Hi, Greg,

Hi Spencer,
thank you for your thorough review and the question.
NTP yet doesn't use transparent clock paradigm but in section 3 G-ACh for
Residence Time Measurement we've noted that NTP may be one type of TLV and
have requested appropriate allocation by IANA in the new sub-registry MPLS
RTM TLV Registry (section 7.2). Thus, if NTP will be enhanced to use
transparent clock, the RTM over MPLS will be capable to support it.
We're open to your suggestions to make it clearer.


So, is it correct to say that PTP is the only time protocol that uses the
transparent clock paradigm today?

Spencer

Kind regards,
Greg
