Designing Advanced Services for Distributed Intelligent Broadband Networks

The Intelligent Broadband Network (IBN) enables efficient provision of advanced multimedia services to users, exploiting the benefits of the ATM technology and hiding the limitations of current signalling systems to IBN service designers. The availability of technologies like DOT (Distributed Object Technology) and MAT (Mobile Agent Technology) opens new horizons towards the Distributed Intelligent Networks (DIN). Among the main issues that need to be addressed, in the area of the DIN, are the deployment, provision and control of advanced services. The potentials originating from the utilisation of DOT and MAT along with the employment of concepts and ideas coming from the object oriented design patterns community provide the basis for enhancements in the service design and creation process. This paper introduces a set of implementation principles for the service creation, deployment and management and shows their implications on the overall system architecture. We argue that with the proposed principles, reusability for easy and rapid deployment of services, extensibility towards new and updated services and flexibility on service design can be achieved.
