Coral - The Coral P2P Content Distribution Network
http://www.coralcdn.org/

Coral is peer-to-peer content distribution network, comprised of a world-wide network of web proxies and nameservers. It allows a user to run a web site that offers high performance and meets huge demand, all for the price of a $50/month cable modem. Publishing through Coral is as simple as appending a short string to the hostname of objects' URLs; a peer-to-peer DNS layer transparently redirects browsers to participating caching proxies, which in turn cooperate to minimize load on the source web server. Sites that run Coral automatically replicate content as a side effect of users accessing it, improving its availability. Using modern peer-to-peer indexing techniques, Coral will efficiently find a cached object if it exists anywhere in the network, requiring that it use the origin server only to initially fetch the object once. One of Coral's key goals is to avoid ever creating hot spots in its infrastructure. It achieves this through a novel indexing abstraction we introduce called a distributed sloppy hash table (DSHT), and it creates self-organizing clusters of nodes that fetch information from each other to avoid communicating with more distant or heavily-loaded servers. Coral is not officially affiliated by New York University in any way. It instead was developed and is managed as a research project by the Secure Computer Systems group. Coral receives funding as part of the IRIS peer-to-peer research and development project, sponsored by the National Science Foundation. A preliminary deployment of CoralCDN has been online since March 2004. As of August 2005, it receives almost 20 million requests per day from about 750,000 unique clients.
