省域广电IP骨干网的“IPv6+”技术应用与演进探索

Exploration of the Application and Evolution of“IPv6+”Technology in Provincial Broadcasting and Television IP Backbone Networks

面对广电IP数据网固移融合、云网协同和多业务融合承载的发展趋势,本文提出了省域广电IP骨干网建设发展的目标架构和组网设计、路由组织、业务承载等建设内容,借助SRv6原生隧道实现了IPv6单栈部署,通过SRv6 TE policy+FlexE提供业务差异化承载,引入SDN控制器和Telemetry、iFIT技术大幅提升全程全网运维管理和服务保障能力。

Oriented to the development trend of the fixed-mobile convergence,cloud-network collaboration and multi-service convergence,this article proposes the target architecture and network design,routing organization,and service carrying for the construction and development of provincial broadcasting and television IP backbone networks.With the help of SRv6 native tunnels,IPv6 single-stack deployment is realized,and SRv6 TE policy+FlexE is used to provide differentiated carrying of services.SDN controllers,Telemetry,and iFIT technologies are introduced to significantly improve the entire network operation and maintenance management and service guarantee capabilities.
