摘要
弹性分组环(RPR,ResilientPacketRing)作为下一代高速城域网的核心技术,具有高的带宽利用率、空间再利用和公平性等优良的特性。但要动态地获得这些特性,必须设计合理的带宽分配算法。文章指出了目前所采用的公平算法中存在的一些问题,探讨了一种更新的带宽分配算法:分布式虚拟时间调度(DVSR,DistributedVirtual-timeSchedulinginRings)算法。
The resilient packet ring （RPR） is a new technology for high-speed backbone metropolitan area networkso A key performance objective of RPR is to simultaneously achieve high utilization, spatial reuse, and fairnesso The core technical challenge for RPR is the design of a bandwidth allocation algorithm that dynamically achieves these three propertieso In this paper, we introduce some problems in current fairness algorithm,and discuss a new dynamic bandwidth allocation algorithm called DVSR（Distributed Virtual-time Scheduling in Rings）.
