Development of B-ISDN intelligent network service simulator

Multimedia telecommunication services will have a bright future for ATM networks. Many of them will need multipoint connections, and also will have to manipulate connections for a multimedia service. On the other hand, intelligent network architectures are being studied for providing more sophisticated telecommunication services. New standards for B-ISDN are being developed. Functionalities need to be extracted for controlling multipoint connections and efficient routing. We describe the newly developed service simulator for extracting such functionalities. We propose the call model for multipoint connection services. We also propose the trigger transfer function to call a set-up procedure for multipoint connection service provisioning. The service simulator has installed new functionalities and is able to set up multipoint connections and provide multicast services.
