Abstract :
The available bit rate (ABR) service has been proposed by the ATM Forum in 1994 and also adopted by the ITU shortly afterwards. This paper presents the performance of a rate-based ABR in the presence of bursty data applications. Based on measurements reported in the literature, we have developed a simulation tool to evaluate the performance of the rate-based ABR mechanism. The simulation model includes a complete protocol stack allowing us to study the interaction of the traffic control mechanisms implemented by protocols at different layers, i.e., TCP and ABR. Under realistic traffic models, it is shown that the rate-based ABR mechanism provides a high link utilization, minimum buffering requirements and cell transfer delays
