Peer-to-peer file sharing applications are major proportion of traffic in Internet. Among P2P file sharing applications, BitTorrent is known to be the most popular system, in which peers can download pieces of file proportional with upload bandwidth shared with others. Therefore, for such a system, bandwidth adjustment is very significant for peers. In this paper we aim at modeling this as a solution to an optimization problem which maximizes the portion of download bandwidth constrained by the average download time of peers. To solve this, we propose an iterative algorithm which can be implemented in a distributed manner with low computation and communication overhead.
