摘要: 时间同步是现代通信网络中必须解决的重点问题之一。论文分析了某些特殊场合NTP协议难以满足同步需求的原因,提出了一种改进型NTP协议,并构造出IP网络时延模型,对协议算法进行仿真和分析,总结出该协议的应用条件。

关键词: 时间同步, NTP, 点对点, 仿真

Abstract: The time synchronization is an important problem which should be solved in the modern communication networks.In this paper,a special requirement about time synchronization is taken up,and can’t be met by NTP.Then,an improved NTP protocol is offered.In order to test its practicability,we gave the simulation and analysis,and summarized the condition for application.

Key words: time synchronization, NTP, point to point, simulation
