精确时间协议（PTP）是一种设计用于在局域网上运行的高精度时间同步协议。PTP通常被称为1588，由IEEE标准1588 TM-2008定义。该协议理论上允许纳秒级的同步。在这个项目中，我们研究的环境中，多个1588设备通过网络连接，其中通常观察到的损害，在真实的网络中引入和非1588设备存在的协议的性能。通过观察对1588设备时钟同步的影响来评估性能。结果提供了有价值的洞察到现实世界的准确性和鲁棒性的协议。
Precision Time Protocol (PTP) is a high precision time synchronization protocol designed to run over a local area network. PTP, often referred to as 1588, is defined by the IEEE Standard 1588TM-2008. The protocol theoretically allows synchronization at the nanosecond level. In this project we study the performance of the protocol in an environment where multiple 1588 devices are connected via a network in which impairments that are typically observed in real networks are introduced and non-1588 devices are present. The performance was assessed by observing the impact on the clock synchronization of the 1588 devices. The results provide valuable insight into the real-world accuracy and robustness of the protocol.
