基于Internet的测试网时间同步问题的研究

Research of Time Synchronization of the Test Network Based on the Internet

时间同步是构建分布式测试网络最重要的基础技术之一 ,它在以Internet为基础构建的测试网络中显得尤为突出。本文介绍了现有互联网上的一些网络时间协议 ,提出了几种解决测试网时间同步问题的方法 ,并对这几种方法进行了比较。通过试验和实际应用的检验 ,这些方法是切实可行的 。

Time synchronization is one of the most important primary technologies in building the distributed test network.This problem seems more significant in the test network based on the Internet.This paper introduces some network time protocols running on the current Internet,brings forth several methods which can solve the time synchronization problem of the test network,and compares these methods.The testing result and practical application prove that these methods are feasible and the timing precision reaches general networked test criterion.
