Abstract
With the explosive growth of demand for services on the Internet, the networking infrastructure (routers 7 protocols, servers) is under considerable stress. Mechanisms are needed for current and future IP services to scale in a client transparent way. We present HYDRANET, an infrastructure that allows one to dynamically replicate IP services by placing service agents (caching agents, mirrors, replicas) that are under the server's control at strategic points in the internetwork. HYDRANET is based on replicating transport level service access points (TSAPS) for transparent distribution or replication of IP services. Measurements on a local testbed show that the overhead of our scheme is small. TSAP replication is widely applicable. We use HYDRANET to implement active Web Caching and highly fault tolerant servers. Similaxly, it can be used to implement application gateways, for example intelligent multicast reflectors for media-on-demand.
