TY - CHAP N1 - Global Telecommunications Conference, held in St. Louis (USA), 28 Nov.- 2 Dec. 2005 AV - none SN - 0-7803-9414-3 EP - 989 ID - eprints2560 N2 - BitTorrent is today one of the largest P2P systems which allows file sharing for Internet users. Very little effort has been dedicated to this target up to now. The goal of this paper is to develop an analytical model of a free-rider in a BitTorrent network. Unlike previous analytical models which capture the behavior of the network as a whole, the proposed model is able to analyze the performance from the user perspective. The model is applied to a case study to evaluate performance in a real case, and to obtain some insights into the influence of BitTorrent parameters on system performance.
