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 1 hour session, chaired by Sheng Jiang and Toerless Eckert, Wedneday, Session III, "Boromphimarn 4", 15:30 - 16:30 Meeting Time UTC 8:30 - 9:30 UTC! *NOTE: Michael Richardson will again be doing BRSKI hacking at the Hackathon, so feel welcome to join to discuss or hel (saturday / sunday).* Number of participants on meetecho: 23 In the room: 8 Note taker: INSERT YOUR NAME HERE, else collaborative editing by WG members. # Agenda / Notes ## 00 Chair slides Presenter: Sheng Jiang (local), Toerless Eckert (local) Time: 10 minutes Includes updates on WG documents without own slots New RFCs since IETF121: RFC9733 - BRSKI with Alternative Enrollment (BRSKI-AE) (was -13 at IETf121) draft-ietf-anima-brski-prm-18 (was -15 at IETF121) Update slides from authors later attached to chair slides On IESG Telechat in April draft-ietf-anima-brski-cloud-14 (was -11 at IETF121) WGLC after IETF121 passed, AD questions -13) answered via (-14), waiting for AD go-ahead draft-ietf-anima-grasp-distribution-12 athuros are working on prototype implementation (have open-source plan) & refining the use case text draft-ietf-anima-brski-cloud-14 (was -12 at IETF121) waiting for Shepherd writeup draft-ietf-anima-jws-voucher-16 - RFC Editor Queue Missref Draft: draft-richardson-anima-registrar-considerations Draft: draft-richardson-anima-masa-considerations See presentations from IETF107, 108, 116 Some work also ended up in draft-irtf-t2trg-taxonomy-manufacturer-anchors Discuss next step towards adoption - pls. review, interim ### BRSKI-PRM (slides included for reference, not presented) Draft: draft-ietf-anima-brski-prm-18 (was -15 at IETF121) ## WG draft slots ### 01 Constrained BRSKI Draft: draft-ietf-anima-constrained-voucher-27 (was -12 at IETF121) Draft: draft-ietf-anima-constrained-join-proxy-16 (was -15 at IETF121) Presenter: Esko Dijk Time: 10 min Michael Richardson: Problem of discovering invalid registrar may be overcome with trustworthy discovery mechanism, such as signed GRASP messages. Mcr: IANA table update request looks ok. (count a review) ### 02 RFC8366bis Draft: draft-ietf-anima-rfc8366bis-13 (was -12 at IETF121) Presenter: Michael Richardson Time: 5 Min TBD Michael: Lamps seems to have a new dependency against rfc8366(bis) which may still be resolved by appropriate text in the bis. Mean open topic of discussion (list) - what is the mechanism to extend vouchers with (proprietary) data without havinto write new RFCs because of a new YANG model every time... Mcr: wants to get onto NetMod agenda to get review, will also try to then go to YANG doctors. Mahesh: There is Kent as a co-author, ask him directly instead of going to NetMod. Or then ask chairs for YANG doctors review.... Carsten: Yang has identities, which means there are strings type/values.. (mcr understood it...) ## New Work *Order right now is just order of request arrival, and time is desired time be requester. We will re-shuffle and cut based on interest/discuss on the mailing list until the meeting.* ### 03 Lightweight GRASP proposal Draft: draft-zhu-anima-lightweight-grasp-02 (was -01 at IETF121) Presenter: Sheng Jiang, Longwei Zhu (local) Time: 10 min Carsten: Why should there be two ways of doing this ? Toerless: Would be important to provide good justification: 1. Propose change of name to "constrained-GRASP" given how all other CoAP work is called "constrained" in ANIMA 2. Enterprise networks where GRASP is used for communications between constrained IoT devices that do not have TCP stack but use CoAP instead. GRASP used for direct communications as well as per-hop constrained GRASP-proxy (daemon) 3. Not sure about need for pure UDP, but not CoAP based version. Or vice versa - would like to hear from CoAP folks. Sheng: does not agree to specify only CoAP or UDP, both may be used/preferred in different networks. Bing: very useful work. Also necessary. Supports adoption. Tends a bit to CoAP. Maybe better for implementers. ### 06 Mobility Management and Capability Negotiation Draft: draft-yan-anima-mmcn Presenter: Tianji Jiang (local) (From Zhiwei Yan <yzw_iplab@163.com> ) Time: 7 min ## Chat Log | author | text | time | | --- | --- | --- | | Carsten Bormann | <p>And Esko is normally loud while Toerless is <em>very</em> quiet</p> | 2025-03-19T08:42:19Z | | Holger Keller | <p>Toerless is/was quite a bit away from the mic</p> | 2025-03-19T08:46:26Z | | Carsten Bormann | <p>I'm not sure the chairs read the chat, maybe somebody should sneak up to them and tell them</p> | 2025-03-19T08:47:03Z | | Holger Keller | <p>Better now?</p> | 2025-03-19T08:48:38Z | | Carsten Bormann | <p>Get some tape and stick the mic to Toerless' face...
