Document: draft-ietf-ccamp-flexigrid-lambda-label-04 Reviewer: Robert Sparks Review Date: 2 Sep 2015 IETF LC End Date: 9 Sep 2015 IESG Telechat date: Not yet scheduled for a telechat Summary: Ready for publication as a Proposed Standard One thing I'd like to check, and I suspect this pokes at a conversation that has already happened (as hinted in the acknowledgements section): The discussion of managements systems having to deal with a 64 bit wavelength label caught my eye. This is an RFC3471 section 3.2.1.1 label isn't it? That document shows wavelength labels as 32 bit things. Has something updated 3471 to say to expect a multiple of 32 bits, and not 32 bits specifically? If not, maybe this document would be a good place to do so explicitly, rather than what appears to be fiat at the moment? micro-nit: at the end of the introduction "in that regard" suggests the document updates the work of the ITU-T in some other regard? I suggest simple deleting the phrase.
