A trace study of BitTorrent P2P file distribution with downloading-side performance measurement and analysis

摘要

The peer-to-peer networking technologies and systems provide a rapid and scalable content distribution mechanism for the increasing client population to access an explosive volume of media files on the Internet. Whereas the BitTorrent protocol and its derivatives are the most popular peer-to-peer file sharing applications, this paper proposes the performance measurement and analysis of BitTorrent protocols with an extensive volume of real trace logs. This examination reveals many new characteristics and information into the virtue of BitTorrent protocols in terms of downloading-side metrics, including overall download time and download bandwidth utilization, which have not been well specified in prior works that mainly focused on system-oriented and uploading-side performance measurements.
