Components of HYDRANET
Host Servers: These are hosts that are specially equipped to host server programs from other hosts. These programs run under the IP address of their origin host. Host servers then become servers-of-servers.
Redirectors: These are specially modified routers that requests to services that are replicated. If the service is replicated, the message is redirected to the nearest host server with a replica of the service.
Replication Management Protocol: This protocol allows servers to dynamically install or tear down replicas on host servers.
