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), and is defined to be 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 as follows: 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.

A pamir client, a conference control software client, typically runs on a user terminal.
And the virtual terminal is used for transparent transmission and is a bridge for communication between the pamir client and the autonomous server in a video networking mode.
The autonomous server is used for connecting a client based on the video network, forwarding information and processing internal services of the video network. The autonomous server and various video network equipment connected with the autonomous server form an autonomous cloud, the autonomous cloud is the minimum unit for video network operation, and compared with a conventional server, the autonomous cloud is a special server for video network.
The conference management scheduling server is a server side of conference control software and is used for processing a conference scheduling instruction and controlling and managing a conference management database.

The conference management scheduling server receives a first message containing a synchronization request and a user identifier, wherein the first message is generated by the pamir client and then forwarded to the conference management scheduling server through the virtual terminal and the autonomous server. When a video conference of a video network is executed, a pamir client is required to control the video conference, so that the pamir client is required to acquire corresponding video conference terminal information. The first message may be generated in a manner that after the user logs in the pamir client, a first message is generated every other corresponding preset time, and a synchronization request is sent to the conference management scheduling server, for example, the preset time may be 20 minutes, 40 minutes, 60 minutes, and the like, which is not limited in the embodiment of the present invention. Or after the user logs in the pamir client, a first message is generated immediately, and a synchronization request is sent to the conference management scheduling server, which is a specific first message generation method.
Step S602, in response to the synchronization request, obtaining target terminal information from a conference management database according to the user identifier in the first message.
