Attendees

  *   Nagendra Kumar
  *   Diego Lopez
  *   Benoit Claise
  *   Marisol Palmero
We got declined:

  *   Eric Vyncke
  *   Shwetha Bhandari
  *   Camilo Cardona
Meeting notes/updates:

  *   DMLMO v03 submitted for IETF v03:

  *   “hierarchy” concept: Asset/subasset, feature/subfeature, license subasset
  *   Cross reference between the modules: 1:1 or 1:N
  *   In this cross reference, the modules can be augmented
Benefits: Capability of extention, integration, flexibility, scalability

  *   License Use Cases, might be challenging to cover multivendor scenario. Together with Camilo and Shwetha, we are working on it, and even we know we will not be able to cover all scenarios, we want to demostrate that we can cover some initial scenarios and demostrate on it.
  *   New Organization/Service and User modules have been included in the current draft, being considered as a proof of flexibilty and scalability.

Next side meeting is scheduled during IETF 113 event. I check with individuals, as not everybody will be onsite. But it will be good to have sometime together before  Thursday OPSA meeting slot.

Many Thanks,
Marisol

Hi,

DMLMO side meeting today has got a reduced audience, due to other priorities.
It was a short call and here are the notes:
https://notes.ietf.org/s/jEUXpW1XR

** IETF DMLMO side meeting (Feb/23)

Attendees

Eric Vyncke
Marisol Palmero

We got declined from:

Luis M Contreras
Diego Lopez
Camilo Cardona
Frank B.
Shwetha

Meeting notes:
* As we talked during previous meeting, we are considering to add a more flexible data structure, not only to cover "organization" attribute in asset(s) module; but also to be considered on the original "asset", "license" and "usage" containers. In this way, we will have a flexible and recursive implementation where there is introduced a more flexible model to cover this concept of parent-child/hierarchy (referred as "sub-asset", "sub-license", "sub-feature") as considered in the current DMLMO YANG modules.

* Together with Shwetha and Camilo, we are reviewing how licenses will iterate through feature-usage and asset(s), currently work in progress,  we will provide an update during next call.

* In order to present and update in the coming  OPSAWG IETF 113 meeting, we are looking to submit a new release for the DMLMO draft by end of next week.

* For next IETF 113 event, it will be good to know how many people with interest on DMLMO will be present during that Wednesday-Thursday in Vienna. Still considering to be onsite, but it might be a good opportunity to have a life discussion during that week.

Many Thanks,
Marisol

  *   Meeting notes:
  *   Agreed that meeting will be moved to 15:00 CET
  *   Quick intro from the different participants (this will be done just for this first meeting)
  *   Review Current YANG modules attributes - Marisol to list a few changes for next call including:
     *   Address for assets (MAC/IP), with purpose being management of the asset
     *   Organization - Consider organizational hierarchy. Marisol to prepare a proposal for next call
  *   Licenses - Camilo
     *   Considering additional attributes for licenses to cover “combo” options for feature&assets, including a possible concept as “License Catalog” notes:
     *   Benoit & Eric: Licensing is a complex topic.
     *   Camilo: Intention is to simplify the complexity: focusing on "Feature to a license" vs "Asset to a license"
     *   Diego: I believe the licensing model is very much connected with granularity
  *   Lifecycle for (V)NF vs YANG modules (OSM) - Diego
  *   Tracking table in ppt: Marisol to create Tasks for each topic and include:
     *   Evolve attributes for “Assets in use”
  *   RoundTable
     *   Luis: Review HW and SW disaggregation
     *   Inventory Management, discussing 2 options:
        *   as per IETF112 OPSAWG discussion, we can raise topic to the chair and propose a follow up conversation.
        *   review DMLMO current model how an asset is defined, and the attributes linked to it. Review the concept of asset definition and how it links to inventory. We will address this in next call
thanks,

Marisol Palmero

Initial list of topics to review & discuss:

* "Organizations" in YANG
* Licenses linked to Features vs Assets/ License “Catalog”
* LifeCycle for (V)NF vs existing YANG modules
