Problems solved by technology

Although the existing method prevents the proxy node from receiving the message sent by itself by searching and processing the ProxyNodeTable table, it still cannot avoid continuing to send the message that does not have the destination address to the network switching bridge connected to the RedBox. It is easy to cause excessive communication traffic of the network switching bridge

Abstract

The invention relates to an agent port communication flow control method and a redundant device. The agent port communication flow control method is applied to a redundant network including a plurality of redundant devices, wherein the method comprises the steps of: establishing an agent node exchange table; extracting first address information in a message sent by an agent node, and storing the first address information in the agent node exchange table; extracting second address information of a message received by a redundant port, and searching the agent node exchange table for the first address information corresponding to the second address information; and if the first address information corresponding to the second address information does not exist, then not sending the message received by the redundant port to the agent node port. According to the invention, the agent node exchange table is established, the source address corresponding to a target address is stored and searched in the agent node exchange table, and under the condition that the source address corresponding to the target address exists, the message is sent to a network bridge through the agent node, and the communication flow of the network bridge is effectively lowered.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a communication flow control method and redundant equipment of a proxy port. Background technique [0002] With the rapid development of my country's economy and the continuous improvement of industrial manufacturing levels, the machinery and equipment required for industrial production are becoming more and more advanced, and the degree of automation of the production process has been greatly improved, which makes the production process and equipment more complicated. Therefore, the safety of equipment Safety has also become extremely important. The safety control system can effectively avoid man-machine accidents during operation and ensure the safety of personnel and equipment. Safety control systems are widely used in chemical industry, coal, oil and gas and other industrial fields. [0003] At present, redundancy technology, one of the core technologies of industrial E...
