针对当前互联网流媒体传输的时延敏感性问题,提出一种基于Openflow的Flash P2P流媒体传输框架以及tagtable流媒体包分发路由转发技术.Openflow基于流表实现了多级流水转发处理,然而Openflow不支持对流媒体应用层网络中资源和路由等的描述,因此很难支持以视频内容为中心的流媒体网络.为扩展SDN能力,提出了一种基于Openflow的流媒体传输架构.该架构针对Flash P2P流媒体标签tagtable路由转发和Openflow灵活可编程的特性,在网络带宽受限和链路拥塞的复杂网络环境下,通过构建由支持网络层的Openflow的流表路由转发进而适用于应用层具体媒体应用流表路由转发的高效传输.

For Delay sensitive issues of the current Internet streaming media transmission,a Flash P2P streaming media framework and a routing distribution technology of tagtable streaming package based on Openflow is proposed. Openflow has realized the streaming for-warding processing based on streaming table,is difficult to support streaming media network with video content as core,which cannot support the processing network resources and routing resources of the streaming media in Openflow application layer. To expand the ca-pacity of SDN,propose a streaming media transmission framework based on Openflow. The architecture is designed for Flash P2P stream-ing media forwarding and routing by using tagtable and the flexible programmable features of Openflow. Build an efficient transmission which is used to the specific application in a complex network environment and limited network bandwidth in application layer which is different from the flowtable is only supported in network layer.
