My comment about draft-shmutzer-pals-ple

Christian and all,
My comment about the Private Line Emulation over Packet Switched Network draft<https://datatracker.ietf.org/doc/html/draft-schmutzer-pals-ple> at the PALS WG session this morning was about possibility of misleading d clock quality information that, IMH, is inherent for this proposal.

E.g., Section 1 of the draft discusses a use case about "two ethernet connected CEs and the need for synchronous ethernet operation between them without the intermediate PEs interfering or addressing concerns about ethernet control protocol transparency for carrier ethernet services". With Synchronous Ethernet, the information about the clock quality is carried in dedicated Layer 2 Control Protocol messages. If these messages are passed transparently they would potentially mis-represent the actual quality of the recovered clock.

I think that these considerations should be explicitly discussed in the draft, probably in the (currently missing) Applicability Statement section.
My comment should not be considered as preventing adoption of the draft as a WG document.

Regards,
Sasha
