As the Internet evolved, peer-to-peer networks became one of the major enabling technologies. Alternative solutions for several issues emerged with the use o this technology. Such is the case for the dissemination of large files to several receivers. The traditional client-server approach can not keep up with the rapidly increasing requests of the users. P2P file sharing networks came as an unconventional way of relieving the server from becoming the congestion point. The purpose of this paper is to show and analyze simulation results of an itinerary based algorithm for the dissemination of a highly anticipated file. Emphasis is given on several parameters of the network and how they can affect its performance.
