A peer-to-peer(P2P) network is a distributed application architecture which provides many attractive features,such as availability,self-organization,load-balancing,and anonymity.However,P2P network has created significant problems to network operators by generating large volumes of inter autonomous system(inter-AS) traffic.Focusing on the BitTorrent swarming protocol,this paper proposes an approach which aims to reduce P2P generated inter-AS traffic.In particular,the approach can reduce inter-AS traffic by 50% to 70%.Moreover,it can improve the downloading speed by 60% for the popular torrents.The evaluation shows that controlled regional-based contents replication can effectively achieve this goal.Furthermore,the approach is incrementally deployable.Network regions in which the system gets deployed can solve their P2P generated inter-AS traffic problems autonomously,i.e.,without any Internet service providers-collaboration and any requirement,the system can be deployed in the entire Internet.

Future, the approach is incrementally deployable. Network regions in which the system gets deployed can solve their P2P generated inter-AS traffic problems autonomously, ie, without any Internet service providers-collaboration and any requirement, the system can be deployed in the entire I nternet.
