8.3 NTP Hierarchical Structure
The NTP protocol supports a hierarchical structure to ensure the availability of time, allowing the
user to monitor their position in the hierarchy and thus the quality of the time service available.
Figure 2 – Explanation of Hierarchical Stratum Structure
The timeserver’s hierarchy is classed as Stratum, where a Stratum 1 time server that is directly
synchronised to a traceable standard source such as UTC. A server synchronised to a Stratum 1
server is classed as a Stratum 2 server, and so on. This hierarchical structure allows sub
partitioning of groups of networks.
Up to 512 Computers may synchronise to a single NTP80plus Time Server. We do not recommend
increasing the number of clients beyond this limit, as the performance will become degraded due
to non-responses.
