Core Viewpoint - The Ministry of Industry and Information Technology (MIIT) has launched a special action plan to develop a metropolitan "millisecond computing" network, aiming for a coverage rate of at least 70% by 2027, enhancing the efficiency and accessibility of computing resources across the country [1][3]. Group 1: Overall Strategy and Goals - The initiative focuses on developing a high-speed, low-latency metropolitan network that provides millisecond-level computing resource accessibility, with specific targets for interconnection and access times [4]. - By 2027, the plan aims to achieve less than 1 millisecond latency for interconnections between medium and large computing centers and less than 10 milliseconds for applications to computing centers [4]. Group 2: Action Content - The plan includes three main actions: 1. Promoting "millisecond interconnection" between computing centers, with a target of 50% deployment of 400Gbps connections by 2027 [5]. 2. Enhancing "millisecond access" to computing resources, aiming for a coverage rate of at least 70% for 1 millisecond latency circles by 2027 [5]. 3. Improving "millisecond accessibility" for applications, targeting a network latency of less than 10 milliseconds from application terminals to computing servers by 2027 [6]. Group 3: Implementation Requirements - Local communication management departments are tasked with selecting cities with high computing resource density and good network infrastructure to implement the action plan, with a maximum of three cities per province [7]. - A mid-term evaluation will be conducted one year after the action's initiation, requiring local departments to report network monitoring data to the national platform [7]. - At the end of the action period, a summary of the implementation will be required, with results evaluated and published by the MIIT [8].
