Announcement made. *** 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.
