摘　　要：目前已有的QoS流量控制方法大多存在对网络资源的利用率低、可靠性差、粒度粗、实现困难、可扩展性差等问题。如何利用有限的网络资源进行有效的流量控制,以保障业务的服务质量(quality of service,QoS)已成为一个非常迫切的问题。为解决此类问题,借鉴软件定义网络(software defined network,SDN)提出的控制层与数据层分离新思想,提出了一种基于OpenFlow技术的QoS流量控制方法,利用自适应多约束QoS路由技术提高了QoS控制的灵活性与可靠性,实现了对网络资源的高效利用和业务流控制的细粒度。实验结果验证了其有效性。The existing QoS traffic control methods still have many issues such as utilization of network resource,reliability,scalability,control granularity,complexity of implementation. It is urgent to guarantee QoS of applications with effective flow control constrained by network resources. This paper proposed an Open Flow based QoS traffic control method,referring to the new idea of separating controlling layer and data layer provided by SDN. It took advantage of adaptive multi-constrained QoS routing technology,which improved flexibility and reliability for Qo S control,to achieve effective usage of network resources and fine-grained of flow control. The experimental results validate its effectiveness.
