A Study on Traffic Characteristics Evaluation for a Pure P2P Application
Satoshi Ohzahata, Konosuke Kawashima · 2008
Peer-to-peer (P2P) file sharing applications are widely used nowadays. In overlay networks, it is mainly music and video files that are transferred, and it is known that the traffic volume is much larger than that of classical client/server applications. However, the nature of current P2P application traffic is not well known because of the anonymous communication architectures used. To solve this problem, we have developed an identification method for pure P2P application traffic, especially for Winny, the most popular pure P2P file sharing application in Japan. Our method relies only on client/server relationships among the peers, without recourse to application header information. With using the method, we give an evaluation of the characteristics of the identified traffic collected in an ISP.
