1.1.3 NTP Implementation Mode

To accommodate networks of different structures and switches in different network
positions, NTP can operate in multiple modes, as described in the following.
I. Client/Server mode
Filter and select clocks Filter and select clocks Filter and select clocks Filter and select clocks

II. Peer mode
In peer mode, both In peer mode, both
sides are synchronized sides are synchronized
to the clock with to the clock with
smaller stratum smaller stratum
Figure 1-3 NTP implementation mode: peer mode
In peer mode, the active peer sends clock synchronization packets first, and its peer
works as a passive peer automatically.
If both of the peers have reference clocks, the one with smaller stratum is adopted.
