摘要
研究当前仿真系统中的时钟同步问题和网络时间协议(NTP)。在NTP的基础上通过引入"主从服务器"模式、客户端时间推进和事件注册机制,实现一种适用于分布式仿真系统的、具有较高精度的软件时钟同步算法,给出同步系统的设计和实验方案。根据对实验数据的分析,验证该算法是一种简单有效的高精度时钟同步算法。
The problem of clock synchronization in the current simulation system and Network Time Protocol（NTP） are introduced in this paper. A software clock synchronization algorithm with high precision, which is realized by importing the mode of ＂master and slave servers＂ and the mechanism of time progress and event login in the client on the basis of the NTP is proposed. This algorithm is suitable for the distributed simulation system. The design of a time synchronization system and an experimentation are presented. According to the analysis of experimental data, the algorithm is validated simple and effective.
