摘要 随着信息技术和网络技术的发展,人们对时间同步的精度要求越来越高。网络时间协议(NTP,Network Time Protocol)是一种基于UDP的时间同步协议。介绍了NTP协议的基本原理,Y.1731单端DM原理。通过NTP协议在Y.1731报文中的应用研究和实践,使传统的网络时间同步精度能达到毫秒级别。实验数据表明,文中所设计的网络时钟同步系统比传统的时钟同步具有更高的时钟同步精度。 Network Time Protocol (NTP) is a time synchronization protocol based on UDP. With the development of information technology and network technlogy, people have an extremely strict requirement for consistency of clocks. This paper describes the basic principles of the NTP protocol, Y. 1731 single-ended DM principles. Through the NTP protocol packets in Y. 1731 applied research and practice, the traditional network time synchronization accuracy can reach milliseconds. The data measured shows that this synchronization system has higher precision compared with the traditional clock synchronization.
