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.
