Beehive: CobWeb
CobWeb is a next-generation content distribution network that can deliver web pages quickly to clients through a peer-to-peer cache. It uses the Beehive replication framework to provide a high performance web hosting service while consuming near-minimal storage and bandwidth at each participating node.
CobWeb operates as a ring of cooperative caching proxy servers, each of which is capable of serving any HTTP request. When web objects are requested, they are fetched from their origin servers and inserted into the system. Through an analysis of web object popularity, size, and update rate, CobWeb then computes an optimal replication strategy for each object to provide low lookup latency.
CobWeb is available for public use. On the server side, directing HTTP requests from your servers to CobWeb can reduce bandwidth demand on your servers, protect against flash crowds, and help alleviate denial of service attacks. On the client side, directing HTTP requests from your browser through CobWeb will speed up web surfing.
