Abstract

We propose a dynamic regulation scheme which makes use of scheduler feedback information to reduce the mean delay of multimedia traffic. Traditional methods do not consider the state of a scheduler and a cell will wait in the regulator even when the queue of the scheduler is empty, resulting in a long delay of the involved cells. We use a dynamic scheme whose regulation function is modulated by both the tagged stream's characteristics and the state of the scheduler. As a result, the mean delay of the traffic can be controlled. In particular, the mean delay can be greatly reduced in the case when the scheduler's queue is empty. Simulation results have shown that the mean delay of our dynamic scheme is less than that of other methods.
