Try to get implementation and get back then to WG. Toerless: maybe a revision with a [To be removed] explanation about this step. ## WG draft slots ### 01 Update on JWS-Voucher Draft: draft-ietf-anima-jws-voucher-12 (was -10 at IETF120) Presenter: Thomas Werner (Local) Time: 5 min If there is interest in interop testing, please notify authors. Mahesh: Some comments wherre posted - update hopefully posted, specifically from Jim Fenton, hopefully all addressed. Thomas: All remaining comments where addressed. Mahesh himself did not have comments, but supported those from expert review (Jim Fenton). One update did failed the deadline. Mahesh only needed the update: Please post -13 update now that datatracker ! Michael will do, so Mahesh can check. ### 02 Update on BRSKI-PRM Draft: draft-ietf-anima-brski-prm-15 (was -14 at IETF120) Presenter: Thomas Werner/Steffen Fries (local/remote) Time: 5 min ### 03 Update on cBRSKI - draft + code Draft: draft-ietf-anima-constrained-voucher-25 (was -24 at IETF119 - no update during IETF120) Presenter: Esko Dijk (local) Length of time requested: 10 min 2 independent validation of installing and running the simulation environment at the hackathon on the weekend (Michael, Stuart, Esko). Demo showed the simulator (OTNS2) running the cBRSKI code. Toerless reminding that chairs could request early IANA allocation for media type if desirable. Authors think its not necessary Thomas: voucher-cms+json in rfc8366bis consistent way ? Esko: Old approach. you can stick the cbor after the +, but cose is more specific. Outer encap mechanism should be after the +, e.g.: cms should have been after the + in RFC 8366, but it's not. Thomas: Also done wrong in JWS voucher ? Esko: No, outer encap (of JWS object) is json. So it's correct. ### 04 Update on BRSKI discovery Draft: draft-ietf-anima-brski-discovery-05 (was -04 at IETF120) Presenter: Toerless Eckert (local) Time: 10 min Toerless presents the slides. Esko: have to consider whether to support CoRE Resource Directory (RD). Which uses CoRE-LF, but is different. Esko: we can bring our CoRE-LF discovery questions to a CoRE Interim Meeting, held quite often. ## TIME PERMITTING - 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.* ### 05 Lightweight GRASP proposal Draft: draft-zhu-anima-lightweight-grasp-01 (was -00 at IETF120) Presenter: Sheng Jian (local/remote) Time: 10 min (5 min presentation + 5 min discussion) Sheng presents the slides. Reviews and comments are requested. Robin: Why not use QUIC instead of build our own reliability ? Sheng: Too heavy ? Toerless: how aboug CoAP ? Maybe try to compare own UDP encap vs. CoAP encap. Esko: CoAP is great when you do have the stack already on the device, but otherwise maybe not. Esko: TCP can be useful to avoid congestion, but maybe not good if your (wireless) nodes are moving around all the time. Toerless: GRASP flooding also an issue for constrained network. ### 06 NASR Presentation Draft: NA Presenter: Luigi Iannone Time: 5 min *Toerless pointed out similarities between fundamental technologies used by ACP and NASR (POT), and thought it would be good to make ANIMA WG aware of NASR work in that context.* Not presented - out of time. ### 07 Protocol Assisted Protocol (PASP) Draft: draft-li-rtgwg-protocol-assisted-protoco-06l Presenter: Zhenbin Li Time: 10 min (5 min presentation + 5 min discussion) We have the design of PASP proposed in the draft. It is said it may be based on ANIMA. Wish to learn possible comments through the presentation. ## Chair Wrap-off Time: (1 minutes) ## Todo Toerless: check that there is the link-local CORE-LF proxy discovery. Also check that Core-RD is mentioned. Some minute diference in Core-LF Resource Directory. Core-LF RD needs registrar message example.
