Abstract

Peer-to-Peer(P2P) applications such as BitTorrent and Coolstreaming ignore inter-AS traffic costs at ISPs and generate a large amount of cross ISP traffic. As a result, ISPs always restrict the BT application to control the inter-AS traffic cost. In this paper, we designe a new locality-awareness selection approach: multi-metric neighbor selection algorithm, to enhance local traffic. Based on pwhois query, the algorithm selects the neighbors within the same AS and district as source peers, and uses roulette method based on link bandwidth and latency to choose the final partner peers. Redundancy traffic calculation were implemented to prove the effectiveness of our approach. We evaluate two widely deployed P2P system: BitTorrent and CoolStreaming, under the real dataset from PlannetLab in our evaluations. The results demonstrate our algorithm effects both improving the download time and reducing the inter-AS traffic. Further more, the network congestion can be eased under our algorithm.
