Method for switching information of distributed multiprotocol proxy and center system

Abstract

A distributed multiprotocol proxy in the computer network technical field and method of exchanging center system message; in the present invention, a center and agent management model are constructed; the agent sends message exchanging form XML file to the center in which comprises an unique ID identifier distributed to the agent by the center; after the center verifies that the agent is legal, the agent and the center exchange the message through the XML file; the center monitors the state of the agent in real-time through the analyzing XML file sent by the agent, and processes protocol collection data at the late stage; the center sends the configuration file, management file to the agent through synchronous mechanism so as to realize the dynamic management to the agent. The present invention realizes the independency between the application protocol and message, the independency between the center and the agent, improves the mutual operation ability between the center and the agent, strengthens the safety, reliability between the center and the distributed agent communication, effectively and rapidly solves the problems of communication and cooperating between the center and agent framework.

Description

technical field [0001] The invention relates to a method in the technical field of computer networks, in particular to a method for exchanging messages between a distributed multi-protocol agent and a central system. Background technique [0002] In a complex network environment, due to different application environments, application purposes, and based on different application scenarios, there are different application layer protocols in the network, and the message formats of different protocols are different. The content obtained by the proxy analysis based on different protocols It is also different. The usual practice is to customize the interface between the agent and the center according to different protocols. However, if the protocol is very complicated and there are many application protocols in the network, this defined interface will become very complicated. The center gets from the agent. The message format is also complicated, which is not conducive to the unif...

Problems solved by technology

Its disadvantage is that the method and system are more valuable in improving the flexibility of the protocol analysis program, expanding and quickly implementing the protocol, but its function in terms of communication security is very weak, because the communication party only analyzes the received instructions but does not Verify whether the instruction is legal, which can easily cause malicious communication parties to forge or mistakenly send legal instructions to destroy or misoperate; its flexibility in protocol analysis procedures is still insufficient, because it does not uniformly format the XML format instruction script set, and It defines a limited command script library, which is not conducive to flexible expansion. For example, if there is a new communication requirement, a new command needs to be added, and the parsing code for the command needs to be added completely; The function is also very weak, and it is not suitable for the communication between the center and the agent, because it does not have a well-defined management cooperation mechanism, and it considers the peer-to-peer communication parties, without considering the difference between the center and the agent. There are also problems with many-to-many communication
