Performance of an ATM network with multimedia traffic-a simulation study

The asynchronous transfer mode (ATM) allows real-time (RT) and non-real-time (non-RT) traffic to share the same network. These traffic types have different characteristics and requirements. This paper investigates different network access policies for an ATM network with heterogeneous traffic. The performance of a single queue model is examined and compared to the performance of a dual queue model, with different priorities of service. The goal is to provide flexible bandwidth allocation to benefit RT traffic without reducing the level of service to non-RT traffic significantly
