Public Domain P2P File-Sharing Networks Measurements and Modeling

Since P2P file-sharing networks became extremely popular between Internet users, many researchers have tried to model those P2P networks. This article deals with the modeling of public domain P2P file-sharing networks in terms of some parameters such as their number of users and the number of files inside them along the time. To do so, we have been measuring five public P2P file-sharing networks (Gnutella, FastTrack, Opennap, Edonkey and MP2P) tracking their evolution for three years. The results will be discussed and compared with measurements taken from other authors. Results obtained could be used to design new P2P networks, to test their performance or to optimize P2P network's parameters
