Reminder about IoT directorate reviews

AK: Sometimes we get answer to review requests from directorate members
that they "are not experts on the topic". You don't need to be expert,
or often even particularly well informed, of the topic of the draft, but
provide general review with focus on IoT-related topics. Chairs usually
try to assign reviews based on who we think would know the area best,
but sometimes such persons are already authors / active participants or
we don't find a good match and will do best-effort assignments.

Overview of the IETF/IRTF IoT groups

6TiSCH (Thomas Watteyne / Pascal Thubert)

6TiSCH is closed

6lo (Carles Gomez / Shwetha Bhandari)

ACE (Loganaden Velvindron / Tim Hollebeek)

ANIMA (Sheng Jiang / Toerless Eckert)

ANIMA will meet in Brisbane for a 1 hour slot, Monday 17:30 - 18:80

ANIMA has continued to work through weekly side meetings and githut
issue tracking (github.com/anima-wg) on most of its active WG drafts and
closed significant number of issues. Due to logical and author
dependencies, these have ended up becoming a cluster.

Adopted since IETF118 (not yet posted)

Passed WGLC sent to AD (some delay due to AD Change at IETF119 (from Rob
Wilton)

TBD waiting for discuss with authors @ IETF119:

Limited local attendance in Brisbane, hence chairs will ask WG if a
formal interim e.g.: end of April wouldmake sense (if remote attendance
due to TZ is also not going to work well.

Example core open issue is whether to keep YANG as data modelling for
the voucher (RFC8366) because there is still no tooling to automatically
convert YANG into the required JSON or CBOR code. BUt going away from
YANG would require to rewrite entire rfc836bis to be spec'ed into CDDL
(which supports JSON and CBOR).

ASDF (Michael Richardson / Niklas Widell)

Will not meet in Brisbane (except on the hallways)

ASDF is in the process of shipping draft-ietf-asdf-sdf-18 to the
IESG.
Rechartering upcoming, with an interim focused on that scheduled
for April.

with the hackathon on lightweight IoT security hosted by Inria.
Registration is open!

Documents:

    • "Amplification Attacks Using CoAP"
    • "A Taxonomy of operational security considerations for
      manufacturer installed keys and Trust Anchors"
    • "Guidance on RESTful Design for IoT Systems"

New/planned IETF/IRTF IoT activities

AK: BoFs? side meetings?

TE: Thursday side meeting on "Enterprise Network" -- all active

From low end to active devices in enteprises and campuses. Comparing
their operations challenges to IoT usage. Link?

CA: not SDO but research thing on next gen networks and security.
Bringing IETF experience to avoid re-inventing things. So far not much
online, best we have right now is COST website
