Abstract

The method adopts application specific IC based on lookup table to extract and analyze packet header information. It includes following steps: 1) after the packet is analyzed and extracted according to packet header position and information extraction operation table, the key word of data packet is generated; 2) after completing the analysis and extraction of data packet, according to the generating rule of looking up key word the lookup key word is generated. The invention can modify analysis method for packet and define new processing method for type of protocol header by modifying relevant content of rule list.

Description

technical field

[0001] The invention belongs to the field of network communication system and application technology, and specifically relates to a data packet analysis and information extraction method, which is suitable for processing data packets in network devices such as network processors, routers, and switches. Background technique

[0002] As the scale of the Internet continues to grow, there are more and more services. Due to the increasing network data traffic, network equipment is required to have efficient and fast data packet analysis and processing technology to provide users with reliable services.

[0003] Currently, there are mainly two methods for analyzing network data packets. One is to adopt the software processing mode, and its basic idea is based on the multi-simple instruction set CPU architecture mode, which is composed of multiple peer CPUs, and different programs are written for it according to the design requirements to complete different functio...
