In this paper classical control theory is applied to design a rate-based control law for throttling ABR input rates in high speed ATM networks. At first, a mathematical model for the interaction of ABR-flows with network-queues is developed. Then the control law is designed by following classical Smith's (1959) principle. To implement the resulting EPRCA scheme, a switch architecture consisting of a single FIFO queue per each output link is required. Moreover, network switches do not have to perform any measurement of ABR available bandwidth. Finally, it is theoretically shown that the proposed control algorithm is stable and guarantees full utilization of network links along with max-min fairness in bandwidth allocation.
