Abstract

The time synchronization is very important for network testing that is at a long distance. For time synchronization, two different network testing apparatuses uses a network time protocol (NTP) or a geographic position system (GPS). For using GPS with less timing error, an expensive GPS antenna needs to be installed outside the door. NTP is through the network. The network itself causes a time delay and the error in the time delay of the network occurs. So, NTP has not been used to measure a high speed network. This paper has been made in an effort to provide a network testing system using a Standard Wave to facilitate time synchronization with at least two network testing apparatuses, and an operating method thereof. The Standard Wave has extremely little time error. It helps to perform accurate testing.

基于标准波的网络测试系统时间同步方法
对于远距离网络测试来说,时间同步是非常重要的。对于时间同步,两个不同的网络测试设备使用网络时间协议(NTP)或地理位置系统(GPS)。为了使用定时误差较小的GPS,需要在门外安装昂贵的GPS天线。NTP通过网络配置。网络本身造成时延,导致网络时延误差。因此,NTP还没有被用来测量高速网络。本文旨在提供一种使用标准波的网络测试系统,以方便与至少两台网络测试设备进行时间同步,并提供一种操作方法。标准波具有极小的时间误差。它有助于执行准确的测试。
