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.

A monitoring and calling method is applied to a video network, and the video network comprises the following steps: the method comprises the following steps that a monitoring management platform, a shared server, a protocol conversion server and monitoring equipment are configured in the shared server, a plurality of video networking protocol addresses are configured in the shared server, each video networking protocol address corresponds to a plurality of sub-protocol addresses, the protocol conversion server sends video networking videos to the shared server according to the sub-protocol addresses, and the method comprises the following steps:

receiving a monitoring signaling sent by the monitoring management platform;

acquiring the idle subprotocol addresses according to the monitoring signaling, wherein the subprotocol addresses with the corresponding number are acquired according to the number of the monitoring equipment identifiers in the monitoring signaling, and the mapping relation between each monitoring equipment identifier and each subprotocol address is established;

receiving a corresponding monitoring video according to the subprotocol address;

receiving a heartbeat reply signaling sent by the cooperation server;

sending the heartbeat reply signaling to the monitoring management platform so that the monitoring management platform can judge whether the coordination server is on line or not;

after receiving the monitoring stop signaling sent by the monitoring management platform, the method further comprises:

2. The method according to claim 1, wherein after receiving the corresponding surveillance video according to the sub-protocol address, further comprising:

3. The method of claim 1, wherein after sending the monitoring signaling to the coordination service according to the sub-protocol address, further comprising:

4. A monitoring and retrieving device, wherein the device is applied to a video network, and the video network comprises: the device comprises a monitoring management platform, a shared server, a protocol conversion server and monitoring equipment, wherein a plurality of video networking protocol addresses are configured in the shared server, each video networking protocol address corresponds to a plurality of sub-protocol addresses, the protocol conversion server sends video networking videos to the shared server according to the sub-protocol addresses, and the device comprises:

the acquisition module is used for acquiring the idle subprotocol addresses according to the monitoring signaling, acquiring the subprotocol addresses with corresponding number according to the number of the monitoring equipment identifiers in the monitoring signaling, and establishing the mapping relation between each monitoring equipment identifier and each subprotocol address;

the receiving module is used for receiving the corresponding monitoring video according to the subprotocol address;

a fourth sending module, configured to send the heartbeat reply signaling to the monitoring management platform, so that the monitoring management platform determines whether the coordination server is online;
