The fairness algorithm of the Resilient Packet Ring IEEE 802.17 standard suffers from throughput degradation under an unbalanced overload. This letter proposes an enhanced fairness algorithm using a valuable piece of information, represented by the transit buffer length, about congestion alleviation on a congested node, under which the throughput degradation can be completely improved.
