摘要
IEEE1588通过定义基于消息的精确时间同步协议PTP,提供了一种解决以太网实时性不足的有效方法。在分析IEEE1588时间同步机理的基础上,依据同步消息的传递路径,从端节点和交换机两个方面对其典型的实现方案进行了归纳总结,并进行了同步性能比较。
By defining the precise time synchronization protocol PTP based on message,IEEE1588 provides an efficient method to solve real-time insufficiency of Ethernet.This paper analyzes the synchronization mechanism of IEEE1588 in the foundation,according as the transmission path of synchronization message,the typical scheme is summarized from node and switch two aspects,also their synchronization performance is compared.
