Time Distribution Model
Network time distribution systems use a hierarchical time distribution model, as shown in this
figure:
In hierarchical systems, primary time source clocks are Stratum 0 (zero), including GPS
satellites, National Institute of Standards and Technology (NIST) ACTS dial-up service, or
similar national time standards organizations.
The S100 acts as a Stratum 1 time server that derives its time from GPS and distributes this
time over a TCP/IP network using NTP. Stratum 2 NTP clients can distribute time to Stratum 3
computers.
