IV. Purchased Products

NTP Server (Model: DNTS-9 )

V. Customer Requirements

1. The time synchronization accuracy of the core business system must meet financial‑grade standards, ensuring timestamp consistency across critical scenarios such as high‑frequency trading and risk management compliance.
2. It features autonomous and controllable capabilities, leveraging domestically developed core components to ensure the timing system’s security without relying on external dependencies.
3. Supports multi-source time input (Beidou) and features a redundant design to prevent service interruptions caused by single-point failures.
4. It is compatible with existing distributed network architectures, supports the simultaneous access of hundreds of thousands of terminal devices, and meets the scalability requirements of all business lines.
5. Provides visual monitoring and remote management capabilities, reducing operational costs and ensuring… 7×24 Stable operation for hours.

VI. Solution

Beijing Zhongxin Chuang, in response to Huatai Securities’ core requirements, has customized a solution based on… DNTS-9 Type NTP Server-centric time synchronization solution:

1. Hardware configuration: Utilizes a Hygon-based processor, paired with a domestically developed operating system, and incorporates core components. 100% Domestication, meeting the requirements for independent and controllable operations;
2. Time‑synchronization architecture: Supports BeiDou satellite time synchronization; offers an optional standalone BeiDou time‑synchronization mode; and is simultaneously compatible with… IRIG-B code, 1PPS+ToD Upon receipt of the ground‑based time source input, multi‑source redundancy and backup are achieved through priority configuration.
3. Accuracy Assurance: Equipped with a high-performance rubidium atomic clock, it can maintain operation when satellite signals are lost. ≤500ns/24 High-precision timekeeping at the hour level, with terminal synchronization accuracy within the local area network reaching 0.03~2ms ；
4. Expansion Capability: Configuration 4 RJ-45 Gigabit Ethernet interface, supports NTP Throughput ≥400,000 Next / seconds, meeting the needs of massive terminal access;
5. Operations and Maintenance Support: Included DNTS Manager Centralized monitoring software, providing Web 、 SNMP 、 Syslog and various management methods, supporting fault alerts and remote configuration, paired with 7×24 Hourly technical support service.

VII. Implementation Outcomes

1. Time synchronization accuracy meets the standard: The time deviation at key nodes, including Huatai Securities’ core trading system, risk control system, and data center, is maintained at the microsecond level, fully satisfying regulatory requirements and business‑collaboration needs.
2. System stability improvement: Mean Time Between Failures ( MTBF ) Reach 90,000 Hours, a multi-source redundancy design ensures uninterrupted timing services even under extreme conditions;
3. Implementation of Independent and Controllable Solutions: Domestic software and hardware architectures have passed compliance assessments, ensuring the security of core information systems.
4. Operational Efficiency Optimization: A visual monitoring platform enables end-to-end status tracking, while remote management capabilities reduce on-site operational costs. Since deployment, no time-synchronization-related incidents have occurred.
