As the core platform for the aggregation, sharing, and exchange of government data, the autonomy, controllability, and stability of its time synchronization system are directly linked to the efficiency and compliance of cross-departmental data exchange, electronic certificate and license approvals, and the handling of government services. Beijing Zhongxinchuang Technology Co., Ltd.'s The DNTS-9HG domestically developed, indigenous‑innovation time server, with its comprehensive domestic‑compatibility support and robust time‑synchronization performance, has been successfully deployed in multiple provincial government‑cloud projects, laying a solid temporal foundation for digital government initiatives. This paper examines the device’s end‑to‑end deployment strategy across all scenarios in provincial government clouds, focusing on three key dimensions: deployment requirements, implementation procedures, and operational‑maintenance assurance.

• Core Requirements for Time Synchronization in Provincial Government Clouds The provincial government cloud spans dozens of prefecture-level cities and hundreds of districts and counties across the province, supporting core functions such as government services, data governance, and emergency command. It places four key requirements on the time‑synchronization system: 1. **Autonomy and Controllability**: The system must be built on domestically produced hardware and operating systems to eliminate reliance on external technologies and comply with government‑grade cybersecurity requirements. 2. **High Concurrency Support**: It must simultaneously provide time synchronization for tens of thousands of government servers, terminal devices, and business systems, with processing capacity tailored to handle the demands of a massive number of nodes. 3. **24/7 Stability**: Given the nonstop nature of government operations, the time‑synchronization system must operate without interruption to prevent data‑exchange failures caused by time discrepancies. 4. **Visualized Operations and Maintenance**: An accompanying intelligent management tool is required to enable centralized control of all time‑synchronization devices across the province, thereby reducing cross‑regional O&M costs.
• DNTS-9HG Deployment Scheme for Government Clouds In response to the requirements of provincial-level government clouds, Zhongxin Chuang has customized a “1 primary + multiple backups” cluster deployment solution, with the following core configuration: 1. **Core Hardware Selection**: The primary node is equipped with the DNTS‑9HG server powered by Hygon’s 5000‑series CPU, paired with 32 GB of memory and a 1 TB enterprise‑grade SSD, meeting high‑concurrency processing demands. The backup nodes utilize Phytium’s 2000+ series CPUs, forming heterogeneous redundancy with the primary node to further enhance system reliability. All components are sourced from domestic manufacturers and have passed ISO 9001 quality certification as well as government‑specific information technology adaptation assessments, ensuring hardware‑level autonomy and controllability. 2. **Time Source Configuration**: A dual‑redundancy approach is adopted—“Beidou single‑system plus local timekeeping.” The primary time source is the Beidou satellite navigation system, while the backup is an onboard rubidium atomic clock; automatic switchover occurs when satellite signals are disrupted, guaranteeing uninterrupted time synchronization. 3. **Network Architecture Deployment**: The DNTS‑9HG is deployed adjacent to the government cloud’s core switch, connected via Gigabit or 10‑Gigabit Ethernet ports to the internal cloud network, with one external network interface reserved for signal calibration. VLAN segmentation is employed to isolate time‑synchronization traffic from business traffic, preventing network congestion that could compromise timing accuracy. 4. **Software Adaptation**: The system runs Zhongxin Chuang’s intelligent, full‑network unified time‑monitoring software, version 4.0, which seamlessly integrates with existing government cloud operations platforms such as Zabbix and cloud management systems, enabling centralized monitoring and management.
• Deploy and implement key processes 1. **Preliminary Site Survey and Customized Solution Design**: The technical team visited the government cloud data center to conduct an on-site assessment of the server room environment, network topology, and existing equipment. Based on the scale of the business, they adjusted the number and configuration of devices to develop a tailored deployment plan. 2. **Hardware Installation and Commissioning**: Using standard 19-inch rack‑mount units, the team installed the equipment, connected power supplies, and deployed antennas. They then performed basic network configuration and timing parameter tuning, verifying both BeiDou signal reception and timekeeping performance. 3. **Software Integration and Cluster Deployment**: Intelligent monitoring software was deployed, with heartbeat detection and data synchronization configured between primary and backup nodes to enable automatic failover. The system was also integrated with the government cloud’s operations platform, exposing API interfaces to facilitate seamless data exchange. 4. **Stress Testing and Stability Validation**: To simulate high‑concurrency scenarios typical of government cloud environments, stress testing tools were used to evaluate the equipment’s concurrent processing capacity—supporting over 500,000 simultaneous client requests—with timing deviations kept within nanoseconds, meeting the stringent requirements of the government cloud. 5. **Staff Training and Project Handover**: Operational training was provided to the government cloud’s maintenance team, covering device configuration, monitoring, troubleshooting, and other critical tasks, ensuring a complete handover of the entire solution.
• Deployment Outcomes and Industry Value In a certain provincial-level government cloud project, Following the deployment of the DNTS‑9HG cluster, unified time synchronization has been achieved across all 128 government departments in the province, covering 32,000 terminal devices, with time deviations consistently maintained within ±0.5 μs. This has completely resolved issues of temporal consistency in cross‑departmental data exchange. The electronic certificate‑issuance approval process on the government service platform has seen a 30% efficiency improvement, and the emergency command system now achieves 100% accuracy in command‑synchronization. At the same time, the solution meets the requirements for independent and controllable development of government information infrastructure, making it a benchmark implementation of a provincial‑level government cloud time‑synchronization system.
