Re: [CCAMP] Interim discussions on OTN slicing

Hi CCAMPers, Chairs,

Thank you for organizing and participating in the interim meeting for OTN
slicing. We have had some further discussions on the weekly calls and here
are the main points we draw from those discussions.



   - There is significant interest from the WG to progress the work for OTN
   slicing.
   - Most people believe the work for OTN slicing is consistent with the
   TEAS NS framework and is supported by the use cases described in the IETF
   NS framework as well as in this draft.
   - Most of the questions raised in the interim are not specific to OTN
   slicing but are more fundamental towards TEAS network slicing. The
   agreement from the interim, to our understanding, is to raise those
   questions to TEAS for addressing.
   - Since TEAS has already made the consensus to work on network slicing
   defined by the IETF NS framework, we think it is more appropriate for
   people who have concerns to challenge TEAS, as an individual, on those
   fundamental decisions. If TEAS decides to change the terms and scope on
   network slicing, then OTN slicing will follow suit and update accordingly.



Therefore, in our view a liaison to TEAS may not be needed at this
point. However, if the chairs consider so then we suggest to confirm that
our view is correctly aligned with the current TEAS work on network
slicing. Specifically,

   - Realization of slicing is not limited only to some specific
      technologies but also others such as OTN
      - The terms and modeling structure are aligned with the definition in
      IETF network slicing
