Research on BitTorrent Bandwidth Model
BitTorrent带宽模型研究

Peer behavior in BitTorrent(BT)network is analyzed in detail,and the models related with peer behavior in- cluding file fragment model,interesting and choking model are presented.The probability of a peer interested in neigh- bor peer,the probability of a peer being choked by neighbor peer,and the probability of uploading peer being selected are analyzed.Based on these models and probability expression,the BT bandwidth model is evolved.
