Description

Communication protocol implementation method, device, network management server and storage medium

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for implementing a communication protocol, a network management server, and a storage medium.

Background

In the field of video networking, when an existing network management server manages video networking equipment, a binary protocol is generally adopted, specifically, the binary protocol adopts 2 bytes to represent a "command code", a plurality of bytes represent a "load", and different bytes correspond to different meanings.

When the protocol is extended, for example, a terminal mask and a heartbeat timeout function are newly set, and at this time, an extension load is required, a mask is newly added by 6 bytes, and a timeout is newly added by 4 bytes. Each time the protocol is extended, the network management server and the terminal are modified, if the network management server extends and modifies the communication protocol, and the terminal does not extend and modify the communication protocol, the network management server adopts the modified communication protocol to communicate with the terminal, and the terminal reports errors.

For example, if the terminal can only receive 10 bytes through the communication protocol, the network management server modified communication protocol sends 20 bytes; thus, the terminal cannot identify the data packet sent by the network management server.

If the network management server and the video networking equipment adopt binary protocol communication, the binary protocol communication is expanded and modified, the fixed bytes are required to be modified, the expansibility is poor, and the readability is poor.

Table 10

Wherein:

the total number of fragments of the message is more than or equal to 1; the "message current slice" is numbered from 1.

Message ID: the network management is responsible for filling when descending (network management to the visual network equipment), the original value is returned when the visual network server or the terminal responds, the value is increased at the network management side, the unique package id is represented, and the server or the terminal is responsible for filling when actively reporting,

When the server or the terminal actively reports, the single packet is filled with 0, and the server or the terminal is responsible for filling when dividing into multiple packets, the high four bytes of 0xFFFFFFFF is required, the low four bytes of the highest bit32 is 1, and each packet is guaranteed to be uniform.

CRC field, 2 bytes, adopts cyclic redundancy check method, the sender computer uses a certain formula to calculate a value of information contained in the transmitted data, and after attaching the value to the transmitted data, the receiver computer performs the same calculation on the same data, and the same result should be obtained. If the two CRC results are inconsistent, indicating that an error occurred in the transmission, the receiving computer may require the transmitting computer to retransmit the data;

application protocol data: application protocol data information in the form of KLV, i.e. KLV format, key-Length-Value, key representing the parameter identity, length representing the parameter Length, value representing the parameter Value. The advantage of adopting this format, the communication both sides, have one side not know this Key, neglect directly, need not to handle, the interface is unlikely to fail, increase flexibility.

TABLE 11

The application protocol data is application protocol data information of the KLV or application protocol response information of the KLV form.

Illustratively, the network management server sends a query instruction to the video networking terminal:
