A parallel processing simulator for a network system using multimicroprocessors

A parallel processing simulator, NEWTS, has been developed for network systems. This simulator consists of a number of microprocessors, which are interconnected with one another by hierarchical common buses and which excute simulation programs concurrently. This simulator is far cheaper than a general-purpose large computer and enables carrying out efficient and high speed network simulations. This simulator has been applied to a telephone network model, and it's usefulness confirmed. This paper describes an outline of the NEWTS hardware and software.
