摘    要:
IEEE802.17弹性分组环是宽带城域网的新型技术。凭着本地公平算法、空间重利用、带宽统计复用、正常状态双环均传输业务等特点从而和传统环网相比,弹性分组环在带宽利用方面具有较大的优势。公平算法对弹性分组环发挥其带宽利用优势具有极其重要的作用,而目前的基于节点公平算法不能完全发挥弹性分组环的优势。文章在更能发挥弹性分组环带宽利用优势的基于流的公平策略的基础上,建立相应的算法方案,并进行计算机仿真验证。实验结果验证了理论分析。

关 键 词:弹性分组环  公平算法  基于流

Abstract:
Resilient Packet Ring (RPR) is a metropolitan area network technology for data transfer based on ring configuration and is standardized as IEEE 802.17. In the fields of local fairness, spatial reuse and bandwidth utilizationRPRhas acomparativelyhigh superiority. And fairness algorithm is very important for RPR. llowever, the current fairness protocol and its adaptions based on nodes eou]dnot give full play to the superiority of RPR. Thus the corresponding fairness solution based on flows is proposed, which could give full play to the superiority of RPR advantages of RPR. The simulation results have proved the theoretic analysis.
Keywords:Resilient Packet Ring (RPR)  fairness algorithm  flow-based
