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SVC(scalable video coding,可分级视频编码)流媒体时延自适应分级传输方法,该方法有效结合SVC流媒体可分级和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,通过构建基础层和增强层2个独立路由,实现了动态网络下SVC流媒体分级自适应高效传输。仿真结果表明,该方法在提升SVC流媒体传输效率和质量,改善用户体验方面有重要作用。
For the current internet streaming media transmission delay sensitivity issues
a delay adaptive method for SVC (scalable video coding) streaming media transmission based on OpenFlow was proposed. This method combines SVC streaming scalable and flexible programmable features of OpenFlow effectively
and implements SVC streaming hierarchical adaptive transmission in a dynamic network
by building the base layer and the enhancement layer separate routes under complex network environment with limited network bandwidth and link congestion. Simulation results show that this method has an important role in improving efficiency and quality of the SVC streaming
so it can improve the user experience effectively.
