Abstract

Peer-to-peer content distribution is currently one of the main sources of traffic on the Internet. In spite of the extreme popularity of systems like BitTorrent, only a little attention has been paid to such systems in the research world. We believe one cause behind this lack of attention is the lack of suitable tools. Peer-to-peer content distribution aims at extremely large systems, consisting of several thousands or even millions of peers, which makes simulation a logical choice in studying them. In this paper, we present ChunkSim, a simulation framework for investigating peer-to-peer content distribution. We identify the key functionality of a peer-to-peer content distribution system and have implemented these requirements in ChunkSim. Furthermore, ChunkSim is an extensible framework and we demonstrate how it can be extended and discuss some common extensions.
