Problems solved by technology

[0004] However, at present, a large number of devices only synchronize to one public NTP server or several public NTP servers, which may easily cause excessive pressure on the server and cause some synchronization failures

Embodiment Construction

[0042] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0043] The embodiment of the present invention provides a time synchronization method based on the NTP protocol, such as figure 1 As shown, the method performs the following steps:

[0044] Step 1: Open the NTP server and client at the same time on the default network device;

[0045] Step 2: According to the NTP server of the preset network device, time synchronization is performed on the front-end device of the preset network device in the local area network.

[0046] The working principle of the above-mentioned technical solution is: in the step 1, the preset network devices that enable the NTP server and the client at the same time are part or all of the networ...

Abstract

The present invention provides a time synchronization method and system based on the NTP protocol. The method performs the following steps: Step 1: Open the NTP server and the client on the preset network device at the same time; Step 2: According to the preset network The NTP server of the device performs time synchronization on the front-end device of the preset network device in the local area network. According to the method of the present invention, by providing the NTP service function by the preset network equipment, the pressure on the main NTP server is dispersed, and at the same time, the time synchronization function between each network equipment is realized to ensure the normal operation of each network equipment.

Description

technical field [0001] The invention relates to the technical field of digital information transmission, in particular to a time synchronization method and system based on the NTP protocol. Background technique [0002] There will be multiple devices working at the same time in the same LAN, and there will be continuous protocol interaction requirements during this period, which requires time consistency and accuracy between devices. Due to the different specifications of the time crystal oscillator of the device itself, the error gradually accumulates and increases as time goes by, which requires time synchronization. [0003] At present, NTP (Network Time Protocol, Network Time Protocol) technology is mainly used to solve the current clock synchronization problem of the Internet; wherein, NTP is developed by Professor David L. Mills of the University of Delaware in the United States, mainly It is a protocol used to synchronize the time of the computer. It can synchronize ...
