| 摘 要： | 基于IEEE1588标准,介绍了精确时钟协议的时钟类型与报文种类。分析了主、从时钟间采用同步报文实现时钟同步的机制,以及同步间隔与网络负荷、同步精度之间的关系,指出了同步紧随报文的作用和使用条件。给出了报文时间标记点在以太网中的准确定义、PTP子域到以太网多播地址之间的映射和PTP报文到以太网报文之间的映射,提供了精确时钟同步协议在以太网中实现的具体方法。

| Abstract: | Based on IEEE 1588 standard,the clock types and message types of precision clock synchronization protocol were introduced.The mechanism of clock synchronization implemented by using synchronization messages between master and slave clocks was analyzed.The relationship among synchronization interval,network traffic load and synchronization accuracy,was analyzed too.The function and usage qualification of Follow_Up message were pointed out.The exact definition of message timestamp point,the mapping of PTP sub... |
