Analysis of a broad band packet network with rate based network access control

The author develops analytic models to analyze the performance of a broadband packet networks using a new rate-based network access control known as the distributed source control (DSC). The waiting time distribution at each queue is determined, as well as the size of the end-to-end window necessary to achieve a given throughput. The optimum rate or throughput in the sense of minimizing the network delay over throughput is found, and the effects of different burst sizes, cell arrival rate, link utilization, and link capacity on the network performance are studied. It is shown that, with proper choice of the DSC control parameters, one can achieve a good grade of service in terms of cell loss with a small pool of buffers even at high utilization
