摘要

弹性分组环（RPR）技术的一个重要目标是在环网上同时实现带宽的高利用率、空间重用和节点接入的公平性。文章阐述了公平性的概念

讨论了分组公平性的不同模型

研究了空间重用协议（SRP

Spatial Reuse Protocol）和分布式虚拟时间分组（DVSR

D istributed V irtual-Tim e Schedu ling in R ings）的算法思想

指出了DVSR在环网中的优越性。最后

给出了环网公平策略的基本要求和评价准则。

Abstract

An important objective of RPR technology is to simultaneously achieve high utilization

spatial reuse

and fairness. This paper expounded the concept of fairness. discussed different models for analysis of fairness

studied the algorithm of SRP （Spatial Reuse Protocol） and DVSR （Distributed Virtual Time Scheduling）

pointed out the superiorities of DVSR in the RPR. Lastly

the paper presented the basic requirements and the criterion of evaluation for RPR fairness strategy.
