Object-oriented modeling, simulation and implementation of a network management system

Development of a network management system for B-ISDN access products proceeded through a modelling phase at a high level of abstraction, followed by implementation in an expert-system shell dedicated to network management. The expert-system shell provides the opportunity to exercise the system in simulation mode. The object-oriented paradigm is used for modelling, implementation and simulation. Some of the modelling techniques employed are highlighted and followed by an overview of the environment which simulates and implements the system. Finally, some strategies for transforming a model at a high level of abstraction into an implementation are discussed
