| Abstract: | In ATM networks, congestion control plays an important role in supporting different qualities of service guarantees for a large variety of traffic categories. In this paper, we put forward an analysis model based on the rate based closed loop mechanism developed by ATM Forum, derive formulae for computing the evolution of an allowed cell rate and queue length, and obtain the maximum and minimum values of the queue length. The simulation results have shown that the formulae derived in this paper are in agreement with the simulation results, and a higher utilization ratio of network resources and a lower buffer requirement can be achieved when the control parameters of the feedback mechanism are selected properly. |
