Abstract
In this paper, we propose an effective fuzzy local fair-Rate generator (FLFG) for resilient packet ring (RPR) to achieve better utilization fairness and convergence time. The FLFG is composed of three components: adaptive fairRate calculator (AFC), fuzzy congestion detector (FCD), and fuzzy fairRate generator (FFG). AFC produces an estimated fairRate in the meantime FCD indicates the congestion degree of station. Finally, FFG adopts the two outputs from AFC and FCD to generate precise local fairRate. Simulation results show that FLFG performs a stable fairness algorithm and improves at least about by 200% in converge time of the fairRate over the aggressive mode (AM) and the distributed bandwidth allocation (DBA) algorithms.
