MODELING AND PERFORMANCE ASSESSMENT OF LARGE ATM SWITCHING-NETWORKS ON LOOSELY-COUPLED PARALLEL PROCESSORS

A parallel simulation tool has been developed with the aim of evaluati ng 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 revea led with respect to the model being built. The performance of the para llel tool is examined, based on a scalable ATM switching network, by m eans of a loosely-coupled parallel computer system. A combination of g eneral purpose and problem specific algorithms results in a high compu tational efficiency, portability and scalability.
