面向OpenFlow的内容分发网络视频流传输策略
OpenFlow oriented content delivery network video stream transmission strategy
摘要
Abstract
We propose a new content delivery network (CDN) architecture based on software defined networking(SDN).It improves the interfaces of the OpenFlow controller.With the help of scalable video coding(SVC) on the base layer,the video can be transmitted in a lossless-QoS way,while the enhancement layers routed in a best effort way.Through multiple scenarios simulation experiments,the architecture proposed in the paper can effectively improve the video's overall PSNR and good video transmission service quality under network congestion.关键词
