super server

A super server (sometimes also called "super daemon") is a daemon (= UNIX server process) that waits for connections on the ports of various server programs and starts the corresponding server when a connection is made. This way, there is only one server process for a set of services (instead of one for each service), but each service in the set is available to its clients.

The most common super servers are inetd (the "InterNET Daemon" that comes with many UNIX installations) and xinetd (the "eXtended InterNET Daemon").
