Abstract

Congestion control plays an important role in the effective and stable operation of ATM networks. The emerging B-ISDN is expected to adopt ATM (asynchronous transfer mode) as the transport network. This new network must support several classes of service with varying delay and loss requirements, such as voice, audio, data, and high quality video. It must also operate with link speeds in the hundreds of megabits per second and be scalable up to potential link speeds on the order of gigabits per second. The requirements to support multiple services and high speed pose problems not previously faced in traditional packet switched networks. Reactive methods of control become less effective due to the large propagation delay-bandwidth product. This paper first gives a historical overview of congestion control algorithms developed in the ATM Forum, showing how the current ATM Forum standard regarding the traffic management control methods is exploited, by these algorithms. Then, analytical approach is used to quantitatively evaluate their performance and show the effectiveness of that approach. In presenting the numerical examples, we emphasize that appropriate control parameter settings are essential for proper traffic management in an ATM network environment.
