Experiences Building a Service Execution Node for Distributed IN Systems

We describe a Distributed Intelligent Network architecture. By laying a distributed processing environment a more flexible mapping between functional and physical entities is afforded. Mobile code can in turn be employed to cater for performance or load balancing considerations as well as to increase the overall flexibility and manageability of the system. Changes in the physical locations of the endpoints of a control relationship can be abstracted to higher layer software by virtue of the location transparency properties of the environment. We report on the development of an experimental implementation and we demonstrate how the aforesaid technologies improved its characteristics.
