Network Intrusion Detection System (NIDS) is an important network security system. There always appears high packet loss rate in NIDS, especially when the network traffic is high. We raised Multimedia Packets Processing Method to reduce the packet loss rate and received good results. On this basis, Dynamic Programming is applied to optimize the decision-making steps of this method. This improvement can help the system to find an optimum solution to select the highest risk of multimedia data packet sequence in each time slice, moreover, the system load capacity can also be considered. In this way, the limited processing power of NIDS can be focused on the more dangerous multimedia data packets. A series of experimental results indicate this optimization can help the system to improve the detection rate of the high risk of multimedia information.

Research on A structure of the Multimedia list Oriented Network Intrusion Detection System

There always appears high packet loss rate in Network Intrusion Detection System (NIDS), especially when the network traffic is high. To address this problem, we have proposed the methods to identifying multimedia packets and processing them in a particular way thus received good results. On this basis, this paper propose a solution that uses a multimedia list structure based on the original list in NIDS. This multimedia list structure can let NIDS reduce the matching times to multimedia packets significantly by shortening the average searching length of OTN nodes dramatically. In addition, this paper also introduce the method of dynamic sorting to the multimedia list in order to shorten the time of rule matching. So this solution can further improve the detection efficiency of NIDS by speeding up the processing efficiency of NIDS to multimedia packets. Various experiments have shown that the packet loss rate of NIDS can be reduced on a large scale and the security of NIDS is not reduced by using the multimedia list.
