Master at: https://notes.ietf.org/notes-ietf-123-anima
IETF123 is a hybrid IETF meeting.
Please familiarize yourself with the new&changed procedures for
participating in-person or remote:
https://www.ietf.org/how/meetings/preparation/
ANIMA will have one ~2 hour session,
chaired by Sheng Jiang and Toerless Eckert, Monday, Session III, "El
Escorial", 14:40 - 16:30 Meeting Time UTC 13:40 - 15:30!
NOTE: "El Escorial" is the large "Side Meeting Room". It is on the
ground floor. Immediately before, there is a lunch meeting in the room
(3GPP). Therefore the room will have to drain before we can start.
Therefore, we will start around at 14:40
NOTE: Michael Richardson will again be doing BRSKI hacking at the
Hackathon, so feel welcome to join to discuss or help (saturday /
sunday).
Number of participants on meetecho: 24 In the room: 16 (3:45 PM)
collaborative editing by WG members.
Presenter: Sheng Jiang (remote), Toerless Eckert (local)
Time: 10 minutes
RFC Editor Cluster C528
draft-ietf-anima-jws-voucher-16 - in RFC editor queue (misref)
Depending on draft-ietf-anima-rfc8366bis
Updates on WG documents without own slots
Update slides from authors later attached to chair slides
WIll keep it in AD queue until rfc8366 is released
Ongoing early review / document update since 122. Think document is
ready for AD to give it go-ahead.
Forwarded by Mahesh to IESG.
Before IETF122, authors planned to work on PoC implementation. Currently
no updates, but use-cased based PoC work still ongoing. Propose to park
document for three IETF.
Will Park it.
Newly adopted WG draft since IETF122:
draft-ietf-anima-registrar-considerations-00
draft-ietf-anima-masa-considerations-00
draft-ietf-anima-constrained-grasp-00
Note: Also requested (toerless) slot for draft in CORE-WG meeting to get
feedback from WG related to options of leveraging/requiring CoAP for
this (and potentially extending it)
Draft: draft-ietf-anima-constrained-voucher-28 (was -27 at IETF122)
Draft: draft-ietf-anima-constrained-join-proxy-17 (was -16 at IETF122)
Presenter: Esko Dijk (ED)
Time: 15 min
Mcr: Document still is marked WGLC, and maybe should be closed, and a
second WGLC should be started.
Reviews were done a few versions back, so maybe they would re-read.
coap+jpy scheme - thought we where pushed to that by some other
reviewer. Now we're being pushed back into another direction. so we will
change coaps+jpy:// => jpy://
ED: once you have a relay, you might wind up using it for other things
i.e. transport other/newer protocols in a backwards-compatible way.
(Generic = good) The "jpy" more generic scheme fits with that.
Next steps: check with the document shepherds (have one more look and
propose next steps).
Then check with all prior IETF out-of-WG/area reviewers, explaining the
updates and check if ok to proceed now.
Draft: draft-ietf-anima-brski-discovery-07
Presenter: Toerless Eckert
Time: 10 min
Esko: I'd like to do a DNS-SD review / check. (After IETF 123)
Michael: have a Rust implementation available.
Draft: draft-ietf-anima-rfc8366bis-13 (was -12 at IETF121)
Presenter: Michael Richardson
Time: 5 Min
Still looking for new Shepherd, else Sheng will become Shepherd.
Note: SID are manually added into the document because the YANG tools
available do not do this right today.
Esko: is this a problem that should be solved before progressing with
the draft, or not?
Michael: we do it manually - should be no problem for now. Only if
someone later extends the YANG model, which we may never have to do
because we have defined now an extension mechanism that can be used
instead.
Draft: draft-ietf-anima-constrained-grasp-01
Presenter: Longwei Zhu (remote)
Time: 10 Min
Toerless reminding presentation to CORE-WG tomorrow.
Esko/Toerless discussing re-use of CoAP with/without using CoAP features
as an ongong issue and unnecessarily adding overhead by replicating
features that could have been done at CoAP layer on the app-layer.
Draft: draft-ietf-anima-registrar-considerations-00
Draft: draft-ietf-anima-masa-considerations-00
Presenter: Michael Richardson
Time: 10 min
See also: draft-irtf-t2trg-taxonomy-manufacturer-anchors
Esko: option 1 looks ok ("BRSKI"). Can include ACP, non-ACP,
constrained, large/small etc as separate sections/considerations if
applicable.
Toerless: Was suggesting that these could be called just
"Considerations", not just "Operational Considerations" because that
for example could then also allow to include implementing
considerations.
Draft: draft-eckert-anima-acp-free-ani-00
Presenter: Toerless Eckert (local)
Time: 10 min
Did run out of time to present this @IETF122
Presenter: Toerless Eckert (local)
Time: 10 min
Slides: See
https://notes.ietf.org/notes-ietf-interim-2025-anima-01-anima
SJ: did not manage to get much followup from virtual-interim meeting
where we had a bunch of new work presented. Proponents are new to IETF,
so may not know what to do next, but Sheng is trying to help them with
next steps.
Discussion abcout how to allow academic students to best contribute to
ANIMA (or other IETF) work. Toerless suggesting that work on prototype
implementations of current/future ANIMA technology aspects allows most
easily to create a researsch contribution from it - by describing
protblem, solution through prototype code and results from
exercising/measuring the implemented work. This at least has been the
standard approach by researchers seen in other networking research
conferences, including but not limited to P4 forwarding plane research
work.
Sheng proposing to have more followup meetings wirh those research
proponents.
Bing: pretty exited to see use-cases from operators in interim.
Bing: maybe current ANIMA reference model is too complex for the new
contributors?
Lots of ongoing work in NMRG - using AI/agents for ops. Reference model
could be updated for this new work.
Toerless:
Sheng: (ONGOING 07/2025) Initiate IANA early review for BRSKI discovery
upon re-request from authors (next rev after IETF122)
Discuss signed GRASP for discovery etc..
