Abstract: The improving of firewall performance raises the requirement of high performance benchmarking tool for evaluation. This article proposes a mapping algorithm which gives direct mapping between connection and storage index, and a structure which deals with the connections synchronously phase by phase, the performance of concurrent TCP connection emulation can be improved.
