Peer-to-Peer Overlay Networks. Members: D. Hoang, H. Le, A. Simmonds

Peer-to-peer systems can be characterized as distributed systems in which all nodes have identical capabilities and responsibilities and all communication is symmetric. Traditionally, user?s PCs at the edges of networks can only play a role of clients, and never considered a role of servers that can provide services to other network users. Napsters, Freenet, Gnutella change all that; they represent a new step in distributed information systems. They allow PCs at the edges of networks to act as peers and hence these PCs can contribute an enormous amount of resources for storing information in a distributed manner and provide services. Each peer-to-peer system is a system for searching for information; each returns the information without telling you where it came from.

There are currently many projects aimed at constructing peer-to-peer applications. One of the key problems in large-scale peer-to-peer applications is to provide efficient algorithms constructing overlays for peer-to-peer systems.

This project aims to develop algorithms for constructing overlay structures that are dynamic and scalable to deal with transient nature of peer nodes, and that provide adequate quality of service for applications.
