Experimental Views on Neighbor Selection in BitTorrent

Abstract

BitTorrent is a protocol for P2P content distribution, which has become an important Internet application in recent years. In this paper, we measure the performance of BitTorrent, explain its key elements, and analyze its efficiency. Our contributions are as follows: (1) present an effective way to measure the performance of P2P content distribution systems; (2) quantify Bit-Torrent's Neighbor Selection which impair its efficiency; (3) design a ShareStorm protocol which avoids the BitTorrent flaws. Our preliminary experiment shows that in terms of download time, ShareStorm outperforms BitTorrent by 50+%.
