广电5G承载网规划研究

The Planning Strategy of 5G Bearer Network for China Broadcasting

中国广电运营多年,在光纤到户已完成的背景下,具备丰富的固网资源,但网络架构和带宽仍无法满足未来5G的业务需求。基于广电开始着手5G规划的背景,阐述广电承载网的网络架构重组方案、OTN和IPRAN实施规划、光缆及管道规划,将广电树型网络架构逐步过渡至环形OTN组网,以满足未来5G的承载需求,为广电5G承载网规划和建设提供理论和实践指导。

China Broadcasting has been operating for many years.Under the background of completion of optical fiber to home,China Broadcasting has abundant fixed network resources,but the network architecture and bandwidth still cannot meet the business needs of 5G in the future.Under the background of this article is based on China Broadcasting started to 5G planning,expounds the network architecture of China Broadcasting and bearer network restructuring,its OTN and IPRAN implementation planning,cable and pipe planning.It gradually transitioned the tree network architecture to the circular OTN networking to meet the carrying demand of 5G in the future,and provided theoretical and practical guidance for the planning and construction of China Broadcasting 5G bearer network.
