Hi Manav et al.
A few comments/questions:
Section 2. Terminology:
* TC: Transparent Clocking --> Transparent Clock
* PTP PW:
Should the text read: A PW within a PTP LSP that is dedicated to carry
PTP messages ?
That at least is my understanding of the PTP PW.
Put another way, can you have an Ethernet PW that is sometimes carrying PTP,
sometimes "data"?
More general, mustn't all labels in the stack (apart from reserved labels) be
PTP labels?
* CW: duplicate
Section 5
* Figure 1+2: should top label read "PTP label", ref. section 4?
* For my understanding: the range of PTP reserved labels, is that defined by
the operator?
Section 15
* last paragraph says:
"The use of Penultimate Hop Pop (PHP) is acceptable as long as either
the PHP label is the bottom of stack label (applicable only to UDP/IP
encapsulation) or the label below the PHP label is a PTP label."
This implies that the PHP-label is also a PTP label, right?
A more general comment: would you agree that there is a general class of tunnel
technologies
(PBB, MPLS, IPoverIP) that share the problem you have described here, and to
which you found a solution for MPLS?
Thanks,
Lars

Hi Tommy,
This is a typo and will be fixed in the next revision.
