摘要
为提高现阶段广播网络的运营效率,在降低广播网络运维成本的同时提升直播信号的质量和用户体验,提出在电视广播中的直播场景及广播信号处理环节分别部署软件定义网络(Software Defined Network,SDN)和网络功能虚拟化(Network Function Virtualization,NFV)网络架构。利用回传网络采集多场馆的信号,根据实时流量情况动态分配网络资源,同时在应对突发事件或临时增加直播需求时,SDN快速重新配置网络,优化调度直播流量。基于SDN架构,在广播信号处理环节通过NFV技术虚拟化视频编转码和用户权限认证,确保信号处理和分发环节的高效性。
In order to improve the operation efficiency of broadcast Network at the present stage,reduce the operation and maintenance cost of broadcast network and improve the quality of live broadcast signal and user experience,it is proposed to deploy Software Defined Network(SDN)and Network Function Virtualization(NFV)network architectures in live broadcast scenarios and broadcast signal processing.The backfeed network is used to collect signals from multiple venues and dynamically allocate network resources according to real-time traffic conditions.At the same time,SDN quickly reconfigures the network to optimize the scheduling of live streaming traffic in response to emergencies or temporary increase in live streaming demand.Based on SDN architecture,NFV technology is used to virtualize video coding and transcoding and user permission authentication in broadcast signal processing to ensure the high efficiency of signal processing and distribution.
