为了解决网络入侵检测系统在流量较大的情况下出现很高的丢包率的问题，设计出一种多媒体链表结构。该链表结构在传统链表基础上，通过增设多媒体类型结点将链表分解。能够对网络流量中已识别的各类多媒体数据快速处理，并对其进行预先检测，使安全的多媒体数据包越过网络入侵检测系统的常规检测过程。通过实验，在网络入侵检测系统中使用多媒体链表后，丢包率降低18％以上，对多媒体数据包的检测率有不同程度的提高。实验结果表明：使用多媒体规则链表可有效降低网络入侵检测系统的丢包率。

In order to reduce the high packet loss rate of the network intrusion detection system (NIDS) when the network traffic is high ,a multimedia list structure was designed in which the traditional rule list was decomposed by adding media type nodes to the rule list .This multimedia list can identify various types of multimedia packet in the network traffic and detect them in advance ,so that the secure multimedia packets can cross the course of routine detection by the network intrusion detection system . Experiments show that the packet loss rate of NIDS can be reduced over 18% by using this list .The detection rate of multimedia packets has increased to different degrees .The results suggest that the use of the multimedia rule list can effectively reduce the packet loss rate of NIDS .
