摘要： 基于中国互联网的发展，以及国家新基建的政策导向，数据中心正在蓬勃发展，数据中心网络也在从10G、40G网络向25G、100G网络过渡，甚至一些头部企业已经在尝试100G、400G网络。同时，随着中美贸易摩擦日渐升级，卡脖子的现象日趋严重，能否基于全自主元器件、网络设备和技术构建云数据中心网络是一个重要课题。云数据中心网络通常包括SDN控制器、交换机、安全设备、网络分流设备、虚拟交换机vSwitch、智能网卡等相关组件，这些组件的硬件和软件都需要是国产自主的，才能摆脱对国外技术的依赖。重点论述自主云数据中心网络的技术特点、相关组件自主化布局的可行性以及自主化的方法和方案选择。

Research on network technology exploration and solutions for independent cloud data centers of large domestic enterprises

Abstract： Based on the development of China′s Internet and the policy orientation of the country′s new infrastructure, data centers are booming, and data center networks are also transitioning from 10G and 40G networks to 25G and 100G networks. Even some leading companies are already experimenting with 100G and 400G networks. At the same time, with the escalating trade friction between China and the United States, the phenomenon of neck stuck is becoming more and more serious. Whether it is possible to build a cloud data center network based on fully autonomous chips and technology is an important issue. Cloud data center networks usually include SDN controllers, switches, security devices, network offloading devices, virtual switches vSwitch, smart network cards and other related components. The hardware and software of these components need to be domestically independent to get rid of the dependence on foreign technology. This article focuses on the technical characteristics of the autonomous data center, the feasibility of the autonomous layout of related components, and the choice of autonomous methods and solutions.
