In this paper, a novel Software-Defined Networking (SDN) architecture is proposed for high-end Ultra High Definition (UHD) media applications. UHD media applications require huge amounts of bandwidth that can only be met with high-capacity optical networks. In addition, there are requirements for control frameworks capable of delivering effective application performance with efficient network utilization. A novel SDN-based Controller that tightly integrates application-awareness with network control and management is proposed for such applications. An OpenFlow-enabled test-bed demonstrator is reported with performance evaluations of advanced online and offline media- and network-aware schedulers.
本文针对高端超高清(UHD)媒体应用提出了一种新颖的软件定义网络(SDN)架构。UHD媒体应用需要大量带宽,只有高容量光网络才能满足这一需求。此外,还需要能够通过高效的网络利用来提供有效应用性能的控制框架。针对此类应用,提出了一种基于SDN的新型控制器,该控制器将应用感知与网络控制和管理紧密集成。报告了一个启用OpenFlow的试验台演示器,并对先进的在线和离线媒体与网络感知调度器进行了性能评估。
