【摘要】：Network Time Protocol(NTP)是用来使计算机及网络设备时间同步化的一种协议,其目的是为各种网络设备提供高精准度的时间校正。伴随着高校网络设备数量爆炸式增长,我们所依赖的文件服务器、邮件服务器、互联网网关等诸多网络设备之间都需要一个精准的时钟作为信息共享的基础,因为数据共享、设备日志和网络安全是互联网上最常用也是最易遭受攻击的信息。为确保网络设备安全,网络工程师需要精准的时间确保这些应用及其它关键网络应用的安全。本文基于NTP协议网络应用时间戳同步机制的研究,可有效应用于高校网络中,使所有网络设备的时间戳具有高度统一性。所以在互联网中设计专门的时间服务器为需要精准时间的网络设备同步成为当今日益复杂网络应用环境的现实需求。
[Abstract]:Network Time Protocol is a protocol used to synchronize the time of computers and network devices, which aims to provide highly accurate time correction for various network devices, as the number of network devices in colleges and universities explodes. We rely on file servers, mail servers, Internet gateways and many other network devices that need a precise clock as the basis for information sharing, because of data sharing, Device logs and network security are the most commonly used and vulnerable information on the Internet. Network engineers need accurate time to ensure the security of these applications and other critical network applications. The research of timestamp synchronization mechanism of network applications based on NTP protocol can be effectively applied to university networks. So it is necessary to design a special time server in the Internet to synchronize the network devices that need accurate time. Therefore, it is a realistic requirement of the increasingly complex network application environment to design a special time server in the Internet to synchronize the time stamps of all network devices.
