p4p application research oriented on multi-download service

Nowadays, the performance of p2p applications is limited by the network-oblivious peering and the scarcity of network resources, which leads to lots of wastes of networking resources and times. Hence, a light-weight architecture called p4p was proposed, it can control each p2p peers intelligently and achieve the goal of service optimization by reducing multi-download data transmission. In this paper, the performance of p4p is compared with several other optimization methods, the advantage of p4p framework is shown clearly in our evaluation results.
