pmc (PTPManagement Client) Send PTP management messages to PTP nodes 如果对内部的实现协议感兴趣,可以见下面链接,以及未来的总结。 IEEE1588 ( PTP ) 协议简介www.cnblogs.com/adaminxie/p/6754644.html 从时钟得到4个精确的两个报文的收发时间,就可以计算出相应的offset与delay来了 注:PTP并没有介绍...
LinuxPTP provides the four user applications - ptp4l, phc2sys, hwstamp_ctl and pmc. The definition and usage of these applications is as follows: ptp4l: It is the main program that implements the Precision Time Protocol (PTP) according to IEEE standard 1588 for Linux, as a Boundary Cloc...

3.端口0是用于本地PTP管理的Unix域套接字。端口1是eth0接口; 4.当从端口状态改变UNCALIBRATED到SLAVE时,计算机已经成功地与一个PTP主时钟同步。 软件时间戳就介绍这些,命令“pmc”我不了解,所以就不记录了,等单位要真是买来硬件服务器,我再来记录硬件时间戳模式。

Because of the implementation of the UDS module, it is not possible for a process to act as both a PTP management client (PMC) and server. Going forward, one ptp4l instance will need to subscribe to another using the PMC methods. Pave the way by allowing the interface to include an ...
