			       ABSTRACT

This paper explores the Service Configurator pattern, which decouples
the implementation of communication services from their configuration.
This pattern increases the flexibility and extensibility of
communication services by enabling their configuration and
reconfiguration at any point in time without affecting other services.
The Service Configurator pattern is widely used in the system and
application programming environments including UNIX, Windows NT, and
Java.
