• Over the past decade, the peer-to-peer (P2P) model for building distributed system has enjoyed indeble sucess and popularity, forming the basis for a wide variety of important internet applications such a file sharing, voice-over-IP (VOIP), and video streaming. This sucess has not been universally welcomed. Internet Service Providers (ISPs) and P2P systems, for example, have developed a complicated relationship that has been the focus of much media attention. While P2P bandwidth demands have yielded significant revenues for ISPs as users upgrade to broadband for improved P2P performace, P2P system are one of their greatest and costliest traffict engineering challenges, because peers establish connections largelly independent of the Internet routing. Ono [4] is an extension to a popular BitTorrent client that biases P2P conections to avoid much of these cost without sacrificing, and potentially improving, BitTorrent performance.
