PeerDetecetor:a Link Model Based P2P Stream Detection Algorithm
Based on NetFlow technologies,we propose a model algorithm PeerDetector based on connection traffic detection.PeerDetector could detect the P2P traffic effectively from the local network.PeerDetector algorithm first detected HTTP traffic with HTD algorithm,then designed PTD algorithm to distinguish the P2P network traffic and traditional application traffic based on one-way characteristic of P2P connections,detect P2P traffic.Design and implement the algorithm and database,build a simulation test bed with the Dynamips Cisco router.Through laboratory tests.P2P traffic detection tool works well,which can effectively detect the majority of P2P traffic,the probability of false detection and the probability of failure is very small.
