Abstract

This paper presents a simulation study into the problem of conveying Internet protocol (IP) packets over an asynchronous transfer mode (ATM) network in cases where quality of service (QoS) is an important consideration. The main focus of the work is on mapping IP packet flows onto ATM cell streams, particularly for the purpose of maintaining the QoS requirements of continuous media (audio and video) traffic. Simulation models of two different flow-mapping scenarios are described, and results of an evaluation of the flow-mapping process are presented. These results are also used to validate an analytical solution to the problem, which has been developed in a separate but related piece of work.
