A Fast Switch Algorithm for ABR Traffic to Achieve Max-Min Fairness

In this paper, a new rate-based switch mechanism is proposed for flow control of ABR traffic. By making use of the most upto-date information from both the upstream and the downstream paths, the current bottleneck of the VC can quickly be found. The bandwidth allocation for different VCs can then be adjusted by using this new bottleneck information to achieve max-min fairness allocation [1]. We compare the proposed scheme to CAPC [2] and ERICA [3]. Simulation results showed that the transient response times of the sources are significantly reduced in the proposed scheme. Furthermore, the peak queue lengths of the switches are generally smaller.
