Abstract: Traditional system architectures based on general purpose processor and ASIC can not satisfy requirements to high performance and flexibility of network information audit system. Taking IXP2400 for example, this paper researches the system architecture of network information audit system based on network processor, provides its implementation method and related key technologies. By using interface card ENP-2611 of Radisys company, its implements the proposed system, researches the high efficiency Chinese-English multi-pattern matching algorithm based on network processor. The experiment shows that the speed of proposed system is about 500Mb/s, which is higher than existing systems.

Key words: network information audit, network processor, IXP2400
