Abstract

This paper discusses modeling and simulation of ATMTraffic Management. It presents a survey on therequirements needed for such task considering previouswork in the area. The survey encloses the followingtopics: the modeling approach; the requirements fortrustworthy performance and QoS analysis; and thechoice of the simulation environment where the modelswill be implemented. The paper also presents a new ATMnetwork model implemented in a communication systemssimulation environment called SimNT 2.0. The networkmodel covers SVC routing and management, ATM trafficmanagement functions, packet and celltransport/processing and clients behavior. The TMfunctions taken into account include per-VC queuing,weighted fair-share scheduling, traffic shaping, effectivebandwidth connection admission control, selective celldiscarding, leaky-bucket traffic policing and trafficcontract configuration and negotiation. Numerical resultsbriefly demonstrate the network model.
