NTP Overview

Network Time Protocol (NTP) is a protocol for synchronizing clocks on the network.

As the Internet develops, people have different requirements on time synchronization. Precise time is needed in real-time online transactions, manufacturing process control, time configuration on communication networks, network security design, distributed network computation and processing, transportation management, database management, and call records. However, when all the devices on a network need to be synchronized, it is almost impossible for an administrator to manually change the system clocks through command lines. This is because the workload is heavy and clock precision cannot be ensured.

To address the problem, NTP is introduced.

NTP is mainly used to synchronize clocks of all the devices on the network. You can configure NTP so that all the clocks on the network are synchronized soon with high precision, preventing errors and heavy loads of network administrators.
