According to the official WeChat public number of the National Development and Reform Commission, recently, the National Development and Reform Commission, the Central Network Information Office, the Ministry of Industry and Information Technology, and the National Energy Administration jointly issued the “Implementation Plan for the Arithmetic Hub of the National Integrated Big Data Center Collaborative Innovation System” (Development and Reform High Technology  No. 709, hereinafter referred to as the “Plan”), which clearly proposes to layout the national hub nodes of the national arithmetic network and launch the implementation of The Plan clearly proposes to lay out the national hub nodes of the national computing network, start the implementation of the “East Digital West Computing” project, and build the national computing network system. The Program layout in Beijing, Tianjin and Hebei, Yangtze River Delta, Guangdong, Hong Kong and Macao Bay Area, Chengdu and Chongqing, as well as Guizhou, Inner Mongolia, Gansu, Ningxia construction of the national arithmetic network national hub nodes (hereinafter referred to as “national hub nodes”), focusing on promoting the layout of data centers, network, electricity, energy consumption, arithmetic, data and other aspects of integrated planning, the national The National Hub Node is the backbone connection point of China’s arithmetic network. Through the national hub node, the layout of data center construction is planned in a coordinated manner, and large-scale data centers are guided to gather moderately and form data center clusters. Between the clusters and the clusters, a high-speed data center direct connection network is established to implement the “East Data and West Computing” project to support large-scale computing power scheduling and build a new computing power network pattern oriented to data flow.
