1. Overview of NTP Synchronisation

NTP (Network Time Protocol) is a protocol designed to synchronise computer clocks. It enables computers to synchronise with their server or clock source, providing highly accurate time correction while employing encrypted authentication to prevent malicious protocol attacks.

An NTP network clock refers to a timepiece receiving time signals via the NTP protocol and network transmission. It receives standard time signals from satellites via a GPS timing antenna, which are then transmitted to an NTP network time server. After conversion by a switch to generate standard time signals, these are transmitted via network cables to NTP network slave clocks, synchronising them with the NTP time server.

2. Applications of NTP Network Clocks

(1) Various time synchronisation systems acquiring standard time via satellite synchronisation;

(2) Applications in institutions such as hospitals, educational establishments, and government service centres;

(3) Large-scale areas including hotels, office buildings, transport terminals, airports, major factories, and schools;

(4) Systems for e-commerce platforms, B2B online systems, and database preservation and maintenance;

(5) Computer networks, computer application systems, and process control management systems.

3. Advantages and Disadvantages of NTP Synchronisation

Advantages: NTP synchronisation clocks offer high timing accuracy, stable signals, precise timekeeping, user-friendly operation, and synchronous operation. Systems incorporating built-in NTP protocol reception modules further emphasise simplicity of operation, quality, and operational reliability. NTP synchronisation clocks can fully utilise existing local area networks; Ethernet equipment is mature and straightforward to implement. Furthermore, NTP synchronisation clocks can fully utilise the TCP/IP protocol for data communication, facilitating clock monitoring.

Disadvantages: NTP synchronisation clocks require cabling, and the need to procure servers results in higher cost budgets. Additionally, wired connectors can sometimes introduce unreliability. As different system manufacturers optimise and configure NTP according to their own system requirements, compatibility with other systems must be considered.
