Peer-to-Peer (P2P) file-sharing accounts for an astonishing volume of current Internet traffic. Therefore, modeling and analyzing P2P file-sharing system to increase its understanding is significant and instrumental for the design and evaluation of new systems. In this paper, we firstly characterize and categorize the different types of P2P architecture. Secondly, we develop an analytic model for evaluating the performance of P2P file-sharing application in terms of user-perceived QoS and impact on the underlying physical networks. Thirdly, the tradeoff between the two most important metrics is weighed and some crucial parameters are abstracted and analyzed. Lastly, the locality-awareness to save potential bandwidth is presented and analyzed as well.
