摘　　要："新基建"带来数据中心发展的新契机,数据中心作为运营商打造云网一体化新型基础设施的重要组成部分,为5G+AI时代的新兴应用提供强大的技术底座。重点分析面向云网融合发展的数据中心网络的新需求,对超大规模组网、超低时延无损网络、业务端到端统一承载等关键技术进行探讨;最后,给出一种大规模云数据中心组网和承载方案,并对其中的关键技术领域进行验证。"New infrastructure" brings new opportunities for the development of data centers. Data center has become an important part of the operator’s cloud-network convergence infrastructure, providing a strong technical foundation for innovative applications in the 5 G + AI era. The new requirements of the data center network in the cloud network convergence background were analyzed. The key technologies in ultra-large-scale networking, ultra-low latency lossless network, and unified service end-to-end bearer were given. Finally, a large-scale cloud data center networking solution were presented, and the key technologies were verified.
