【摘要】 弹性分组环 (RPR)中最关键的技术之一是环路分布式公平算法 .IEEE80 2 .17工作组制定的RPR草案中关于公平算法存在一些待完善的问题 ,比如在高速的网络中存在较长的收敛时间 ,同时对于非平衡流带来的永久性震荡现象也无法消除 .本文针对上述这些问题提出了一种新的公平算法 .仿真结果表明算法不仅能够消除非平衡流问题 ,而且能够公平地控制站点之间带宽的分配 .更多还原

【Abstract】 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.更多还原
