BitTorrent is currently the dominant Peer-to-Peer (P2P) protocol for file-sharing applications.
BitTorrent is also a nightmare for ISPs due to its network agnostic nature, which is
responsible for high network transit costs. The research community has deployed a number
of strategies for BitTorrent traffic localization, mostly relying on the communication between
the peers and a central server called tracker. However, BitTorrent users have been
abandoning the trackers in favor of distributed tracking based upon Distributed Hash Tables …

… Which files should we localize? … • We design, prototype, and preliminary evaluate the
first traffic localization mechanism for DHT-based BitTorrent networks - Resource utilization
scales with the # of peers per torrents. - Can run on any machine with connection to the
Internet. - Issues with flawed protocol implementations. - …
