摘　　要：Open Flow是软件定义网络(Software Definded Network,SDN)的产物,是一种新型的网络结构,且发展十分迅速。但Open Flow网络的Qo S功能仍待优化,针对于Open Flow网络中流媒体传输Qo S的不足,在现有网络Qo S模式基础上提出了Open Qo S,它应用于Open Flow网络的控制器上,采用动态路由的方式,使得流媒体在网络端到端传输时,能够根据网络状况,动态改变路由路径,进而提高网络Qo S。最后,通过一个小的拓扑网络对本研究进行了试验验证。OpenFlow is SDN（Software Definded Network） product, is a new network architeeture, and developed rapidly. But the QoS fuetion of OpenFlow Network also need to be optimized. For the lack of streaming media transmission in OpenFlow network, it proposeS OpenQnS on the existing network model. It is applied on the OpenFlow network controller,using dynamic routing approach, making streaming media transmission end to end in network, could according to network conditions, changing routing paths, so can a- chieving the purpose of the network QoS. Finally, the research is verfided through the design of a small topology experimental.
