| Research Abstract |
P2P applications impose an enormous traffic load on the Internet.Actually, however, topological difference between P2P network and underlying physical network (Internet network) is creating inefficient use of the physical network resources. To this problem, we proposed P2P download control methods using router network parameters (e.g., RTT , TCP window size and BGP path information) that can achieve effective use of router network resources, thus relieve ISP traffic burden and improve P2P application performance. Simulation results revealed the effectiveness of the proposed methods.
