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.

In the embodiment of the invention, before entering the video conference, the virtual terminal dynamically configured for the mobile terminal by the monitoring access server can enter the video network only after the network access authentication is carried out on the network management server, and then the real-time data interaction can be carried out with the video network terminal.
Specifically, in the operation process of the video network, the video network core server always sends a broadcast packet, and the monitoring access server receives the broadcast packet of the video network core server after being started and starts to perform network access authentication. Each virtual terminal dynamically configured by the monitoring access server sends a handshake request to the network management server, the network management server judges whether the virtual terminal belongs to the virtual terminal in the network management server after receiving the handshake request, if so, the network management server replies a handshake response, and if not, the network management server does not reply the handshake response. The virtual terminal can subsequently continue to perform the network access authentication process based on the handshake reply.
In the embodiment of the present invention, the network access authentication request may refer to a verification request sent by the virtual terminal and used for connecting to the video network.
In this step, after receiving the handshake response of the network management server, the virtual terminal sends a network access authentication request to the network management server based on the handshake response. And the network management server authenticates after receiving the authentication request, if the authentication is passed, the network management server sends heartbeat inquiry to the virtual terminal, and if the authentication is not passed, the network management server does not send heartbeat inquiry to the virtual terminal any more so as to refuse the virtual terminal to access the network.
In the embodiment of the invention, when the virtual terminal receives the heartbeat query sent by the network management server, the virtual terminal is judged to pass the network access authentication at the moment and can be connected to the video network. The virtual terminal can reply the heartbeat to the network management server to realize the connection with the video network. Therefore, the mobile terminals participating in the training personnel access the video network based on the virtual terminal, and can participate in the subsequent video conference.
