“…A number of switch algorithms have been developed to provide a fair share of the available bandwidth to each ABR connection. A non-exhaustive list includes [3±8, 12,13,16]. The primary objectives of these algorithms are high utilization and ensuring that each ABR connection receives a fair share of the bandwidth currently available at the switch.…”

The problem of ef®ciency and fairness of Available Bit Rate (ABR) traf®c with Explicit Rate (ER) marking is investigated from a control point of view. It is revealed that due to signi®cant uncertainty on time delays in ABR traf®c and strong interaction among switches, ABR traf®c imposes a great challenge to control strategy development. Focusing on robustness of congestion control and asymptotic fairness, we propose a new control strategy that employs robust control to accommodate delay uncertainty and rate coordination for fairness. Interaction between these two control actions leads to a non-standard multi-objective control problem. Overall stability of the system and convergence to fairness are rigorously analyzed. Conditions are presented under which robust stability and convergence are guaranteed. Simulation tests are then performed to demonstrate that a redesign of feedback controllers may become necessary to satisfy these conditions. q

In this paper, we propose a binary feedback scheme for congestion control in computer networks using a gradient-based mechanism which employs neural network modelling of the system dynamics. The optimal direction for rate adjustment at the source is based on a single bit feedback signal which depends upon the sign of the sensitivity of the system performance index with respect to queue input rate. The paper presents the scheme and the analysis that went into the choice of the various decision mechanisms. Simulation results are presented to show the performance of the gradient based technique as compared to the conventional queue-based approach.
