Abstract

The end-to-end QoS of streaming video on a joint metro and access network is investigated. SUCCESS DWA PON is a highly scalable broadband access network, which can bridge current TDM PON and future WDM PON smoothly and cost-effectively. The IEEE 802.17 Resilient Packet Ring is an emerging MAN standard that designs for efficient packet-based traffic transmission over rings. A realistic video service model is constructed on this joint network, where one of the RPR nodes is dedicated to feed VBR video streams to the end-users in the presence of self- similar Internet traffic. Two improvements are proposed to improve the observed shortcomings in the video streaming performance. To improve the QoS of the streaming video, an additional transit queue is added in the RPR mode to reduce end-to-end delay. In addition, the RPR fairness algorithm is modified to improve the class-C traffic throughput. Simulation results show combined video QoS and total throughput enhancement with the proposed modifications.

联合成功DWA PON和改进型RPR网络中视频流服务的端到端QoS研究

研究了城域网和接入网的视频流端到端QoS问题。成功DWA PON是一种高度可扩展的宽带接入网，可以平滑、经济地连接当前TDM PON和未来WDM PON。IEEE 802.17弹性分组环是一种新兴的城域网标准，旨在通过环实现高效的分组流量传输。在该联合网络上构建了一个现实的视频服务模型，其中一个RPR节点专门为终端用户提供自相似Internet流量下的VBR视频流。本文提出了两种改进方法来改善视频流性能的不足。为了提高视频流的QoS，在RPR模式中增加了一个额外的传输队列，以减少端到端延迟。另外，对RPR公平性算法进行了改进，提高了c类流量的吞吐量。仿真结果表明，改进后的视频服务质量和总吞吐量得到了综合提高。
