Getting the Time from Remote NTP Time Sources

Run the DTS server with the NTP time-provider (dts_ntp_provider.c) on a node with access to an NTP server. Specify the inaccuracy in a manner that is consistent with local NTP experience.

Observe the following advisories:

· Advisory - If links to remote sources are distant, consider having one of the subnetwork nodes run the NTP locally.

· Advisory - Note that the NTP time-provider does not accept time from an NTP node at Stratum 8 or higher.

· Advisory - The NTP node needs to be as close to Stratum 1 as possible.

The following figures both show a DTS server getting the time from a remote NTP time source, which is a Stratum 3 server. However, in the first figure (Scenario 1), all of the advisories in this topic are followed; in the second figure (Scenario 2), the first advisory, running NTP locally on one of the subnetwork nodes if the link to a remote source is distant, is ignored.
