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.
Based on the above characteristics of the video network, one of the core concepts of the embodiments of the present invention is provided, and in the case of receiving the request list operation, the video network terminal may send a request list instruction including a target virtual terminal number to the video network server; the video network server stores a first corresponding relation between any one virtual terminal number and the identification information of a plurality of monitoring terminals and a second corresponding relation between the identification information and the communication information of the corresponding monitoring terminals; therefore, the video network server can determine a monitoring resource list comprising a plurality of communication information corresponding to the target virtual terminal number; the video network terminal can receive the monitoring resource list and determine a target monitoring terminal to be checked through a plurality of communication information corresponding to the target virtual terminal number; the video network terminal can send target communication information corresponding to the target monitoring terminal to the protocol conversion server, and the protocol conversion server receives video streams of the target monitoring terminal based on the video network, so that a user can select monitoring pictures to be watched through the video network terminal at any time, and the flexibility of video monitoring services under the video network is improved.

The video network terminal 40 may be a display device having an input device, or may be a computer having an input device; the video network terminal 40 can receive the request list operation sent by the input device and send a request list instruction to the video network server; the video network terminal 40 may also receive a monitoring resource list sent by the video network server, and receive a monitoring video stream sent by the collaboration server 20; the video networking terminal 40 may also present the surveillance video stream sent by the receiving collaboration server 20.

For example, a monitoring line selection interface in the video network terminal is opened through a remote controller, and at this time, the video network terminal sends a request list instruction to the video network server.
Further, the request list instruction includes a target virtual terminal number. The virtual terminal number is not the equipment number of any real video network terminal, but is an independent virtual number generated by the video network server. The target virtual terminal number is one of a plurality of virtual terminal numbers, and any one of the virtual terminal numbers can be transmitted as the target virtual terminal number. In the video network server, a first corresponding relation between any one virtual terminal number and the identification information of a plurality of monitoring terminals is stored. Specifically, the video network server may determine the identification information of the plurality of corresponding monitoring terminals according to one virtual terminal number and the first corresponding relationship.
Further, the identification information of the monitoring terminal may be a unique device number of the monitoring terminal, or unique identity identification information, and the like, which is not specifically limited in the embodiment of the present invention.
