Adaptive Deadbeat Congestion Control Algorithm for ABR Traffic in ATM Networks

Abstract

This paper presents an adaptive deadbeat control algorithm for the ABR traffic congestion control in ATM networks. We consider a control-based mathematical model and apply the tracking feedback deadbeat control design, online plant parameter identification and controller parameter modification algorithm to the problem. The practical control issues of output buffer saturation and initial conditions are considered in the control scheme. Simulations are implemented to verify the proposed control design. It is shown that the control algorithm satisfies the requirements of fairness to users, network efficiency, unknown time-varying delays and queue control. Moreover, the control algorithm is simple and a fast guaranteed convergence is obtained.
