Abstract:

For the past 16 years, USNOs Network Time Protocol NTP stratum-1 servers have been synchronized to its Master Clocks via IRIG-B time code on a low-frequency RF distribution system. The availability of Precise Time Protocol PTP, IEEE-1588 host-based interfaces will enable the deployment of NTP servers fed by IEEE-1588 over conventional Ethernet networks. This paper describes a PTP GrandMasterSlave network which maintains synchronization of internal stratum-0 NTP reference clocks to within tens of nanoseconds. The configuration of a PTP network and the effects of various PTP configuration options are demonstrated.
