Unrevealing the Structure of Live BitTorrent Swarms: Methodology and Analysis
BitTorrent is one of the most popular applications in the current Internet. However, the authors still have little knowledge about the topology of real BitTorrent swarms and how the traffic is actually exchanged among peers. This paper addresses fundamental questions regarding the topology of live BitTorrent swarms. For this purpose they have collected the evolution of the graph topology of 250 real torrents from its birth during a period of 15 days. Using this dataset they first demonstrate that real BitTorrent swarms are neither random graphs nor small world networks. Furthermore, they will see how some factors such as the torrent popularity affect the swarm topology.
