A quick question related to this blog -

they mentioned that most modern NICs have hardware timestamp capabilities, that is consistent with what I saw. The question is what is the availability of those PTP ready & enabled routers/switches capable of acting as a Transparent Clock? I have two concerns, most of existing routers/switches are not PTP ready, even for those ones with PTP capabilities, its PTP related features may not be enabled in production. Any experience or numbers to share? thanks!

All recent data center switches I've seen advertise PTP; maybe it doesn't work when you turn it on though. Meta makes their own switches so they can enable and debug the software.
