Modeling and performance analysis of ATM LANs

Asynchronous Transfer Mode (ATM} is a method of data transmission using small fixed-length cells. This thesis presents a model of an ATM LAN which provides a realistic representation of data transmission over the system by explicitly modeling both the ATM network and the applications running over that network. Coloured timed Petri nets are used to create a compact model that is capable of representing a variety of different protocols at a high level of detail. The model is designed to allow easy reconfiguration or addition of detail at different levels of the system. Simulation is used to evaluate the performance of the model, and results are compared to actual data gathered from the Memorial University campus network

Simulation Comparison of Broadband Networking Technologies

This paper describes a simulation study comparing delay and throughput performance of several access/backbone combinations of Frame Relay, Asynchronous Transfer Mode (ATM), and IEEE 802.6 broadband networking technologies. The comparisons are made using similar Metropolitan Area Network (MAN) configurations supporting integrated traffic from voice, video, data and image sources. Results include complete distributions for network and end-end delays. These delay distributions are obtained for different traffic loads and different numbers of network trunks in a connection. All of the configurations are capable of providing adequate delay performance at moderate network loads for real-time (voice and video) traffic, but significant differences are seen in data and image delay performance
