Abstract

The invention provides a parameter acquiring and general protocol analyzing method and device. The method comprises the steps of: obtaining a message to be analyzed; according to a preset state jump table, carrying out regular expression matching on the message to be analyzed to obtain a state number corresponding a matched matching rule and position information of characters; and obtaining a matching rule corresponding to the state number according to a preset rule pairing table, and outputting a required field according to the matching rule and the position information and the cached message to be analyzed, wherein the matching rule is a starting point subrule or ending point subrule. The embodiment of the invention can realize general analysis on protocols.

Description

technical field [0001] The invention relates to network communication technology, in particular to a parameter acquisition and general protocol analysis method and device for general protocol analysis. Background technique [0002] In the network, the two communicating parties communicate based on standard protocols. Network protocol analysis refers to the analysis of the protocol header and tail of network data packets through programs, so as to understand the behavior of information and related data packets in the process of generation and transmission. In essence, the communication process between the two parties in the network communication is a process of analyzing the network data packets according to the standard protocol. Protocol analysis of network devices is usually performed based on a protocol stack. The protocol stack is a layered analysis system. After each layer processes the corresponding header, the header data is stripped and delivered to the upper layer...
