In the last decade, le sharing systems have generally been dominated by P2P solutions. Whereas email and HTTP have been the \killer apps of the earlier Internet, a large percentage of the current Internet backbone trac is BitTorrent trac [15]. BitTorrent has proven to be the perfect le sharing solution for a decentralized Internet, moving the burden from central servers to each individual station and maximizing network performance by enabling unused communication paths between clients. Although there have been extensive studies regarding the performance of the BitTorrent protocol and the impact of network and human factors on the overall transfer quality, there has been little interest in evaluating, comparing and analyzing current real world implementations. With hundreds of BitTorrent clients, each applying dierent algorithms and performance optimization techniques, we consider evaluating and comparing various implementations an important issue. In this paper, we present a BitTorrent performance evaluation infrastructure that we are using with two purposes: to test and compare current real world BitTorrent implementations and to simulate complex BitTorrent swarms. Our infrastructure consists of a virtualized environment simulating complete P2P nodes and a fully automated framework. For relevant use, dierent existing BitTorrent clients have been instrumented to output transfer status data and extensive logging information.
