摘要

尽力而为的IP网络难以满足日益提高的服务质量需求，亟需研发一种兼容现有IP软硬件资源的QoS控制机制。为此，提出了一种基于软件定义网络的区分服务优先权的流控机制PriQoS。当网络资源紧缺时，使用基于业务流综合优先权的多队列带宽分配算法来满足高优先权流的带宽需求；PriQoS部署在网络边缘，无需修改端系统应用程序和核心网路由器，具有易于部署、与IP应用和设备兼容的优点。实验结果表明PriQoS机制能够优先保证高优先权业务的服务质量。

Abstract

It was difficult to meet the increasing demand of quality of service (QoS) for the best-effort IP network

so it was urgent to develop a kind of QoS control mechanism that was compatible with the existing IP software and hardware resources.Therefore

a priority-differentiated control mechanism based on the software defined networking called PriQoS was proposed.When the network resource was scarce

a multi-queue bandwidth allocation algorithm based on the inte-grated priority of service flow was used to meet the bandwidth requirement with high priority flows.PriQoS was deployed on the network edge

which was no need to modify applications in the end systems and routers in the core network.The mechanism has advantages such as easy to deploy and being compatible with the IP applications and devices.Experimental results show that the PriQoS mechanism can guarantee the QoS of higher priority services.
