Efficient Connection Management Method Based on TCP Three-way Handshake Characteristic

To promote the performance of packet processing and analysis in high-speed network, this paper proposes an efficient connections management method, Establishing Connection Buffering(ECB), in virtue of the characteristics of the three-way handshake in Transmission Control Protocol(TCP). Based on the analysis of TCP connection establishment process in IP network, it presents the design methodology that isolates establishing connections from whole connection table and buffers it separately. As a further step, it classifies packets into several types and gives the implementation of connection management for each type. It evaluates the performance of the ECB connection management with real high-speed network traffic trace. Experimental results indicate that the ECB performs almost 50% better than the traditional one with single connection table in terms of lookup performance.
