NTP Server – Using Stratum

• Using Stratums NTP (Network Time Protocol) is the most prevalent time synchronisation software available. On of the reasons NTP is so successful is the way it organises its clients into a hierarchy. The hierarchy of NTP is divided into stratum with each strata representing the distance from the original reference clock.  For instance an atomic clock that generates a UTC (coordinated universal time) signal is referred to as a stratum 0 device. A NTP server that receives a stratum  1 time signal is referred to as a stratum 1 device and a device that receives a time source from a NTP server is a ...
  
  
• Organising a Network Time Server Hierarchy Network Time Protocol is a hierarchical protocol which is divided into strata. Each stratum level describes the distance from the reference clock. An atomic clock that generates a time signal is known as a stratum-0 device.  A network time server that receives this time is known as a stratum-1 device. On a network a stratum 1 time server supplies the time to other devices on the network which are known as stratum-2 devices. Stratum 2 devices can be used as a time source and equipment that connects to them  to receive it become stratum-3 and so on. NTP can handle up to ...
  
  
• NTP Stratum Levels Explained Network Time Protocol is a hierarchical protocol and is divided into stratum which define the distance from the reference clock. A reference clock source that relays UTC (Coordinated Universal Time) time and has little or no delay is known as a stratum-0 device. Stratum-0 servers cannot be used on the network, instead, they are directly connected to computers which then operate as primary time servers. A primary server that receives a time signal from a stratum 0 device either through the GPS network or national time and frequency transmission is known as a stratum-1 device. On a network a stratum 1 ...
  
  
• Arranging a NTP Server Stratum Tree NTP (Network Time Protocol) is the most widely used time synchronisation protocol on the Internet. The reason for its success is that is both flexible and highly accurate (as well as being free). NTP is also arranged into a hierarchical structure allowing thousands of machines to be able to receive a timing signal from just one NTP server. Obviously, if a thousand machines on a network all attempted to receive a timing signal from the NTP server at the same time the network would become bottlenecked and the NTP server would be rendered useless. For this reason, the NTP stratum tree exists. ...
  
  
• Network Time Server – Introducing Stratum A network time server will synchronise all machines and devices on a network to UTC time (coordinated universal time). They are essential pieces of hardware in modern computer networks, without which, time sensitive transactions would be impossible. Most network time servers will use NTP (Network Time Protocol) to distribute a single UTC time source (Coordinated Universal Time) around a network. The way a network time sever synchronises devices is by allowing them to ask it the time (poll) if the device is slow or fast compared to UTC then NTP will advance or retreat the system clock. You would think that on ...
