In the present network environment,P2P download software flow takes too much bandwidth with broadband access,which creates a huge consumption of network bandwidth.Therefore,it is necessary to detect and control P2P download flow.This paper puts forward a method of multi-stage and multi-protocol-based P2P flow recognition which has the ability of deep packet inspection.This method has many good qualities such as high recognition accuracy,high efficiency and high extensibility.Based on this method,an extensible and multi-protocol P2P traffic flow recognition sys-tem is designed in this paper.This system is designed in the form of layered and extensible plug-ins,and can identify P2P traffic flow based on differ-ent ki-nds of protocols efficiently and accurately.Experiments show that this system can identify P2P traffic flow with the accuracy rate of more than 99.90%.
