Eficiência de download em enxames BitTorrent.

Abstract

Nowadays, BitTorrent (BT) is the most popular file-sharing system. In this system, each file is distributed to a group of BT users called torrent. As we would expect, users and torrents have different characteristics, and these characteristics have some effects on the distribution of the file. For example, the users may have different bandwidths, while the torrents may have different population size. This work is based on the behaviour of about 80 thousand users sharing files in about 13 thousand torrents. All these users and torrents are used in order to investigate which characteristics have a significant effect on the quality of service experienced by the BT users.
