High performance simulation for ATM network development

Abstract

Techniques for measuring and modeling ATM traffic are reviewed. The requirements for cell level ATM network modeling and simulation are then outlined followed by a description of an ATM traffic and network (ATM-TN) simulator. This ATM-TN simulator is built upon parallel simulation mechanisms to achieve the high performance needed to execute the huge number of cell events required for a realistic network scenario. Results for several simulation experiments are reported using this high performance simulation including scenarios for the Wnet and OPERA networks. Finally, a preliminary evaluation of the application of high performance simulation to the design and analysis of ATM network performance is provided.
