The following figure shows Primary time servers in various locations providing
time to their respective Secondary time servers. Secondary time servers, in turn,
provide time to their workstations.
Figure 1-47 Primary time servers
Use the Primary time server on larger networks to increase fault tolerance by
providing redundant paths for Secondary time servers.
If a Primary time server goes down, the Secondary time server can get the time
from an alternate Primary time server.
Place a Primary time server in each geographically distinct area so that
secondary servers and workstations can access them without using WAN links.
You must have at least one other Primary or Reference time server that the
Primary time server can contact. Whenever Primary and Reference time servers
are on a network, they must be able to contact each other for polling.
However, Primary servers do adjust their internal clocks to synchronize with
that common network time. Because all Primary servers adjust their clocks,
network time may drift slightly.
• Reference time server. Provides a time to which all other Primary time servers
and workstations synchronize.
