提出的高速网络协议识别方案用FSM表示RegExp,用硬件完成模式匹配,实现了高速的网络协议识别,解决了基于软件的字符串匹配不能适应高速网络发展的问题。测试表明其模式匹配速度可达到Gbps以上性能。
This paper introduced a high-speed network protocol identification scheme,which used FSM to represent RegExp,implemented pattern matching by hardware,finally achieved fast protocol identification.It solved the problem of pure software implement which could't meet the performance requirement of high-speed link.The proposed scheme can operate at more than Gbps rate.
