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:

DA

SA

Reserved

Payload

CRC

wherein:

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 datagrams, and is 64 bytes if the datagram is various types of protocol packets, and is 32+1024 or 1056 bytes if the datagram is a unicast packet, of course, the length is 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:

DA

SA

Reserved

label (R)

Payload

CRC

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.

Internet terminals (such as PC terminals, mobile terminals, etc.) generally process audio and video data based on internet protocols, and internet protocol packets of audio and video sent by the internet terminals can be transmitted in the video network only after being converted or re-encapsulated into video network protocol packets by the video network protocol. According to the embodiment of the application, the virtual terminal is accessed into the video network communication system by simulating the video network virtual terminal at the internet terminal, so that the virtual terminal can communicate with the video network entity terminal, and the internet terminal can send data to the video network communication system through the simulated virtual terminal without converting an internet protocol into a video network protocol.

Referring to fig. 5, fig. 5 is a flowchart illustrating steps of simulating to obtain a virtual terminal according to an embodiment of the present application.

The Internet terminal simulates to obtain a virtual terminal with an MAC address, and completes registration in the sub-control server, and the method comprises the following steps:

step S51: the Internet terminal runs a program and simulates a video networking terminal to obtain the virtual terminal;

the virtual terminal has the same function as the video networking entity terminal, can collect data, and can also perform operations such as encoding, decoding, packaging and the like on the data. Taking audio data and video data as an example, the virtual terminal can acquire the audio data and the video data through the PC end interface, encode the audio data and the video data, package the audio data and the video data into a video networking protocol packet, send the video networking protocol packet to a video networking communication system, and forward the video networking protocol packet to the entity terminal through the video networking server; the virtual terminal can also receive the video networking protocol packet of any audio data and video data of the video networking communication system, extract the audio stream and the video stream therein and play the audio stream and the video stream; the virtual terminal can also simulate audio streams and video streams, send the audio streams and the video streams to a video networking communication system, and perform scene testing to detect whether the entity terminal works normally or not.

Any internet terminal running program can be used for virtualizing one or more virtual terminals.

Step S52: and the Internet terminal configures the MAC address of the virtual terminal through the configuration file of the program, and then sends the MAC address to a sub-control server to complete the registration of the virtual terminal in the sub-control server.

The program can be a designated application program running on a PC terminal or an android mobile terminal, when the application program is initialized, a user inputs a configuration number in a designated format, and the application program configures the MAC address of the virtual terminal through a pre-stored configuration file. Where the configuration number cannot be repeated.

The internet terminal can send the configured MAC address to the sub-control server by any existing method, and the sub-control server records the MAC address of the current virtual terminal to complete the registration of the current virtual terminal.

The sub-control server is used for managing the entity terminals or the virtual terminals of each link in the video network communication system and sending the data sent by the entity terminals or the virtual terminals to other entity terminals or virtual terminals according to the corresponding links.

Referring to fig. 6, fig. 6 is a flowchart illustrating steps of a video networking access method according to an embodiment of the present application. Based on the above characteristics of the video network, one of the core concepts of the embodiment of the present application is provided, and in the existing video network communication system, the entity terminal and the virtual terminal obtained by the simulation of the internet terminal running program do not have communication connection, so the embodiment of the present application firstly completes the video network access of the virtual terminal.

The method is applied to a video networking communication system, and the system comprises the following steps: the method comprises the following steps that the method comprises the following steps of:

the main control server is used for managing the link state of the link in which each entity terminal or virtual terminal is positioned. Aiming at a link between each entity terminal or each virtual terminal, the video network master control server respectively detects the data flow of each node contained in the link; determining whether each node receives a data stream sent by an entity terminal or a virtual terminal; and determining the link state of the link according to the determination result corresponding to each node.

The entity terminal can be a starting terminal, an aurora terminal and other products.

Step S61: the Internet terminal simulates to obtain a virtual terminal with an MAC address, and the virtual terminal finishes registration in the sub-control server;

step S62: the sub-control server broadcasts a network access instruction, and the network access instruction carries the MAC address of the virtual terminal;

step S63: the virtual terminal receives the network access instruction, judges whether the virtual terminal is a target virtual terminal according to the MAC address, and responds to the network access instruction when the virtual terminal judges that the virtual terminal is the target virtual terminal;

the sub-control server broadcasts the network access instruction one by one according to the MAC addresses of all the virtual terminals stored locally.

After the virtual terminal receives the network access instruction, detecting an MAC address carried by the network access instruction, and if the MAC address is the MAC address of the virtual terminal, returning a response instruction to the sub-control server; if the MAC address is not the MAC address of the virtual terminal, the network access instruction is forwarded to other virtual terminals, or the network access instruction is directly ignored.

Step S64: after receiving a response instruction returned by the target virtual terminal, the sub-control server reports the response instruction to the main control server;

step S65: the master control server receives the response instruction and sends the heartbeat to the target virtual terminal, and the target virtual terminal receives and maintains the heartbeat;

and the sub-control server receives the response instruction returned by the target virtual terminal, confirms that the target virtual terminal is added into the link layer of the sub-control server, and reports the response instruction returned by the target virtual terminal to the main control server.

The virtual terminal accessed to the video network communication system can always maintain the heartbeat sent to the local by the master control server, and if the heartbeat stops, the virtual terminal is disconnected from the video network communication system.

Step S66: and the target virtual terminal maintaining the heartbeat sends a service request to the master control server, and the master control server returns a response of the service request so as to enable the target virtual terminal to be accessed into the video network and realize communication with the entity terminal.

After the virtual terminal is successfully accessed to the video networking communication system, permission for transmitting data through the video networking communication system also needs to be obtained. The virtual terminal directly sends a service request to the master control server, the master control server opens a channel for the virtual terminal to transmit data in the video network communication system, and returns the response condition of the service request to the virtual terminal, so that the purpose that the virtual terminal communicates with the entity terminal in the video network communication system is achieved.

The virtual terminal and the physical terminal can communicate through the video network communication system, but the data formats of the virtual terminal and the physical terminal are different, so that the physical terminal or the virtual terminal receiving the data packet needs to identify the sending terminal of the data packet.

The target virtual terminal maintaining the heartbeat can send and receive data in the video networking communication system, and the data format of the target virtual terminal is different from that of the entity terminal; the method further comprises the following steps:

The method further comprises the following steps:

The virtual terminal and the entity terminal process data based on a video networking protocol, and the data packet formats of the virtual terminal and the entity terminal both need to follow the relevant definition in the video networking protocol format description, so the formats of the video networking data packet sent by the virtual terminal and the video networking data packet sent by the entity terminal are different, however, the definition content specifically relates to the definition of the video networking transmission protocol common header and the multicast protocol header, so the terminal receiving the data packet can identify the sending terminal of the data packet through the video networking transmission protocol common header, and can detect whether packet loss occurs through the packet sequence number in the multicast protocol header.

Specifically, taking the example that the terminal receiving the audio/video data packet is an entity terminal, the method for identifying the sending terminal of the data packet is described in detail.

The common header values and packet lengths of the data streams may be as shown in the following table:

data stream type	Common header value	Packet length
			Entity terminal video stream	40018001	1078
Physical terminal audio stream	40024001	310
			Virtual terminal video streaming	48018002	1078
Virtual terminal audio stream	48004002	310

The entity terminal receives the audio and video data packet, extracts the common header value of the data packet, if the common header value of the data packet is 48018002 and 48004002, the sending terminal of the current audio and video data packet is a virtual terminal, and at the moment, the entity terminal converts the format of the received audio and video data packet into the data processing format of the entity terminal and then performs data processing;

if the common header values of the data packets are 40018001 and 40024001, the sending terminal of the current audio/video data packet is an entity terminal, and the entity terminal directly processes the received audio/video data packet at the moment.

When the terminal receiving the audio/video data packet is a virtual terminal, the processing method is similar to the above method, and details thereof are not described in the embodiments of the present application.

Obviously, the sending terminal of the audio and video data packet needs to add a data packet common header value to the audio and video data packet to be sent, so as to facilitate the identification of the receiving terminal of the audio and video data packet on the current audio and video data packet.

The common header value added by the virtual terminal to the audio data packets is 48004002, and the common header value added to the video data packets is 48018002; the common header value added by the entity terminal to the audio data packets is 40024001 and the common header value added to the video data packets is 40018001.

In practical application, the virtual terminal accessed to the video network communication system can also simulate audio streams and video streams and send the audio streams and the video streams to the entity terminal, and the entity terminal judges whether the entity terminal can continuously receive the audio streams and the video streams simulated by the virtual terminal or not in a mode of identifying the packet sequence number at the entity terminal of the entity terminal, so as to perform scene test on the communication quality of the entity terminal in the video network communication system.

The method further comprises the following steps:

The preset filling algorithm related to the embodiment of the application can support a pseudo-random mode and an incremental mode.

Incremental mode: the value of the first byte is the sum of the last two bytes of the packet sequence number, and the values of the following bytes are sequentially increased. The result of each calculation is modulo 256.

Referring to fig. 7, fig. 7 is a schematic diagram of an algorithm of a pseudo-random pattern according to an embodiment of the present application. Using the pseudo-random algorithm generator polynomial shown in fig. 7, a pseudo-random bit stream with a cycle length of 1048575 may be produced.

For example, A, B carries out video conference twice, first connects the entity terminal and the internet terminal to the video network, then runs the program of the internet terminal to obtain the virtual terminal, after the virtual terminal is successfully accessed to the current video network, simulates continuous audio stream and video stream, and sends the audio stream and video stream to the entity terminal to complete A, B scene test before video conference twice.

If the analog audio stream and the analog video stream received by the entity terminal are continuous, it indicates A, B that the video networking communication system of the two places passes the scene test and the video conference can be normally performed.

In specific implementation, the entity terminal may detect whether packet loss occurs through a packet sequence number in a "multicast protocol header" to determine whether the received analog audio stream and the analog video stream are continuous.

In practical application, the virtual terminal can also open an internet terminal to collect and store local audio data and video data, and encapsulate the audio data and the video data into a video networking protocol packet, and send the video networking protocol packet to the entity terminal for playing at the entity terminal.

The method further comprises the following steps:

In the prior art, if an internet terminal needs to send audio data and video data stored locally to a video networking entity terminal, the audio data and the video data need to be sent to the video networking entity terminal through a video networking communication system after being converted by an internet protocol and a video networking protocol.

In the embodiment of the application, the virtual terminal simulated at the internet terminal can directly open the audio data and the video data locally stored at the internet terminal, and encapsulate the audio data and the video data into the audio data packet and the video data packet of the video networking protocol, and directly send the audio data and the video data to the entity terminal, so that the audio data and the video data locally at the internet can be more conveniently transmitted to the video networking entity terminal for playing.
