IV. Purchased Products

NTP Server (Model: DNTS-9 ), the configuration includes GNSS Multi-satellite receiver (supports GPS / Beidou / GLONASS/Galileo Multi-system support, dual-antenna redundancy design, rubidium atomic clock (optional temperature-compensated crystal oscillator), 1+1 Hot-swappable dual power supplies, 10 RJ-45 Gigabit Ethernet port, included DNTS Manager Centralized management software and a complete set of installation accessories (including a high-sensitivity time‑synchronization antenna, antenna feedline surge arrester, and more).

V. Customer Requirements

1. Must be implemented across the entire jurisdiction. 2855 a business outlet, 108 Ensure time synchronization across county-level legal entities and core business systems (including trading, risk control, log management, etc.), with terminal time deviations kept within the millisecond range to guarantee data consistency and transaction compliance.
2. The equipment must exhibit high reliability, support automatic switchover among multiple time sources, and incorporate fault‑tolerance mechanisms to prevent service interruptions caused by satellite signal outages or equipment failures.
3. Meets cybersecurity requirements of the financial industry, featuring identity authentication, access control, data encryption, and other capabilities to mitigate risks associated with time tampering and cyberattacks.
4. Adapts to distributed network architectures, supports concurrent access from tens of thousands of terminals, and is compatible with… IPv4/IPv6 Dual-stack and mainstream operating systems;
5. Provides intelligent operations and maintenance capabilities, supporting remote monitoring, log auditing, and tiered alerting to reduce manual maintenance costs.

VI. Solution

1. Core Equipment Deployment : Adopt DNTS-9 Type NTP Server, configured with dual satellite receivers and dual antennas, supports GPS / Beidou multi-system signal redundancy reception, with tracking sensitivity reaching - 166 dBm , ensuring stable signal acquisition even in complex environments; featuring a proprietary all-digital phase-locked loop and a self‑tuning algorithm, it automatically switches to a temperature‑controlled crystal oscillator (with an optional rubidium atomic clock) timing mode when satellite signals are lost, delivering timing accuracy better than 8.6us/day (The rubidium clock version is superior to 500ns/day ).
2. Redundant Architecture Design : Equipment配备 1+1 Hot-swappable dual power supplies with hot redundancy; supports multiple network interfaces on a single device. Bonding The function implements hot backup and simultaneously employs “ Core Layer - Access Layer ” In the secondary deployment mode, the core data center employs active‑standby hot standby with dual servers, leveraging virtualization. IP and heartbeat detection technology enable seamless switching, ensuring 7×24 Hourly continuous timekeeping.
3. Security Protection Configuration : Enable MD5/SHA Certification, AES/DES Encryption and RSA The asymmetric encryption mechanism supports user authentication and access control, while the management channel employs certificate-based encryption to prevent unauthorized access and data tampering. A leap-second smooth‑transition mechanism is configured to avoid system failures caused by abrupt time adjustments.
4. Intelligent Operations and Maintenance Platform : Deployment DNTS Manager Centralized management software, supports Web/SSH/SNMP Multi‑mode remote management enables real-time monitoring of the synchronization status of thousands of servers and tens of thousands of clients; it automatically logs time‑synchronization and alarm events, and supports… syslog/SNMP/email Multi-channel, tiered alerting and log retention to meet audit requirements.

VII. Implementation Outcomes

1. Time synchronization accuracy meets the standard: The time synchronization error of all terminal devices across the jurisdiction is kept within 0.03-2ms (Typical LAN values), time deviation of core business systems ≤10ms , fully complying with financial regulators’ requirements for transaction log timestamps;
2. The system operates stably and reliably: equipment MTBF reach 90000 Within hours of going live, the system achieved fault-free continuous operation and maintained high‑precision timekeeping even during satellite signal outages, with no service interruptions caused by timing‑synchronization anomalies.
3. Enhanced Security Protection: Multi-layered encryption and access control mechanisms effectively mitigate timing‑attack risks, with network security safeguards meeting financial‑industry standards and passing compliance assessments.
4. Significant improvement in operations and maintenance efficiency: Remote monitoring and centralized management capabilities reduce on-site maintenance workload. 70% , improved alert response efficiency 40% , annual operational and maintenance costs reduced 30% ; The system supports the access of tens of thousands of clients, ensuring it can meet future… 3-5 Annual business expansion needs;
5. XinChuang adaptation and compatibility: The product’s core components have been localized, ensuring compatibility with existing systems. IT The architecture and the indigenous innovation ecosystem lay the foundation for subsequent system upgrades.
