Evaluating the effects of peer localization on a BitTorrent-based P2P video-on-demand network

摘要

Video-on-demand (VoD) is a rapidly growing method for viewing and sharing video content over the Internet. However, video on demand consumes a significant amount of bandwidth, forcing content publishers and content delivery networks to examine approaches such as the use of peer-to-peer (P2P) technologies to assist in video distribution. We study the performance impact of a peer localization strategy aimed at limiting traffic exchanges between autonomous systems such as Internet service providers (ISPs) in a P2P VoD setup. Our findings suggest that peer localization may improve streaming performance while reducing network traffic crossing autonomous systems, potentially benefitting both users and providers, respectively.
