Performance analysis of peer-to-peer networks for file distribution

Ernst Biersack, Pablo Rodriguez & Pascal Felber

Résumé Peer-to-peer networks have been commonly used for tasks such as file sharing or file distribution. We study a class of cooperative file distribution systems where a file is broken up into many chunks that can be downloaded independently. The different peers cooperate by mutually exchanging the different chunks of the file, each peer being client and server at the same time. While such systems are already in widespread use, little is known about their performance and scaling behavior. We develop analytic models that provide insights into how long it takes to deliver a file to N clients. Our results indicate that the service capacity of these systems grows exponentially with the number of chunks a file consists of.
