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.

The background service can be in communication connection with the collaboration server. The background service can acquire the monitoring equipment list from the cooperative server through the internet and store the monitoring equipment list into the database. Because the monitoring devices may change, such as whether to delete the monitoring devices, whether to add new monitoring devices, and the like, and the corresponding monitoring device list also changes, the background service may periodically synchronize the monitoring device list in the collaboration server so as to update in time.

Of course, the first video network header may further include information such as a video network number of the streaming media server, a video network number of the protocol server, and related information of the video network protocol, such as information such as an internal operation code of the video network protocol.
Step 503, the streaming media server sends the video networking protocol request packet to the protocol conversion server through the video networking via the video networking server.
The streaming media server sends the converted video networking protocol request packet to the video networking server through the video networking, and then the video networking server forwards the video networking protocol request packet to the protocol conversion server.
In an alternative embodiment, the video networking server may send the video networking protocol request packet to the protocol conversion server over a downlink communication link configured to the protocol conversion server.
In practical applications, the video network is a network with a centralized control function, and includes a master control server and a lower level network device, where the lower level network device includes a terminal, and one of the core concepts of the video network is to configure a table for a downlink communication link of a current service by notifying a switching device by the master control server, and then transmit a data packet based on the configured table.
Namely, the communication method in the video network includes:
and the master control server configures the downlink communication link of the current service.
