3 Abstract Reduction of search packets by sharing peer information in P2P communication KIMURA Norio In recent years, the traffic on the Internet have been increasing rapidly and have caused several problems. The number of users, who use the three major peer-to-peer file sharing applications such as Winny, reaches 150, ,000, in the reports by research companies. Overlay networks are built to achieve efficient communication by P2P applications. However, when peers use more than one P2P application, each P2P application has to manage its overlay networks. Specifically, the P2P application has to renew overlay networks depending on peers behaviors such as participation to a network. In my proposal method, one overlay network is built and it is used by multiple P2P applications. By sharing this information of overlay network, it is possible to omit duplicated network participation processes of peers and it is possible to decrease traffic depending on network management. key words P2P, Overlay network ii
