Abstract
Peer-to-peer (P2P) is promising for a new service to provide a scalable, robust, and flexible communication on the Internet. However, in the current implementations of P2P services, their communication quality is still insufficient. One of critical issues is that their logical topology constructions do not incorporate the underlying physical network characteristics. In this paper, we propose a new approach to build a logical network, takeing account of the physical network characteristics. First, we investigate the essential parameter for 'good' logic network construction of P2P service by traffic measurements and show method to derive suitable parameters. We also consider the control traffic to identify its influence. We finally propose the peer selection technique based on physical network measurement, and verify it via a simulation and measurement evaluation.
