Hello Daniele, chairs , WG,

I support the draft : it is in a good shape hosting all the common YANG entities (identity, grouping, etc) that can be used by any of the L0 YANG model we have in CCAMP.

Thanks
Sergio (as co-author)

Hi CCAMP,

-- IMPORTANT PREAMBLE--
We have two drafts which have a very good level of maturity, namely RFC9093bis and Optical Impairment aware topology.
The more we work on them and the more disparate use cases pop up. We requested the authors to have the drafts in a status that is "good enough" to address the vast majority of use cases supported by the industry today so that we can progresse the drafts to the next stage and not hold them potentially for ever.

With the actual version of the drafts we should be able to cover all of the use cases with only the following limitations:


  *   Homogenous muxponders: with the present version of the draft we are not able to support use cases of interoperability between muxponder of different versions, and we can use regenerator always at the lowest level (OTU) since we do not have client information when setting up a tunnel. This information is missing today.
  *   Client mapping compatibility: at the moment we can support optical compatibility with operational model, but we don't support client compatibility.

These use cases and others that might come to your mind, if really needed, can be handled by an update to the RFCs at later stages.
- END PREAMBLE --

That said, this starts a 3 weeks working group last call on draft-ietf-ccamp-rfc9093-bis-11.

The last call will last 3 weeks to provide more time for reviewing, given we're approaching IETF 121 meeting. It will end on Tuesday November 12th . Please indicate your support or concern to the mailing list. Review comments and nits are also welcome.
All the IPR declarations from authors and contributors have been collected and can be found in the CCAMP WIKI page: https://wiki.ietf.org/en/group/ccamp

If anyone is willing to be the shepherd for this draft, please feel free to volunteer (authors excluded).

Thanks
Daniele, Fatai, Luis
