Peer-to-peer (P2P) file sharing system such as BitTorrent performs better than traditional client-server system in "flash-crowd" scenario taking advantage of "perpendicular" bandwidth between peer nodes. However large amount of backbone bandwidth in the Internet is consumed by these ubiquitous P2P connections. In this paper, we propose centralized hierarchical peer-node assignment (CHPA) to globally manage P2P traffic by intentionally set up connections within local area network. Experiment result shows that: in our experiment environment, CHPA can achieve higher proportion of local area network traffic while download time of BT is not apparently affected.
