The P2P flows have occupied the dominating network bandwidth in current Internet and have increased the operation cost of ISP due to abundant flows between different ISPs. An important issue under research is how to make P2P be ISP-friendliness when they are competing with other applications. In this paper, we take BitTorrent as a popular P2P application example and propose a scheme based on ISP cooperation to improve locality of BitTorrent. This scheme confines the flows of BitTorrent inside ISP as many as possible to reduce the cost of flows between different ISPs. The simulation results of our prototype shows that this scheme reduces the load of the link between ISPs while it also decreases the download time of BitTorrent. This scheme can be used as reference to other P2P applications to deal with ISP-friendliness issue.
