In this paper, the authors propose a modification to the BitTorrent protocol related to its peer unchoking policy. In particular, they apply a novel optimistic unchoking approach that improves the quality of inter-connections amongst peers, i.e., increases the number of directly-connected and interested-in-cooperation peers without penalizing underutilized and/or idle peers. The optimistic unchoking policy takes into consideration the number of clients currently interested in downloading from a peer that is to be unchoked. The conjecture is that peers having few clients interested in downloading data from them, should be favored with optimistic unchoke intervals.
