Abstract: | 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. |
