A heartbeat mechanism-based instruction distribution system and method

Abstract

The invention discloses a heartbeat mechanism-based command distribution system and method, wherein the system includes: a server and a plurality of controlled terminals, wherein: the server is divided into a plurality of subnet areas according to the network address information of the controlled terminals, and each A subnet area randomly selects an online controlled terminal as a broadcast agent to communicate with the server at high frequency, and the server adds the controlled terminal list information that needs to obtain instructions in the heartbeat feedback information; When receiving command information from the network area, it broadcasts the terminal list information that needs to obtain the command; when the target host receives the broadcast, it initiates heartbeat communication with the server to complete the response to the command. It can improve the response efficiency of each controlled terminal in the heartbeat mechanism mode to the instructions issued by the server; combined with the way that the broadcast agent terminal communicates with high-frequency heartbeat and the controlled terminal communicates with low-frequency heartbeat, it effectively reduces the concurrency of the server load pressure.

Description

technical field [0001] The invention relates to the communication field, in particular to a heartbeat mechanism-based instruction distribution system and method. Background technique [0002] With the rapid development of science and technology, the network environment has become more and more complex, especially in the field of industrial control network. Due to the complexity of the network, users have higher and higher requirements for industrial control terminal security management products. Terminal security management products generally use one-way communication between the controlled terminal and the management terminal, that is, the terminal agent program periodically accesses the server to obtain management instructions, and then realizes server-to-terminal security policy configuration and other management. The mechanism of one-way communication between the control terminal and the management terminal is called the heartbeat mechanism. [0003] Based on the scenar...

AI Technical Summary

Problems solved by technology

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect in the prior art that when distributing instructions to a certain terminal, the time delay is relatively large, causing the server to fail to manage the terminal in time, which in turn leads to low response efficiency of management instructions , so as to provide a heartbeat mechanism-based command distribution system and method
