Service addressing: an approach to the problems of heterogeneity and distribution for VISION O.N.E

It is a self-evident truth that most telecommunications systems are large and complex; they are now increasingly both distributed and heterogeneous. It is now apparent that the software components which comprise them would benefit by being parcelled into discrete units exhibiting well-specified interfaces, offering a service to the rest of the system. Service addressing is a mechanism which is intended to support a system architecture based on service requests and service provision. VISION O.N.E. is a strategy established by GPT and Siemens for the evolution of telecommunications. It comprises all the innovative network elements required for the high-performance networks of the future, building on a set of product platforms. It is an example of a distributed and heterogeneous system. There are two key issues: how the system software is structured and when, and how it operates during run time. The proposed scheme relies on many of the concepts from the domain of object-orientation and the ANSA (advanced network systems architecture) project.
