MTorrent: A multicast enabled BitTorrent protocol
Piyush Agrawal, Hitesh Khandelwal, R. K. Ghosh · 2010
In this paper we address the problem of repetitive data transmission in BitTorrent. and propose a new protocol called MTorrent to restrict the same by exploiting IP Multicast functionality wherever available. A prototype system of our protocol have been implemented, and large scale measurement studies were conducted over Emulab network consisting of 44 nodes, spread over 9 LANs and 36 end clients. MTorrent leads to 44% reduction in download time, 65% reduction in traffic load on the Internet links and 40% reduction in download of redundant packets when compared to the BitTorrent. MTorrent is interoperable with BitTorrent, and requires only a few changes at the client end.
