The purpose of this document is to provide network and system administrators with a macro-guide to a high-precision PTP (Precision Time Protocol) network architecture. We will present a hierarchical, scalable PTP synchronization model that consists of three core levels of devices: the PTP Master Clock (Grandmaster), the PTP Boundary Clock, and the PTP Slave Clock.

rms 16
Indicates the "average synchronization error" in nanoseconds (ns).
This value reflects the overall level of stability of the time offset between the device and the master clock. rms 16 means that the average deviation is only 16ns, which is already very small and falls within the range of high-precision synchronization. The smaller the value, the more accurate the synchronization.

In a financial production network, time is not "as close as possible", but "must be consistent and traceable". When relying only on NTP, queuing jitter and path asymmetry across three layers and congestion can magnify deviations and tail risks to the millisecond-microsecond scale; PTP transforms source-to-end errors from uncontrollable fluctuations to budgetable, attributable, and manageable ones through hardware timestamps on the NIC/switching chip, boundary/transparent clocks, and (optionally) SyncE. PTP turns "source-network" errors from uncontrollable fluctuations into budgetable, attributable, auditable quantities of work through hardware timestamps on the NIC/switch chip and (optional) SyncE. With the T830 as the core, without interrupting the NTP of the existing network, the critical links are stabilized to the low-microsecond level first, and then tightened to the sub-microsecond/hundred-nanosecond level in the controlled core segments, so that minimal modification is made in exchange for maximum verifiability and compliance certainty.

This content is intended to serve as a reference for financial institutions, regulators and technology service providers in building time synchronization compliance. With the increasing frequency of global financial transactions, time has become an important infrastructure to ensure market fairness and compliance. Based on the regulatory standards of five global jurisdictions and domestic and international time system construction experience, this document systematically describes the technical architecture, regulatory requirements and compliance implementation path of time synchronization in the financial industry.

Beidou PNT in 2025 is upgraded from a single timing equipment vendor to an intelligent, localized and trusted PNT total solution provider. We will integrate AI + PNT, use blockchain to guarantee time credibility, and use multi-source fusion to realize centimeter-level positioning and nanosecond-level accuracy. In the future, we will adhere to independent control and internationalization, so that "China Time" can go to the world, and guard the safety and precision of every second.

T600-BDRBP NTP network time server can be widely used in government, national defense, finance, securities, insurance, mobile communication, cloud computing, e-commerce, energy and power, petroleum and petrochemical industry, industrial automation, intelligent transportation, security, smart city, Internet of Things and other fields.

T800 high-performance clock server can be widely used in government, national defense, finance, securities, insurance, mobile communications, cloud computing, e-commerce, energy and power, petroleum and petrochemical, industrial automation, intelligent transportation, security, smart city, Internet of Things and other fields.

T600-LBDRBP NTP time server supports NTP and SNTP network synchronization protocols, and it is a high-precision, large-capacity and high-security clock product. The hardware of the equipment adopts redundant architecture design, and the high-precision clock is directly derived from the atomic clocks of each satellite in the GNSS system, and the local clock source is tamed through the signal analysis, so as to realize the function of keeping the local clock accurately after the loss of satellite signals.

Extend high-precision time signals to ring network cabinets, column switches, smart meters, and edge sites to enhance fault location and non-intrusive detection capabilities.

Supports the time control requirements of wind power, photovoltaic, and battery storage systems in scenarios such as precise grid connection, synchronized back-feeding, and island switching.
