Shepherd writeup

draft-ietf-anima-jws-voucher-16 - RFC Editor Queue Missref

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 |

And Esko is normally loud while Toerless is very quiet

Toerless is/was quite a bit away from the mic

I'm not sure the chairs read the chat, maybe somebody should sneak up to them and tell them

Better now?

Get some tape and stick the mic to Toerless' face... No, it's OK

This time he was nearly eating it :p

@meetecho the mic1 cam has gone blurry?

@Esko Dijk yes, sorry about that: just fixed

Wouldn't we use YANG identities for these strings?

Agree, we need 'identities' for that.

Maybe only standardize the CoAP variant?

@Meetcho, the presenter screen in Boromphimarn 4 does not seem to be working.

@Mahesh Jethanandani you mean the confidence monitor?

"confidence monitor" -- love it.

It's what you read from!

The monitor that the presenter uses to see what is being presented.

I did not know it was called "confidence monitor" \:grinning:

Ack, I just notified the AV team

Thanks

Chair Wrap-off

Todo

Sheng: Initiate IANA early review for BRSKI discovery upon re-request
from authors (next rev after IETF122)
Check with WG for next steps for BRSKI considerations - merge, adopt -
do we need interim to present/discuss ?

Discuss signed GRASP for discovery etc..
