18:30   Introduction, NMRG Chairs

18:35   IRTF and NMRG in a nutshell, NMRG Chairs
- Jérôme presented the slides.
- Olga: Status of the RG documents after RG last call?
- Both drafts are with the RG chairs for Shepherd review write-up
- Laurent: this is in my todo list and it will come soon.
- Stefan Schneider: Is there any timeline or plan on how/when to proceed with
the Google doc on AI for NM? - Jérôme: Yes, soon.

19:00   Distributed and zero-touch management of Network Slices in beyond 5G,
Amina Boubendir
                https://www.monb5g.eu/
- Phil: could you say more about the machine learning in the project, what is
it that it's learning? what choices it is making? I understand it is related to
slicing but didn't get it fully - Amina: Dealing with resource allocation and
placement. Main proposal is using DRL algorithm, that separates the domain. How
each domain allocates the ressources separately. Control by heuristics, to
optimize the orchestration the placement of network slices. DRL agents in each
domain and central agent to allow gaining an end-to-end view. Automated feature
extraction from the infrastructure, and it learn how to orchestrate.

19:30   Concepts of Digital Twin Network, Diego Lopez
                https://datatracker.ietf.org/doc/draft-zhou-nmrg-digitaltwin-network-concepts/

- Laurent: The content of the presentation is on the draft or a it is a list of
challenges? - Diego: We would like to see collaborations. Considering the
draft, there are some guidelines, but we are not able to meet all until now. -
Jérôme: - Diego: This should be one of the goals of the digital twins.
Specially, the idea of injecting some traffic and control conditions that mimic
the real behavior of real users. We try to in some cases to predict, lets say,
running 25 networks and see what happens. - Jérôme: Is is possible to predict
using inputs as maximum and minimum? - Diego: Once you are able to mimic, we
will be able to identify patterns. - Franco: We have a similar concept, we are
interest to see how we can frame this and talk more about it - Diego: It would
be nice, we would like to talk to people that work closely to ours. - Franco:
More related to network security.
