Abstract

The invention discloses a time synchronization method and system. The time synchronization method comprises the following steps of acquiring the original communication round-trip delay data, wherein the original communication round-trip delay data comprises the original round-trip delay time and the original time deviation, and the original round-trip delay time and the original time deviation are in one-to-one correspondence; fitting the original communication round-trip delay data, and determining a fitting slope and the fitted communication round-trip delay data, wherein the fitted communication round-trip delay data comprises fitted round-trip delay time and fitted time deviation; and synchronizing the local time according to the fitted communication round-trip delay data and the original communication round-trip delay data. By adopting the time synchronization method and system provided by the invention, the network time service precision and the time synchronization precision can be improved.

Description

Technical field [0001] The present invention relates to the field of communications, in particular to a time synchronization method and system. Background technique [0002] The Network Time Protocol (NTP) is a very widely used time synchronization protocol in the Internet. It was first proposed by Professor DLMills of the University of Delaware in the United States in 1985 and was designed and implemented. Its purpose is to adopt The local computer synchronizes the clock with the clock source to improve the accuracy of the local time so that different machines on the Internet can maintain a uniform and standard time, which is distributed to systems running in a variety of and extensive distributed network environments Accurate and reliable time information. [0003] Network time synchronization technology is constantly innovating. The early time synchronization technology required the establishment of a dedicated network to provide services for each system, and the cost was rela...
