Improvement of Upload Fairness for P2P Streaming
Satoshi Nakashima, Miki Yamamoto (Kansai Univ.)
Abstract (in Japanese) (See Japanese page) 
(in English) P2P streaming system, such as PPLive and PPstream, is constructed based on the widely deployed BitTorrent P2P system. In BitTorrent, Tit for Tat strategy is used for choking algorithm in order to deal with free rider problem. However, in P2P streaming system, another strategy of unchoking the most uploaded peers is applied because smooth distribution of
streaming chunks among peers is very important especially for streaming service. Peers whose offset is going ahead has more chunks to be exchanged than peers with lagged offset, which may lead to imbalance of upload among peers. In P2P system, all peer obtain almost the same amount of information, so fairness of upload amount among peers is one of the most important technical issues. In this paper, we propose a new choking algorithm where each peer tries to select peers with closest offsets
as unchoking peers. Our simulation results show that our proposed algorithm boosts chunk exchange among peers with close offsets, which greatly improves fairness among upload of peers.
