An IEEE-1588 compatible RADclock

Abstract : The RADclock is an open source software clock that is highly robust to latency variability. A limitation up to now has been that it could only be used with NTP servers, and was unable to take advantage of IEEE-1588 enabled devices, including PTP masters and NICs with hardware timestamping. This paper benchmarks an early implementation of PTP support for RADclock, with and without hardware timestamping. We evaluate performance under both nominal and stressed conditions against alternative software clients ptpd and timekeeper and find that it compares very well.
