IEEE1588授时系统同步性能的测试与分析

Testing and Analysis of Synchronous Timing System Performance Based on IEEE1588

由于许多应用领域对高精度网络时钟同步系统的需求,让IEEE1588标准精确时间同步协议(PTP)具有了巨大的发展潜力。该文首先对IEEEl588高精度时间同步的原理进行了阐述,然后分析了时间戳的生成方式。最后以自行开发研制的授时服务器和时间同步从设备为平台,测试与分析了软件时间戳和硬件时间戳下的时间同步性能。

With many application fields for precision network clock synchronization system requirements, so the IEEE1588 Protocol has great potential for development. This paper expatiates the principle of IEEE1588 precision time synchronization,then analyzes how the timestamp works. Finally, the time synchronization performance under software imestamp and hardware timastarnp condition is tested and analyzed on a time server and a time synchronization slave device.
