Enabling Secure Network Time Protocol (NTP)

Figure 2-88. NTP Clock Stratum Levels

The devices at stratum 0 are GPS clocks or other radio clocks. These devices

are not attached to the network but are locally connected to computers.

Computers at stratum 1 are attached to stratum 0 devices. Stratum 1 devices

can act as time servers for timing requests from stratum 2 servers via NTP.

Computers at stratum 2 send NTP requests to stratum 1 servers. Normally, a

stratum 2 computer will reference a number of stratum 1 servers and use the

NTP algorithm to gather the best data sample, dropping any stratum 1 servers

that seem obviously wrong. Stratum 2 computers are peers to other stratum 2

computers, providing more stable and robust time for all devices in the peer

group. Stratum 2 computers normally act as servers for stratum 3 NTP

requests.

Computers at stratum 3 and higher employ exactly the same NTP functions

of peering and data sampling as stratum 2, and can themselves act as servers

for higher strata, potentially up to 16 levels (stratum 0 through stratum 15).
