A BT Traffic Identification Method Based on Peer-Cache

摘要

In this paper, a method based on peer-information to control BitTorrent (BT) traffic in distributed model is proposed. It is called peer-cache method. Through recording and analyzing the peer-information which is obtained from the BT signaling traffic, the BT file-sharing traffic related witht hese peers can be accurately identified and controlled even it is encrypted. As more and more forcibly encrypted BT trafficis generated by the clients, our peer-cache method is more comprehensive than the popular port-based and signaturebased traffic identification methods.
