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!
