Executive Summary

Peer-To-Peer (P2P) live streaming systems have been increasingly popular and successful in today's Internet, which provide large collections of video channels to millions of users at low server costs. The large volumes of P2P streaming traffic are exceeding those incurred by BitTorrent-like file sharing applications, threatening huge traffic relay cost to the Internet Service Providers (ISPs). There have recently emerged proposals advocating locality-aware P2P streaming protocol design, which aim to constrain streaming traffic within ISP boundaries and to alleviate traffic relay cost to the Internet Service Providers (ISPs). Nevertheless, there is a lack of in-depth understanding on the impact of such a locality-aware design on P2P streaming performance.
