摘要： 讨论了分布式系统中时钟同步的系统模型、远端时钟读取方法以及双向通信传输过程,给出了3种不同的时钟同步方案。同时,对基于多次同步消息的冗余传输,提出了新的基于统计平均的时钟同步算法。通过多步时间传输协议,在较短同步周期内对时钟进行同步。

Abstract: System models of clock synchronization, remote reading methods and bi-directional transmitting process in distributed systems are discussed. Three different clock synchronization schemes are given. Based on redundant transmitting of multiple synchronizing messages, an algorithm of clock synchronization using statistical mean is proposed. Through multiple times transmitting protocol, clocks get synchronized in a shorter period of synchronization.
