***
10 min. – RG  news and next meetings/events
Monitoring the situation about IETF 107 maintained or cancelled.
Recent updates on preparation of the IBN IETF 108 hackathon through discussion
with Walter C. and Barbara M. on joining their implementations. Also involving
Nokia (Fred) and UFRGS (Lisandro). Further work needed but first actions
started.

***
45 min. - draft-li-nmrg-intent-classification, Olga
Laurent: on the methodology, not necessarily a full-fledged taxonomoy
methodology required. important to describe the methodology used to derive the
classification (criteria used, how defined. the sources of inputs (litterature,
use cases...). methodology is important as a rigorous scientific approach to
classification, and long-term value : for example if someone lese comes later
with other use cases, or intent types, how can she/he maps their inputs to the
classification. this bring long-term evolution and value to the work. Olga: on
intent definition: many stakeholders. Even if agreed generic definition, it's
valuable, as a starting point. Laurent, Olga: bring the draft to the NMRG
GitHub page, as individual repo. Will: Author from CT, couldn't join the
virtual meeting, but will send comments to the mailing list.

***
10 min. - draft-irtf-nmrg-ibn-concepts-definitions – Laurent
Laurent: revisions being finalized among authors: general edits, updates to
lifecycle diagram, fixing the definition, new security considerations. Target:
new version before IETF 107 deadline.

***
30 min. – Slice management automation and SLA compliance : forerunner of an
IBN-based slice exposure, Amina
Laurent: for e2e network slicing, do you consider ONAP to be the only domain
manager or there could be other platforms? Amina: ONAP could act as
multi-domain orchestrator or the NS manager could interact with other
orchestrators (cf. EVE project) Olga: not looking at FG (Forwarding Graph)?
Only VNFs and NS (set). Amina: yes. Only considering a single FG. Laurent:
could link to work from Sabine and Fred on Intent for NS. Also interesting
functionality of the "capability exposure" to support the intent mapping
functionality in knowing how to match certain parts of he intent to the
underlying infrastructure capabilities. Olga: considering only NS, not other
types of intent (operator, maintenance…). Amina: priority on NS and capability
exposure.

***
AOB
Update on AI for Network Management Research Challenges document
Jérôme: goal is to produce a document listing research challenges. Several
expression of interests made and synthesis of challenges in previous meetings.
Will make document and approach available Laurent: should give possibility to
easily contribute and give inputs/feedback, and also visibility e.g. in the
form of an I-D.
