AN NTP STRATUM-ONE SERVER
FARM FED BY IEEE-1588

For the past 16 years, USNO?s 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 GrandMaster/Slave
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
