摘要
实现分布式系统时间同步的方法有两种 :一是将外部时间基准引入分布式系统的绝对时间同步 ,二是仅在分布式系统内部使用算法实现同步的相对时间同步。本文详细讨论了适用于局域网的各种时间同步算法 ,并对部分算法的应用结果进行了分析。
There are two kinds of implement method of time synchronization:the absolute time synchronization and the relative time synchronization, the former needs an external time to be as a Primary Reference Source(PRS), the latter can be realized only by executing synchronization algorithm inside the distributed system. In this paper, some time synchronization algorithm which can be used in LAN are discussed in detail, analyses of application result of some algorithm are given, too.
