Abstract: A method to realize the P2P network traffic classification based on the SVM is proposed.This method uses the network traffic statistical characteristic and SVM method based on the statistical theory to classify the different P2P traffic application.Mainly research focus on four kinds of network traffic classification,which are document sharing BitTorrent,media flows PPLive,network telephone Skype and immediate communication MSN.Introduce P2P traffic classification overall framework based on the SVM,describe how gain the traffic sample and the processing method,introduce the experimental result and construct the traffic classifier.The experimental results confirm the validity of proposed method,the average precise rate is 92.38%.
