Development life cycle of computer networks: the executable model approach

An approach is proposed for extending the use of design models to the implementation and operational phases of the network development life cycle. A conceptual approach is offered for using executable models in the day-to-day operation of computer networks. Several strategies are given for integrating models into different development tasks. It is shown why these strategies are feasible. Characteristics of executable models that differ from those of traditional models are identified along with new technologies that reduce the cost of implementing and using executable models
