Abstract
The exponential growth of the use of the Internet has hics. caused increasing stress on the networking infrastructure. Routers, servers and protocols are reaching their limits and need room to scale up their capacities to meet user demands. Client-transparent techniques are needed to make servers scalable on demand. We have developed an enhancement to the TCP/IP infrastructure, called HYDRANET, which will enable servers to dynamically instantiate active agents at selected hosts (Replication Servers) in the Internet. These agents will replicate the transport-level service access points of their origin servers and begin serving clients in the name of the origin server. A new protocol and application API was also developed that manages this service replication scheme by allowing servers to connect to a Replication Server and instantiate a replica. We have applied this new method to a simple HTTP server to demonstrate push- based Web caching. Performance measurements have shown that the scheme does not incur severe penalties to access latency when deployed and actually improves local performance.
