On the dimensioning of the leaky bucket policing mechanism for multiplexer congestion avoidance

In this paper a model for an ATM multiplexer fed with bursty sources, controlled by the leaky bucket traffic controller is developed. Based on a suitable application of this model, a dimensioning procedure for the leaky bucket is proposed and its effectiveness analysed, considering the steady state cell loss probability as the performance measure for the multiplexer. Some numerical results are presented as an example, showing that the policer can play an important role in maintaining the network quality of service in case of unfairness in the source behaviour.
