Abstract

A plethora of locality-aware BitTorrent (BT) protocols have been proposed to mitigate cross-ISPs traffic and maintain comparable downloading performance as native BitTorrent. However, very limited effort has been paid to theoretically analyze locality-aware BitTorrent protocols, which may potentially make them limited significance for Internet traffic controlment. In this paper, aiming at providing a fundamental understanding of locality-aware Bit-Torrent protocols, a general analytical framework was proposed to analyze downloading performance of a large family of locality-aware BitTorrent protocols. Theoretical analysis and network measurement were carried out to quantify the metrics and properties of the analytical framework.
