The reliability of protocol analysis and intrusion detection can be improved greatly by identifying application-level protocol and analyzing different protocols with different methods before protocol analysis and intrusion detection.

• 在进行协议分析和入侵检测以前首先对应用层协议进行识别并分别对不同协议采用不同的分析手段；可以极大的提高协议分析和入侵检测的可靠性.
