The system primarily uses the protocol analysis technology and mode matching arithmetic in realizing network engine . through the combination of the above two , it effectively monishes the target matching scope and improves the detecting speed 系统在实现网络引擎时，主要使用了协议分析技术和模式匹配算法，通过两者的结合，有效地减小目标的匹配范围，提高了检测速度。
