摘要
随着融媒体时代的到来,视频、音频、图文等多种媒体形态呈现融合趋势,对广电网络提出了全新要求。多业务混合承载对广电网络的架构设计、资源调度以及质量保障能力提出了全新的考验。对此,分析融媒体环境对广电网络的影响,阐述广电网络实施多业务混合承载的必要性,提出一种面向多业务混合承载的创新性广电网络架构设计方案,重点探讨接入网络承载和城域网络承载两部分架构,并基于混合承载的整体设计,提出基于网络功能虚拟化(Network Functions Virtualization,NFV)的业务隔离优化策略。
With the advent of the era of integrated media,video,audio,graphic and other media forms show a trend of integration,which puts forward new requirements for radio and television networks.The multi-service hybrid carrier puts forward a new test to the architecture design,resource scheduling and quality assurance ability of broadcasting network.In this regard,this paper analyzes the impact of financial media environment on radio and television network,expounds the necessity of implementing multi-service hybrid bearer in radio and television network,and proposes an innovative design scheme of radio and television network architecture for multi-service hybrid bearer,focusing on the two architectures of access network bearer and metropolitan network bearer,and based on the overall design of hybrid bearer.An optimization strategy for service isolation based on Network Functions Virtualization(NFV)was proposed.
