Data Distribution Algorithm of High-Speed Intrusion Detection system Based on Network Processor

Because the processing speed of intrusion detection system can hardly keep pace with the high-speed development of network, improving the speed of intrusion detection has been the problem starved for solve. By adopting the network processor, a distribution algorithm based on protocol analysis has been realized. By delivering the captured data package to each detect node according to protocol types and then accomplishing the detection for data package through the collaboration of the detect nodes, the processing efficiency of the intrusion detection system has been improved as a whole.
