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 |
the Destination Address (DA) is composed of 8 bytes (byte), the first byte represents the type of the data packet (e.g. various protocol packets, multicast data packets, unicast data packets, etc.), there are at most 256 possibilities, 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 types of different datagrams, and is 64 bytes if the type of the datagram is a variety of protocol packets, or is 1056 bytes if the type of the datagram is a unicast packet, but 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 a Label of Multi-Protocol Label switching (MPLS), and assuming that there are two connections between a device a and a device B, there are 2 labels for a packet from the device a to the device B, and 2 labels for a 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.
Based on the above characteristics of the video network, one of the core concepts of the embodiments of the present invention is proposed, in which, following a protocol of the video network, the first video network node server sends the first request message to the third video network node server through the second video network node server to obtain the packet information of the virtual terminal managed by the third video network node server. After the first video network node server determines the target virtual terminal from the grouping information, the second video network node server sends a second request message to a third video network node server so as to acquire the video network number of the target virtual terminal. And the first video network node server adds the target virtual terminal to the video conference according to the video network number of the target virtual terminal.

The first video network node server can utilize the conference scheduling module to generate a first request message, and the first request message is used for acquiring the grouping information of the virtual terminals managed by the third video network node server.
In practical applications, the first video network node server may generate the first request message according to a preset packet request protocol by using the conference scheduling module. The packet request protocol may include a packet request identifier, a video conference identifier, a global video conference identifier, a packet identifier, and the like, and specifically, the packet request protocol may specifically include content items as shown in the following table:
since the first node server of the video network cannot know in advance that the virtual terminal managed by the third node server of the video network is divided into groups, the content item of the group ID is set to "-1" (besides-1, it may be a specified value), and the "-1" may be understood as that the first request message is used to acquire the group information of all the virtual terminals managed by the third node server of the video network.
After the first request message is generated by the first video network node server, the first request message may be sent to the second video network node server according to the video network protocol, and the second video network node server sends the first request message to the third video network node server according to the video network protocol.
In the embodiment of the invention, after receiving the first request message, the third node server of the video network can generate the packet information according to the first request message and the preset packet response protocol, and send the packet information to the second node server of the video network according to the video network protocol, and the second node server of the video network sends the packet information to the first node server of the video network according to the video network protocol. The packet reply protocol may include a packet reply identification, a video conference identification, a global video conference identification, a packet identification, a number of packets, a virtual terminal identification, a number of virtual terminals, and the like.
In a preferred embodiment of the present invention, the group information generated by the third internet-of-view node server may include group number information and group terminal information. The group number information indicates the number of the virtual terminals managed by the third node server of the video network divided into several groups, and the group terminal information indicates the detailed information of the virtual terminals included in each group. In practical applications, the third internet of view node server may generate the packet quantity information according to a packet quantity response protocol, which may specifically include the content items shown in the following table:

When the first node server of the video network generates the second request message according to the grouping information and the preset number request protocol, the second request message can be generated according to the terminal number and the number request protocol of the target virtual terminal in the grouping information. The target virtual terminal is a virtual terminal selected from the virtual terminals contained in the grouping information by the first video network node server in response to the selection operation of the user, and the target virtual terminal is a virtual terminal to be added to the video conference. The number request protocol may include an identifier of a conference entry request, an identifier of a video conference, an identifier of a global video conference, an identifier of a terminal number, and the like, and specifically, the number request protocol may specifically include content items as shown in the following table:
