We focus on the problem of enabling video-on-demandservices on the Internet. We propose a cost-effective solutioncalled Caching Agent, an overlay architecture consistingof caching servers placed across the Internet. Un-likeconventional proxies, these caching servers act asapplication-layer routers and cleverly cache data passingby. When a client's request encounters a cache miss at thelocal agent, this request may be satisfied by another nearbyagent without consuming any server bandwidth. This strategysignificantly alleviates the bottleneck at the server. Furthermore,since the full content is usually obtained fromsome agent instead of from the server which is usually over-loaded,Caching Agent results in a better service delay incomparison with conventional proxy schemes designed forvideo on demand.
