As shown in the following table, the data packet of the access network mainly includes the following parts:

the Destination Address (DA) is composed of 8 bytes (byte), the first byte represents the type of the data packet (such as various protocol packets, multicast data packets, unicast data packets, etc.), there are 256 possibilities at most, the second byte to the sixth byte are metropolitan area network addresses, and the seventh byte and the eighth byte are access network addresses;

the Source Address (SA) is also composed of 8 bytes (byte), defined as the same as the Destination Address (DA);

the reserved byte consists of 2 bytes;

the payload part has different lengths according to different types of data packets, and is 64 bytes if various protocol packets are used, or 32+1024 or 1056 bytes if a unicast data packet is used, although not limited to the above 2 types;

the CRC consists of 4 bytes and is calculated in accordance with the standard ethernet CRC algorithm.

2.2 metropolitan area network packet definition

The topology of a metropolitan area network is a graph and there may be 2, or even more than 2, connections between two devices, i.e., there may be more than 2 connections between a node switch and a node server, a node switch and a node switch, and a node switch and a node server. However, the metro network address of the metro network device is unique, and in order to accurately describe the connection relationship between the metro network devices, parameters are introduced in the embodiment of the present invention: a label to uniquely describe a metropolitan area network device.

In this specification, the definition of the Label is similar to that of the Label of MPLS (Multi-Protocol Label Switch), and assuming that there are two connections between the device a and the device B, there are 2 labels for the packet from the device a to the device B, and 2 labels for the packet from the device B to the device a. The label is classified into an incoming label and an outgoing label, and assuming that the label (incoming label) of the packet entering the device a is 0x0000, the label (outgoing label) of the packet leaving the device a may become 0x 0001. The network access process of the metro network is a network access process under centralized control, that is, address allocation and label allocation of the metro network are both dominated by the metro server, and the node switch and the node server are both passively executed, which is different from label allocation of MPLS, and label allocation of MPLS is a result of mutual negotiation between the switch and the server.

As shown in the following table, the data packet of the metro network mainly includes the following parts:

Namely Destination Address (DA), Source Address (SA), Reserved byte (Reserved), tag, payload (pdu), CRC. The format of the tag may be defined by reference to the following: the tag is 32 bits with the upper 16 bits reserved and only the lower 16 bits used, and its position is between the reserved bytes and payload of the packet.

Based on the characteristics of the video networking, the data processing scheme of the individual device provided by the embodiment of the invention follows the protocol of the video networking, adopts a more flexible mode to access the individual device to the WIFI network, and realizes communication between the non-video-networking device, namely the individual device, and the video-networking device.

Example one

In the embodiment of the invention, the internet can comprise a 4G router, an LTE gateway, individual equipment and a streaming media server, and the video network can comprise a video network server and a video network terminal. The streaming media server and the video network server can communicate with each other, so that the internet equipment and the video network equipment can communicate with each other.

Referring to fig. 5, a flowchart illustrating steps of a data processing method for individual soldier equipment according to a first embodiment of the present invention is shown.

The data processing method of the individual soldier equipment in the embodiment of the invention can comprise the following steps:

step 501, the LTE gateway receives the 4G signal output by the 4G router, and converts the 4G signal into a first WIFI signal.

The 4G router is a router which is connected to the internet based on a 4G telephone card and can share a WIFI (WIreless-FIdelity) signal and a mobile network bandwidth. The 4G router is an industrial Internet of things high-speed router, is compatible with a 4G/3.5G/3G/2.5G network in a whole line, can easily establish a high-speed and stable wireless transmission network, and provides a wireless Long-distance data transmission function for users by utilizing a public LTE (Long Term Evolution) network.

The LTE gateway is an integrated intelligent gateway integrating functions of a voice gateway, a wireless router, and the like, and can convert different network signals. The LTE gateway can be connected with the 4G router, and the 4G router exports the 4G signal to the LTE gateway, and after the LTE gateway received the 4G signal of 4G router output, can convert this 4G signal into first WIFI signal.

Step 502, the individual device receives a first WIFI signal output by the LTE gateway and accesses a WIFI network.

The real-time audio and video information of the scene is instantly transmitted back to a background monitoring center through network signals when the real-time audio and video information is carried by related personnel or a handheld device goes to the scene during daily work or handling emergencies, and the real-time audio and video information is similar to a tool which is necessary for an individual soldier, so the real-time audio and video information transmission terminal is also called an individual soldier drawing transmission terminal (namely individual soldier equipment) and is widely applied to the instant wireless image transmission of various uncertain places such as public inspection, customs, fire control, traffic, electric power, oil fields, mines, emergency commands, waterpower, buildings and the like.

In the embodiment of the invention, the individual device can receive the first WIFI signal output by the LTE gateway, access the WIFI network through the first WIFI signal, and perform network communication, such as video data transmission, audio data transmission and the like, by using the WIFI network after the access.

Step 503, if the streaming media server receives first data sent by the individual soldier device through the WIFI network and determines that the first data is to be sent to the video networking terminal, the streaming media server performs conversion processing on the first data to obtain second data, and sends the second data to the video networking terminal through the video networking server.

The streaming media server is called streaming media for short, and mainly has the functions of collecting, caching, scheduling, transmitting and playing media contents of audio, video and multimedia files transmitted in a network.

The individual soldier equipment can collect external data. External speech can be collected by a microphone and encoded into audio data; or the external video pictures can be collected by the camera and coded into video data, and the like.

The individual soldier equipment can communicate with the streaming media server through the WIFI network. For example, the individual device sends the first data (such as audio data or video data encoded by the individual device) to the streaming media server through the WIFI network. If the streaming media server determines that the first data are to be sent to the terminal of the video network, the streaming media server converts the first data to obtain second data in order to enable the first data to be smoothly transmitted in the video network, and sends the second data to the terminal of the video network through the video network via the server of the video network.

Step 504, if the streaming media server receives third data sent by the video networking terminal through the video networking via the video networking server and determines that the third data is to be sent to the individual soldier equipment, the streaming media server converts the third data to obtain fourth data, and sends the fourth data to the individual soldier equipment through the WIFI network.

The video network terminal can collect external data. External speech can be collected by a microphone and encoded into audio data; or the external video pictures can be collected by the camera and coded into video data, and the like.

The video network terminal can communicate with the video network server through the video network, and the video network server can communicate with the streaming media server through the video network, so that the video network terminal can communicate with the streaming media server through the video network via the video network server. For example, the terminal of the video network sends the third data (audio data or video data coded by the terminal of the video network) to the streaming media server through the video network via the video network server. And if the streaming media server determines that the third data are to be sent to the individual soldier equipment, the streaming media server converts the third data to obtain fourth data in order to enable the third data to be transmitted in the internet smoothly, and sends the fourth data to the individual soldier equipment through the WIFI network.

It should be noted that the conversion process may be executed in the streaming media server, or may be executed in another device independent from the streaming media server, and the embodiment of the present invention is not limited to this.

In the embodiment of the invention, the mode of accessing the individual soldier equipment into the network is more flexible, and the problems of complex wired access mode and large limitation are avoided; and can realize that the data transmission of individual soldier's equipment reaches the video networking terminal to and transmit the data transmission of video networking terminal to individual soldier's equipment, thereby realize that this kind of non-video networking's of individual soldier's equipment also can communicate with the equipment of video networking.

Example two

Referring to fig. 6, a flowchart of steps of a data processing method for individual equipment according to a second embodiment of the present invention is shown.

step 601, the LTE gateway receives the 4G signal output by the 4G router and converts the 4G signal into a first WIFI signal.

In the embodiment of the invention, a 4G router, an LTE gateway, CPE and individual equipment are deployed in the Internet. The individual device can access the WIFI network through all devices or part of devices in the 4G router, the LTE gateway and the CPE.

The 4G router can provide an RS232 (or RS485/RS422) interface, a LAN interface, a WAN interface and a WIFI interface, can be connected with serial port equipment, Ethernet equipment and WIFI equipment at the same time, and achieves transparent data transmission and routing functions.

The LTE gateway may provide a WAN interface. The LTE gateway can be in wired connection with the WAN interface of the 4G router through the WAN interface of the LTE gateway. Therefore, the 4G router can output the 4G signal through its WAN interface and input it into the LTE gateway through the WAN interface of the LTE gateway.

The LTE gateway may also provide a WIFI interface. The LTE gateway receives the 4G signal output by the 4G router, can convert the 4G signal into a first WIFI signal, and outputs the first WIFI signal through a WIFI interface of the LTE gateway. For a specific process of converting the 4G signal into the first WIFI signal by the LTE gateway, a person skilled in the art may perform related processing according to actual experience, and this is not discussed in detail in the embodiment of the present invention.

Step 602, the CPE receives the 4G signal output by the LTE gateway, and converts the 4G signal into a second WIFI signal.

The CPE refers to LTE data terminal equipment for converting high-speed 4G signals into WIFI signals. The CPE can undertake the task of converting LTE gateway wireless data and Ethernet wired data, has a return function, can be independently used and is used for outdoor deployment.

The LTE gateway may also provide a data network interface, as may the CPE. The LTE gateway may be connected to the data network interface of the CPE through its own data network interface. Therefore, the LTE gateway can output the 4G signal through its own data network interface and input it into the CPE through its data network interface.

The CPE may also provide a WIFI interface. The CPE receives the 4G signal output by the LTE gateway, converts the 4G signal into a second WIFI signal and outputs the second WIFI signal through a WIFI interface of the CPE. For a specific process of converting the 4G signal into the second WIFI signal by the CPE, a person skilled in the art may perform related processing according to actual experience, and this is not discussed in detail in the embodiment of the present invention.

And step 603, accessing the individual equipment to the WIFI network.

In the embodiment of the invention, the individual soldier equipment can access the WIFI network through the LTE gateway and also can access the WIFI network through the CPE.

In one embodiment, an individual device may provide a WIFI interface. The LTE gateway can be connected with a WIFI interface of the individual soldier equipment through the WIFI interface of the LTE gateway. Therefore, the LTE gateway can output the first WIFI signal through the WIFI interface of the LTE gateway and input the first WIFI signal into the individual soldier equipment through the WIFI interface of the individual soldier equipment. Under the condition, the individual soldier equipment receives a first WIFI signal output by the LTE gateway and accesses the WIFI network through the first WIFI signal.

In another embodiment, an individual device may provide a WIFI interface. The CPE can be connected with a WIFI interface of the individual soldier equipment through the WIFI interface of the CPE. Therefore, the CPE can output the second WIFI signal through its own WIFI interface and input it into the individual soldier device through its WIFI interface. Under the condition, the individual soldier equipment receives a second WIFI signal output by the CPE and accesses the WIFI network through the second WIFI signal.

Referring to fig. 7, a schematic diagram of an individual device accessing a WIFI network according to a second embodiment of the present invention is shown. As can be seen from fig. 7, the devices involved therein include a 4G router, an LTE gateway, a CPE, and a plurality of individual devices. The LTE gateway is in wired access to the 4G router and receives a 4G signal sent by the 4G router; the LTE gateway can convert the 4G signal into a WIFI signal; the LTE gateway may also output the 4G signal to the CPE; the CPE can convert the 4G signals into WIFI signals; each individual soldier device can be accessed to the WIFI network through the WIFI signal output by the LTE gateway, and can also be accessed to the WIFI network through the WIFI signal output by the CPE.

Step 604, if the streaming media server receives first data sent by the individual soldier equipment through the WIFI network and determines that the first data is to be sent to the video networking terminal, the streaming media server converts the first data to obtain second data, and the second data is sent to the video networking terminal through the video networking server.

The streaming media server is deployed in the Internet, and the video network server and the video network terminal are deployed in the video network. Two network cards can be provided on the streaming media server, one network card is connected with the internet, and for example, the network card interacts with individual soldier equipment through the internet (such as a WIFI network); and the other network card is connected with the video network, such as interacting with a video network server through the video network.

If the streaming media server receives first data sent by the individual soldier equipment through the WIFI network, whether the first data are sent to the video networking terminal or not can be determined. For example, the first data may include an identification of the target device to be transmitted to, and the streaming server may determine whether the first data is to be transmitted to the video network terminal based on the identification. If the identification of the target device comprises an identification of the video network terminal (such as a user number of the video network terminal), determining that the first data is to be sent to the video network terminal; if the identification of the target device includes the identification of the other individual device, it may be determined that the first data is to be sent to the other individual device.

If the streaming media server determines that the first data is to be sent to the video network terminal, the video network terminal cannot directly process the first data because the first data is coded by the individual device and is based on an internet protocol and coded in a format supported by the individual device.

Therefore, the streaming media server can convert the first data into the second data. The specific conversion process may include:

a1, the streaming media server sends the first data to the transcoding server;

since the encoding and decoding consume resources such as memory and a Central Processing Unit (CPU), the streaming server may send the first data to a separate transcoding server for conversion. Therefore, a transcoding server can be deployed in the internet, and the streaming media server can communicate with the transcoding server through the internet.

a2, the streaming media server acquires data which is returned by the transcoding server and is suitable for the processing format of the video networking terminal and is obtained based on the transcoding of the first data;

in a specific implementation, a transcoding process may be established inside the streaming media server, and if the first data is to be sent to the video networking terminal, the streaming media server enters the transcoding process and sends the first data to the transcoding server. And the transcoding server receives the first data, and transcodes the first data into data in a format suitable for being processed by the video networking terminal when detecting that the coding format of the first data is the format supported by the individual soldier equipment, namely, the first data is transcoded into data in a format supported by the video networking terminal. Optionally, the transcoding server decodes the first data with the encoding format supported by the individual device into corresponding PCM (Pulse Code Modulation) data, processes the PCM data, and encodes the PCM data into data with the encoding format supported by the video networking terminal.

And a transcoding receiving thread can be established in the streaming media server, and data which is returned by the transcoding server and is transcoded based on the first data and is in a format suitable for processing by the video network terminal can be acquired through the thread. Therefore, the data in the format suitable for the video network terminal to process is data based on the Internet protocol and in the format supported by the video network terminal in an encoding format.

a3, the stream media server converts the data in the format suitable for the terminal of the video network into the data based on the video network protocol as the second data.

The streaming media server can also convert the data in the format suitable for the video network terminal to be processed into data based on the video network protocol as second data, because the data in the format suitable for the video network terminal to be processed is subsequently transmitted to the video network terminal. Thus, the second data is data based on the video networking protocol and encoded in a format supported by the video networking terminal.

And after the streaming media server obtains the second data, the second data is sent to the video network terminal through the video network via the video network server. Specifically, the streaming media server sends the second data to the video network server through the video network, and the video network server sends the second data to the video network terminal through the video network.

In a preferred embodiment, the streaming media server sends the second data to the video network server through the video network, and sends the second data to the video network terminal through the video network server according to a downlink communication link configured for the video network terminal.

In a specific implementation, the video network terminal may be a Set Top Box (STB), commonly referred to as a Set Top Box or Set Top Box, which is a device for connecting a tv Set and an external signal source, and may convert a compressed digital signal into tv content and display the tv content on the tv Set.

In practical applications, the video network is a network with a centralized control function, and includes a main control server and a lower level network device, where the lower level network device includes a terminal, and one of the core concepts of the video network is that a table is configured by notifying a switching device of a downlink communication link for a current service by the main control server, and then a data packet is transmitted based on the configured table.

Namely, the communication method in the video network includes:

and the main control server configures the downlink communication link of the current service.

And transmitting the data packet of the current service sent by the source terminal to a target terminal (such as a video network terminal) according to the downlink communication link.

In the embodiment of the present invention, configuring the downlink communication link of the current service includes: and informing the switching equipment related to the downlink communication link of the current service to allocate the table.

Further, transmitting according to the downlink communication link includes: the configured table is consulted, and the switching equipment transmits the received data packet through the corresponding port.

In particular implementations, the services include unicast communication services and multicast communication services. Namely, whether multicast communication or unicast communication, the core concept of the table matching-table can be adopted to realize communication in the video network.

As mentioned above, the video network includes an access network portion, in which the master server is a node server and the lower-level network devices include an access switch and a terminal.

For the unicast communication service in the access network, the step of configuring the downlink communication link of the current service by the master server may include the following steps:

and a substep S11, the main control server obtains the downlink communication link information of the current service according to the service request protocol packet initiated by the source terminal, wherein the downlink communication link information includes the downlink communication port information of the main control server and the access switch participating in the current service.

In the substep S12, the main control server sets a downlink port to which a packet of the current service is directed in a packet address table inside the main control server according to the downlink communication port information of the control server; and sending a port configuration command to the corresponding access switch according to the downlink communication port information of the access switch.

In sub-step S13, the access switch sets the downstream port to which the packet of the current service is directed in its internal packet address table according to the port configuration command.

For a multicast communication service (e.g., video conference) in the access network, the step of the master server obtaining downlink information of the current service may include the following sub-steps:

in sub-step S21, the main control server obtains a service request protocol packet initiated by the target terminal and applying for the multicast communication service, where the service request protocol packet includes service type information, service content information, and an access network address of the target terminal.

Wherein, the service content information includes a service number.

And a substep S22, the main control server extracts the access network address of the source terminal in a preset content-address mapping table according to the service number.

In the substep of S23, the main control server obtains the multicast address corresponding to the source terminal and distributes the multicast address to the target terminal; and acquiring the communication link information of the current multicast service according to the service type information and the access network addresses of the source terminal and the target terminal.

If the streaming media server determines that the first data is to be sent to other individual devices, the streaming media server may forward the first data to other individual devices without performing conversion processing on the first data because the first data is obtained by encoding the individual devices.

Step 605, if the streaming media server receives third data sent by the video networking terminal through the video networking via the video networking server and determines that the third data is to be sent to the individual soldier equipment, the streaming media server converts the third data to obtain fourth data, and sends the fourth data to the individual soldier equipment through the WIFI network.

If the streaming media server receives third data sent by the video network terminal through the video network server, whether the third data are to be sent to the individual soldier equipment can be determined. For example, the third data may include an identification of the target device to be transmitted to, and the streaming server may determine whether the third data is to be transmitted to the video network terminal according to the identification. If the identification of the target device comprises the identification of the other video networking terminal, it may be determined that the third data is to be sent to the other video networking terminal; if the identification of the target device includes the identification of the individual device, it may be determined that the third data is to be sent to the individual device.

And if the streaming media server determines that the third data is to be sent to the individual soldier equipment, the third data is coded by the video networking terminal, so that the third data is data which is based on a video networking protocol and has a coding format supported by the video networking terminal, and the individual soldier equipment cannot directly process the third data.

Therefore, the streaming media server can perform conversion processing on the third data to obtain fourth data. The specific conversion process may include:

b1, the stream media server converts the third data into data based on internet protocol;

b2, the streaming media server sends the data based on the internet protocol to the transcoding server;

since the third data is data based on the internet protocol, the streaming server may convert the third data into data based on the internet protocol. And sending the converted data based on the Internet protocol to a transcoding server.

b3, the streaming media server obtains the data which is returned by the transcoding server and is transcoded based on the internet protocol data to obtain a format suitable for the individual soldier equipment to process, and the data is used as fourth data.

In the concrete implementation, the streaming media server converts the third data into data based on the internet protocol, then enters a transcoding process, and sends the data based on the internet protocol to the transcoding server. And the transcoding server receives the data based on the Internet protocol, transcodes the data based on the Internet protocol into the data in the format suitable for the processing of the individual soldier equipment when detecting that the coding format of the data is the format supported by the video networking terminal, and transcodes the data into the data in the coding format supported by the individual soldier equipment. Optionally, the transcoding server decodes the data with the coding format supported by the video networking terminal into corresponding PCM data, processes the PCM data, and codes the PCM data into data with the coding format supported by the individual soldier equipment.

Therefore, the fourth data is data based on the internet protocol and encoded in a format supported by the individual soldier equipment. And after the streaming media server obtains the fourth data, the fourth data is sent to the individual soldier equipment through the WIFI network.

If the streaming media server determines that the fourth data is to be sent to other video network terminals, the streaming media server may forward the fourth data to other video network terminals without performing conversion processing on the fourth data because the fourth data is encoded by the video network terminals.

The above process can be applied to video conference, audio conference and other scenes. For example, in an audio conference, the format of audio data supported by an individual device may be G711 format, G711 is an audio coding mode specified by the international telecommunication union (ITU-T), also called ITU-T G711; the format of Audio data supported by the video network terminal may be an AAC (Advanced Audio Coding) format, and AAC is a file compression format specially designed for sound data, and it adopts a completely new algorithm for Coding, which is more efficient. Therefore, if the individual soldier device is used as a speaking party, the streaming media server converts the audio data which is based on the internet protocol and is coded in the G711 format and is transmitted by the individual soldier device into the audio data which is based on the internet protocol and is coded in the AAC format, and then transmits the audio data to the internet of view terminal. If the video networking terminal is used as a speaking party, the streaming media server converts audio data which are based on the video networking protocol and coded in the AAC format and are sent by the video networking terminal into audio data which are based on the Internet protocol and coded in the G711 format and then send the audio data to the individual soldier equipment.

Step 606, if the streaming media server receives fifth data sent by the individual soldier equipment through the WIFI network, the fifth data is sent to the mobile commanding equipment.

In a preferred implementation, the method of the embodiment of the invention can also be applied to a mobile command car. On the mobile command vehicle platform located on the internet, mobile command equipment, a 4G router and an LTE gateway can be deployed, and a worker can carry CPE and individual soldier equipment. The individual soldier equipment can send the data of gathering to the mobile commander equipment.

Therefore, the individual soldier equipment can encode the acquired external data into fifth data and send the fifth data to the streaming media server through the WIFI network. The fifth data is data to be sent to the mobile commander equipment, and the streaming media server may determine to be sent to the mobile commander equipment according to the identifier of the target equipment included in the fifth data. The fifth data is data which is based on an internet protocol and has a coding format supported by the individual soldier equipment, and the mobile commander equipment can directly process the data of the type, so that the streaming media server can forward the fifth data to the mobile commander equipment without performing conversion processing on the fifth data.

After receiving the fifth data, the mobile command device can perform operations such as decoding and playing, data analysis and the like on the fifth data, so as to make a command strategy and the like according to an analysis result. For the specific process, those skilled in the art can perform related processing according to practical experience, and this is not discussed in detail in the embodiment of the present invention.

The embodiment of the invention solves the problem of network access of individual soldier equipment, and the network access mode is more flexible; meanwhile, the problem of interaction between individual soldier equipment and a video networking terminal is solved, and communication between the Internet and the video networking is realized.
