New rate-based switch algorithm for ABR traffic to achieve max-min fairness with analytical approximation and delay adjustment

In this paper, a new rate-based switch mechanism for ABR traffic in ATM networks, which aims to rapidly achieve max-min fairness allocation, is proposed. Simulation results show that the proposed scheme can out-perform both CAPC [AF94-0983] and ERICA [AF95-0178] in terms of response times and peak queue lengths. An analytical approximation of the performance is also introduced and its accuracy is found to be close to the simulation results. A variant of the proposed scheme is presented for handling the problem of different source-to-bottleneck separations. By using this scheme, the peak queue lengths at the switches can further be reduced without any degradation in throughput
