摘　　要：针对SDN对多业务服务质量QoS管控的缺乏,在综合考虑网络发展和运营商对QoS需求的基础上,设计了一套适用于OpenFlow网络的QoS管理机制,并对管理系统的架构、管理层面的交互和通过配置静态流规则中Action动作实现DiffServ模型流分类、标记和入队等流量控制机制的过程进行了详细阐述,最后通过搭建小型网络拓扑对其进行实验验证,结果证明,该系统对分类业务QoS管控的可行性和有效性。In view of the lack of quality of services QoS in the SDN, considering the network development and the demand of QoS operator, a QoS man-agement mechanism based on OpenFIow network is designed in this paper. And then, the architecture of the management system and the interaction of management level are described. The implement of classification, marking and enquired in the flow control mechanism based on DiflServ model through configuring static flow rules in Action Entry are analyzed. Meanwhile, the experimental verification is also given based on constructing small network to-pology. The results prove that the system has feasibility and effectively in the OpenFlow network.
