随着互联网计算速度的提高、复杂性的提高并变得无处不在，对精确时间同步的需求也随之增加。在本文中，我们基于机器人最近收集的数据，描述了由网络时间协议 (NTP) 管理的时钟同步网络的特征，该网络由数千个节点组成，其中包括数百个 Stratum 1 服务器。 NTP 是 Internet 中最常见的时间同步协议。分析了定义计时质量的许多方面以及网络的拓扑特征。结果与 NTP 网络之前的特征进行了比较，显示了过去 15 年中时钟同步的演变。
As Internet computing gains speed, complexity, and becomes ubiquitous, the need for precise and accurate time synchronization increases. In this paper, we present a characterization of a clock synchronization network managed by Network Time Protocol (NTP), composed by thousands of nodes, including hundreds of Stratum 1 servers, based on data collected recently by a robot. NTP is the most common protocol for time synchronization in the Internet. Many aspects that define the quality of timekeeping are analyzed, as well as topological characteristics of the network. The results are compared to previous characterizations of the NTP network, showing the evolution of clock synchronization in the last fifteen years.
