ptp4l –version “` **配置Linuxptpd** 1. 创建一个ptp4l的配置文件,命名为ptp4l.conf: “`shell sudo nano /etc/linuxptp/ptp4l.conf “` 2. 在配置文件中添加以下内容: “`shell # 设置PTP模式为单主模式 ptp4l -m -H -i <网卡名> # 设置PTP模式为多主模式 ptp4l -s -i <网卡名> ...
LinuxPTPd是一个基于PTP(Precision Time Protocol)协议的时间同步软件,可以实现微秒级别的时间同步,特别适用于要求高精度时间同步的场景。LinuxPTPd的原理是通过在局域网内的各个节点之间进行时间同步,以实现整个系统的时间同步。 使用LinuxPTPd进行时间同步的过程并不复杂。首先需要在系统中安装LinuxPTPd软件包,然后进行一些...
时间校正:从时钟根据计算出的时钟偏差和路径时延,对本地时钟进行校正,从而实现与主时钟的时间同步。 ptpd时间同步的配置与使用 安装ptpd:在Linux系统中,可以通过包管理器(如apt-get)安装ptpd软件包。 配置ptpd:创建并编辑ptpd的配置文件,设置PTP模式(单主模式或多主模式)、网络接口等参数。 运行ptpd:启动ptpd守护进...

Linux has a PTP kernel API but not all hardware supports it. Because PTPd supports multiple OS platforms, where hardware timestamping may use different mechanisms on every platform, it has to be re-written in a modular way to allow this without unnecessarily increasing code complexity, which ...
SERVICE MANAGEMENT The operation of ptpd is managed as a service by the service management facility, smf(5), under the service identifier: svc:/network/ptp:default Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). The...

IEEE1588定义了一种精密时钟同步(PTP)协议,广泛应用于分布式测控系统中。PTP协议可以通过纯软件或者纯硬件的方式实现。纯软件方式可采用开源的PTPd代码,开发简单,协议实现完整,但只能达到毫秒级同步精度;纯硬件方式通过硬件编程实现,同步精度可达纳秒量级,但是开发难度大。在开源的PTPd的基础上,保留协议上层部分,底层则采...
