Modelling and performance assessment of large ATM switching networks on loosely-coupled parallel processors

Abstract

A parallel simulation tool has been developed with the aim of evaluating the performance of a class of ATM switching systems. In this paper, the class of ATM switching networks of interest and the corresponding modelling are addressed. An appropriate decomposition scheme is revealed with respect to the model being built. The performance of the parallel tool is examined, based on a scalable ATM switching network, by means of a loosely-coupled parallel computer system. A combination of general purpose and problem specific algorithms results in a high computational efficiency, portability and scalability.
