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 present invention, the regional internet-of-view servers refer to servers configured for a certain region, and service regions between the regional internet-of-view servers do not overlap each other. For example, the first regional internet-of-view server may be an internet-of-view server configured for the beijing region, with which all terminals in the beijing region need to communicate when they need to access the internet-of-view. The second area video network server can be a video network server configured for the Xinjiang area, and when all terminals in the Xinjiang area need to access the video network, the terminals need to communicate with the video network server.
In order to realize cross-regional video networking live broadcast, the embodiment of the invention provides the bridging server which is connected with the video networking servers in different regions, and the bridging server can be communicated with the video networking servers in a plurality of regions.
The first area terminal is a terminal in the coverage area of the first area video network server, and the second area terminal is a terminal in the coverage area of the second area video network server.
When a first area terminal and a second area terminal need to access a video conference, a first area video network server accessed by the first area terminal sends a first conference number acquisition request to a bridge server, and a second area video network server accessed by the second area terminal sends a second conference number acquisition request to the bridge server.
The specific process of the bridge server receiving the first conference number obtaining request and the second conference number obtaining request can be described in detail with reference to the following preferred embodiments.
In a preferred embodiment of the present invention, the step 501 may include:
substep A1: the first Pamir software sends a first conference number acquisition request to the first area terminal, and the second Pamir software sends a second conference number acquisition request to the second area terminal.
In the embodiment of the invention, the first conference number acquisition request refers to a request of accessing the number of the video conference, which is required to be acquired by a first area terminal, and the second conference number acquisition request refers to a request of accessing the number of the video conference, which is required to be acquired by a second area terminal
The connection relationship between the respective devices may be: the first Pamir software-the first area terminal-the first area video network server-the bridge server, and the second Pamir software-the second area terminal-the second area video network server-the bridge server.

In a preferred embodiment of the present invention, the method may further include:
step C1: when the bridge server monitors that no conference number in an idle state exists on the first area video networking server side, the bridge server returns a first error code to the first area video networking server; and/or
Step C2: and when the bridge server monitors that no conference number in an idle state exists at the second area video network server side, the bridge server returns a second error code to the second area video network server.
In this embodiment of the present invention, the first error code is an error code sent by the bridge server to the first regional video network server when the first regional video network server side does not have a bridge server number in an idle state.
The second error code is an error code sent by the bridge server to the second regional video network server when the second regional video network server side does not have the bridge server number in the idle state.
And when the bridging server monitors that the conference number in the idle state does not exist at the first area video network server side, returning a first error code to the first area video network server.

After the bridge server sends the first conference number to the first regional internet-of-view server and the second conference number to the second regional internet-of-view server, step 504 is performed.
Step 504: the first regional video network server forwards the first conference number to first Pamir software corresponding to the first regional terminal, and the second regional video network server forwards the second conference number to second Pamir software corresponding to the second regional terminal.
After the first regional internet-of-view server receives the first conference number sent by the bridge server, the first regional internet-of-view server can forward the first conference number to the first Pamir software corresponding to the first regional terminal.
After the first and second regional video networking servers receive the second conference number sent by the bridge server, the second regional video networking server may forward the second conference number to the second Pamir software corresponding to the second regional terminal.
