Active network approach for web caching

Web caching is an effective way to save network bandwidth and promote network performance. In traditional network, strong consistency and collaboration mechanism establishment are two major problems. AWC (Active Networking Caching) is a distributed service based on active network. Each cache traces of server and makes a virtual link between cache and server. Different servers can share their branch nodes, so AWC will cause fewer burdens than conventional solution. AWC provides a lightweight way to coordinate distributed caches. Cache nodes needn't communicate with other caches to share storage for the sibling cache nodes share their storage. It can reduce the cost of collaboration establishing. The simulation results shows AWC cost less network bandwidth for state tracking between server and caches.
