Abstract

Pure P2P applications are widely used nowadays as a file sharing system. In the overlay networks, music and video files are the main items exchanged, and it is known that the traffic volume is much larger than that of classical client/server applications. However, the current status of the P2P application traffic is not well known because of their anonymous communication architectures. In particular, in cases where the application does not use the default service port, and the communication route and the shared file are also encrypted, the identification traffic has not been feasible. To solve this problem, we have developed an identification method for pure Peer-to-Peer communication applications, especially for traffic for Winny, the most popular Peer-to-Peer application in Japan, by using server/client relationships among the peers. We will give some evaluation results for our proposed identification method.
