摘要
随着分布式系统的广泛应用,系统对高精度时钟同步的要求越来越高,在测控、通信等领域中已经对时钟同步提出了微秒级要求。为了达到微秒级时钟同步,首先概述了IEEE1588时钟同步的基本原理,其次对IEEE1588 v2.0进行了研究,主要研究了IEEE1588v2.0与IEEE1588 v1.0比较所引入的新技术、新方法。结果表明,v2.0比v1.0具有更高的同步精度,为以后的工程应用打下基础。
With the extensive application of distributed systems,the demand for high-precision clock synchronization system becomes urgent.Toreach the strict limit ofsome applications inspecial fileds,this paper first outlines the basic principles of IEEE1588 clock synchronization,then gives the second edition of IEEE1588,thenprincipally analyzes the new technologiesand methods of v2.0IEEE1588in comparison with v1.0 IEEE1588.Analysis indicates that v2.0 has much higer time precison,lays a foundation for future enfineering applications.
