Imporving RPR fairness convergence
Chuan-Gang Liu, Jung-Shian Li · 2005
IEEE 802.17 RPR is a MAN candidate due to its ability to achieve fairness and fast restoration. However, the proposed fairness scheme may lead to slow convergence and permanent oscillation. This letter proposes a novel fast-convergent scheme to provide fairness using estimated number of unbounded flows in each link. After detailed evaluations and simulations, the proposed scheme is proven to allocate bandwidth fairly among flows fast-convergently and achieve high utilization at the same time.
