Agenda:

09:30 Introduction, RG Chairs, 10 min

• Two RG documents in last call will proceed to IRSG review. 2-weeks
  call for comments for draft-irtf-nmrg-ai-challenges

Status of documents
Next meetings
09:40 Deakin Internet Research: Unlocking the Potential of Zero Trust
SemCom Networking, Shiva Pokhrel 20 min

• Q-Diego L.: semantics more linked to ICNRG than NMRG
• Q-Jerome F.: You apply DRL. Can you transfer the learned policy to
  another agent/domain? to avoid re-learning

10:00 - 10:10 Joint Exposure of Network and Compute Information for
Infrastructure-Aware Service Deployment,
https://datatracker.ietf.org/doc/draft-rcr-opsawg-operational-compute-metrics,
Jordi Ros Giralt, 10 min

• Q ?: The problem is the same for transfer of compute within or
  between administrative domains. Between administrative domains you
  add more layers.

  • A-Jordi: here the use case is for the same operators but with
    multiple operators it adds complexity. Need to migrate complete
    workload to maintain low latenecy.

• Q-Danyang: work seems relevant to CATS. Wondering why not presented
  there?

• Q-Colin: good to disucss the work widely. A lot of related work at
  IETF like CATS. The developmenet of standadize metrics should happen
  in standardization organizations, not research group.

10:10 - 10:50 Intent-Based Networking, 40 min
Network Management Intent, One of IBN Use Cases,
draft-chen-nmrg-ibn-management, 10min, Danyang. Chen

• Jérôme: please share link to the IBN demo on the NMRG mailing list

Interconnection Intents,
draft-contreras-nmrg-interconnection-intents-04, 10 min, Paolo Lucente

• Q-Qin W.: include TMF in the list of groups
• Q-Jordi R. G.: slide 2/3 how to ensure interactions will happen
  across providers nd can yo uelaborate that in a use case.
  • Paolo: two main use cases between providers: peering
    interconnection between OTT and a cloud provider (between
    providers), 5G use case within the same provider but different
    domains (access and edge for example)

An Intent-Based Management Framework for Software-Defined Vehicles in
Intelligent Transportation Systems,
draft-jeong-opsawg-intent-based-sdv-framework-00, 10 min, Jaehoon Paul
Jeong

Summary of the side meeting on IBN, RG chairs, 10 min

• Paul: having subsection for explaining use cases like network
  planning, network construction. Merge draft hopefully for IETF 120.
  First step: finalize authors and contributors
• Laurent: remark 1: seek alignment on terminology. remark 2: what
  could/should be the research outcome of the IBN use cases. There is
  value in each use cases, probaly also differnet cvalue in the set /
  across use cases. How the work in NMRG on IBN use cases progresses
  the SOTA.
• Diego: integration of IBN and AI Ok. with green unclear, do not see
  the connection.
• Colin: gaining insights from the use cases. learning from them.

10:50 - 11:20 Network Digital Twins, 30 min

Network Digital Twin: Concepts and Reference Architecture and processes
to progress on this draft, draft-irtf-nmrg-network-digital-twin-arch-05,
Cheng Zhou, 10 min.

Feedback from the NMRG participants on the draft in regards to its
intrinsic content and the forseen future work on NDT in the group, 20
min

• Chris: improvment on the concepts. talking about functional parts of
  NDT or applications of NDT. cf. inner-outer closed loops.
• Chris: even if we spearate concepts from architectures, at least
  keep the different digital twins types or use cases of digital
  twins. No disagreement on fundamentals, the key difference is how it
  is use wetehr there is an intenet transaltor...
  -[essentially, get the right distinction of what the NDT
  architecrure scope and purpose are]
• Colin: focus on what indusrty and other SDOs are doing. remind this
  is a research group. The goal is not develop reference architecture.
  focus on research questions and not engineering ones. Engineering
  should go to IETF. focus on research papers, research output.

11:20 - 11:30 Telemetry Methodologies for Analog Measurement
Instrumentation, draft-janzking-nmrg-telemetry-instrumentation-01,
Christopher Janz, 10 min

• Q-Colin: similarity with real-time streaming. should have a look.

** Side meeting minutes **

Minutes:

• Presentation Intent Translation Engine, Paul

Alex - Can the proposal provide feedback to the user and apply to the
closed loop control?
Paul - It does not include closed loop control..(...) to use RFC Intent
life cycle.
Alex - CMS uses API to communicate with the Infrastructure manager or
other method?
Pedro - CMS to VIM is a way, but also it can be used with Open source
MANO. It is also necessary to identify which structures need to be
extended in order to address them.

• Discussion on IBN use cases, Kehan

Jérome - I appreciate a way to integrate the use cases. You could try to
write a small example of how the section should be considering the other
drafts.
Paul - We will try to discuss with other authors. (...) WE can take 2
editors and put other authors as contributors.
Kehan - We can negotiate with authors of other drafts.
Jerome - There are some use cases that we don't have at this moment, for
example a security one.
Kehan - Usually, in use cases , it is possible to have editors and
others cabe be made as contributors.
Jeferson - We could ask authors if they agree to integrate the drafts,
maybe in a meeting.
Jerome - Of course, we do not obligate the integration. We will bring to
the list, not all authors participate in the meetings.

Jerome - It is important to define what is the level and time frame of
the use cases. description.
Diego - It is important to identify the different perceptions of what
has been done in WGs. How can we support what.
Paul - We need to analyse the gap of the user cases and the differences
from what was done in other groups.
