One of the key techniques of Resilient Packet Ring (RPR) is ring distributed fairness algorithm.While some deficiencies exist in the fairness algorithm recommended by current draft standard of RPR (IEEE802.17 draft)

such as long convergence time of fairness algorithm in high-speed RPR network and serious throughput oscillation caused by unbalanced traffic flow.This paper proposes a new fairness algorithm to solve these problems.The simulation results show that this algorithm not only solves the unbalanced traffic problem but also controls fairly the bandwidth allocation among stations.
