Fault tolerant peer-to-peer dissemination network

Abstract

The widespread use of broadband networks gave new ground for Peer-to-Peer systems. The evolution of these systems made P2P file sharing networks one of the most popular ways of sharing content. Due to their distributed nature, such networks tend to be a reliable source for highly anticipated files. However, along with the benefits of P2P networks, certain patterns became apparent. Uneven flow of data and intersperse congestion points could result on increased mean response time or even network failure. In this paper the structure of Peercast, an agent based dissemination network, is presented. Emphasis is given to the self organizing nature of the dissemination tree, and simulation results depict its behavior under strenuous conditions. © Springer-Verlag 2003.
