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.

When the monitoring system is started for the first time, the four video network television wall terminals receive the playing instruction sent by the monitoring scheduling platform, and then the four video network television wall terminals start to correspondingly play the first video network video data packets collected by the monitoring front end 1 to the monitoring front end 4. When the preset time is set to be 10 seconds, after 10 seconds, the four video-networking television wall terminals receive the polling switching instruction sent by the monitoring scheduling platform, then the first video-networking video data packets collected from the monitoring front end 1 to the monitoring front end 4 are stopped to be played, the second video-networking video data packets collected from the monitoring front end 5 to the monitoring front end 8 are started to be played correspondingly, after 10 seconds, the four video-networking television wall terminals receive the polling switching instruction sent by the monitoring scheduling platform again, then the second video-networking video data packets collected from the monitoring front end 5 to the monitoring front end 8 are stopped to be played, and the first video-networking video data packets collected from the monitoring front end 1 to the monitoring front end 4 are started to be played correspondingly. The circular playing is carried out in this way, and the purpose of round patrol is achieved.
In the embodiment of the present invention, one video network video wall terminal may also correspond to a plurality of monitoring front ends, and video network video data packets collected by the plurality of monitoring front ends may be sequentially played at preset time intervals according to the sequence, which is not limited in this embodiment of the present invention.
