Hi all,

Short notes from the CCAMP microwave working group meeting 20 October.

Latest version of the draft is attached.

  *   A github for this work
     *   Scott presented the concept at the meeting – OK
     *   Local environments to be set up for those who would like to run the translations & validations
     *   https://www.rfc-editor.org/styleguide/<https://protect2.fireeye.com/v1/url?k=4e84d345-111fea74-4e8493de-86e2237f51fb-baf7a4ef203884ed&q=1&e=f7899998-d339-4286-a921-9706a55342de&u=https%3A%2F%2Fwww.rfc-editor.org%2Fstyleguide%2F>

  *   The draft has been updated to become the next version of the CCAMP draft
     *   Check the version number – 02 – Done!
  *   Need to review the draft in more detail and relate it to the use cases it is supposed to support
     *   Use the notes from earlier this year – 2021-02-03 as a reminder of topics discussed
     *   Check that text in draft reflects the fact that it contains three YANG modules - Done
     *   To what extent should the topology model show current values?
Changed very frequently – short time span – milliseconds
Will this info be used as a basis for the operations related to a topology, e.g. path selection?
Any input based on what other technologies have done? (Italo)
        *   Current coding & modulation? - Understand how it will be used? (Include - Jonas)
        *   Current signal condition? - Understand how it will be used? (Include - Jonas)
        *   Current bandwidth (=speed)? (Include, but make it generic - Jonas)
        *   Is there any other attributes that should be included for the same reason? (AP on all)
     *   Clarification of mw-bandwidth that is referred to the nominal-bandwidth (Jonas)
     *   Tx-enabled – Understand/describe if that can be supported by admin-status or not (Jonas)
        *   Tx-enabled is related only to transmission side, instead admin-status is the enabling/disabling of the complete carrier (including both rx and tx)
        *   Look at this in the overall context of how to make use of admin-status & oper-status for tps and links in te-topology.
        *   Bear in mind that links are uni-directional
        *   Link status = oper-status (relationship with carriers possibly in protected mode)
        *   Check the general relationship between status on tps and links (Italo)
           *   Link normally used (can rely on link in microwave) (explain in draft)
           *   TP used when inter-domain and link info not reported
     *   Bandwidth utilization (Daniela)
        *   Do nodes provide this info on a link/carrier level?
        *   How often do they change?
        *   Retrieve from node?
     *    Tx Power
        *   Use case for a topology model?

Next meeting October 27

Last day for submitting drafts in time for the next IETF meeting – October 25 (JonasA++)
