Design of high-performance session management module in network behavior inspection system

Network management system is required to have highperformance as well as good functionality since the Internet traffic is increasing rapidly. This paper presents a design of network behavior inspection system based on PowerPC network processor and embedded Linux. To ensure the high performance of the system, the implementation of the session management module is based on the table lookup unit (TLU) of the network processor. Experimental result shows there is a substantial increase in the efficiency of the session management.
