Hi,

We’re looking at deploying PTP in our R&E network initially to provide an
alternative time source for our NTP service, but in the future we hope to
embrace other uses.

I’m wondering what level of interest there is in the perfSONAR community for
PTP support? The documentation talks of PTP, but the text was written a few
years ago where the technology was relatively new, and expensive, to deploy:
https://docs.perfsonar.net/ntp_overview.html
https://docs.perfsonar.net/FAQ.html

But now PTP is rather more mature, and support in devices better, and most
interestingly new Linux distributions include chronyd (which supports
hardware timestamps) rather than ntpd.

Our interest would be in enchanted accuracy for one-way delay measurements,
and thus the capability being added to owping.

Thoughts?

Tim
