Peer-to-peer systems have become synonymous with file-sharing systems. Much of the focus of research in this area has been on providing algorithms to improve the efficiency, robustness, and security of routing in peer-to-peer systems, or designing services such as indexing and search for use by file-sharing applications running on these systems. There has been less focus on discovering new applications or enumerating the characteristics of applications for which peer-to-peer systems provide a viable, if not the only, solution.
The purpose of this talk is to show that peer-to-peer is more that just (illegal) file-sharing. I will review the definition of peer-to-peer and describe a set of characteristics of applications for which peer-to-peer systems are a necessary solution. I will then describe two example applications: LOCKSS, a peer-to-peer digital preservation system, and Blossom, a decentralized peer-to-peer approach to overcoming systemic Internet fragmentation.
