Re: [CCAMP] WG Last Call on draft-ietf-ccamp-flexi-grid-fwk-03 and call for sheperd

["Matt Hartley (mhartley)" <[e-mail]>]

All,

I've reviewed this revision of the document, and I think it's almost ready for publication. I have a few comments (below) but I don't think there's any major issues.

3.1: definition of OTN could be moved up to section 2.2, if you want.

3.2.1: you state that the Nominal Central Frequency Granularity is 6.25GHz, but there's no reference for this. I assume it's in an ITU doc somewhere? If so, it'd be good to say so (and where)

The document refers to "OTSi signals" in several places, but the definition of "OTSi" includes "signal" :) I don't know whether or not this is normal usage or whether it's worth fixing... but it looks technically wrong to me (like people talking about "PIN numbers" whenever they get cash out of the bank).

3.2.5, first bullet: "This group of OTSi should be carried over a single fibre." Is that a normal English should, or a 2219 SHOULD? If the former, it might be worth rephrasing to avoid ambiguity.

4.2: "The association of the three components a filter, a fiber, and a filter, is a media channel in its most basic form.". It'd be nice to clarify that this is a fiber with a filter at each end - that's not immediately obvious on first reading, especially with the diagram that makes it clear on the next page.

The paragraph below figure 8 is... unclear. Is it just trying to say that media channels can be joined together to make a new media channel? Or is there more to it than that?

Fig 12: OTSi trail? Did you mean OCh trail?

Fig 14: MLN/MRN needs explaining. Or removing.

4.3, towards the end: "there must be enough guard band between adjacent OTSis in any media channel to compensate filter concatenation effect and other effects caused by signal layer switching elements". Maybe "...to compensate for the filter concatenation effect and..." or "...to compensate for filter concatenation effects and..."?

4.8.4: bear in mind that 0 is not a positive integer, and it looks like the definitions involving (2^n) and (2^m) are intended to include the case where n/m is 0.

Cheers

Matt

All,
    Per below, I've been asked to call consensus on this, but there haven't yet been any comments received during the LC period -- which ends today.  So it's not too late to voice your opinion.

If you can, please review the latest rev of the document and comment.  Positive comments, e.g., "I've reviewed the latest version of this document and believe it is ready for publication", are welcome! This would be helpful, even from authors.  (Just saying "support" without review doesn't really serve the purpose.)

Thanks,
Lou -- as consensus caller "stuckee"

PS  I have reviewed this rev of the document and believe it is ready for publication.

Working group,

this starts a two weeks working group last call on draft-ietf-ccamp-flexi-grid-fwk-03.
The last call end on Monday May 11th. Please send you comments to the CCAMP mailing list.

All the IPR declarations from authors and contributors have been collected and can be found in the history of the document: https://datatracker.ietf.org/doc/draft-ietf-ccamp-flexi-grid-fwk/history/
Please note that no IPR was disclosed against this draft.

PLEASE NOTE

1.       Since both the chairs and the secretary are involved in the draft as co-authors, the consensus will be called by Lou.

2.       This is a good opportunity to have the WG involved also in the Post-WG Last call process nominating a document shepherd which is not one of the chairs or the secretary. The document shepherd:

a.       MUST NOT be one of the authors/contributors of the draft

b.      SHOULD be an expert of the ID subject

c.       Will receive all the needed support from the chairs.



Further details on the shepherd duties can be found in RFC4858 and at https://www.ietf.org/iesg/statement/document-shepherds.html:

Please volunteer if interested



Thanks
