| Abstract: | The single bottleneck node model of asynchronous transfer mode (ATM) networks is considered and the queue length in buffer is regarded as a scale to evaluate the quality of service of networks. To avoid congestion, an algorithm based on interior model control is proposed and the analysis of stability is given. The algorithm guarantees that there is no steady-state error between the queue length and its desired value and enables the network system to distribute the available bandwidth fairly, thus increasing link utilization, decreasing the cell loss rate and guarantessing the quality of service. The simulation proves the validity of this scheme. |
