Reminder about IoT directorate reviews

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.

Remember to accept/decline the review request as soon as you can so we
know if we need to ask someone else to review.

Overview of the IETF/IRTF IoT groups

6lo (Carles Gomez / Shwetha Bhandari)

6lo will meet in Montreal.

6 WG documents.

2 WG documents in the RFC Editor Queue (both in EDIT state):

• IPv6 Neighbor Discovery Prefix Registration
  (draft-ietf-6lo-prefix-registration-18)

4 other WG documents in earlier stages:

• Path-Aware Semantic Addressing (PASA) for Low power and Lossy
  Networks (draft-ietf-6lo-path-aware-semantic-addressing-13)

  • WGLC done, Shepherd review and writeup uploaded, ready to
    progress, holding until GAAO reaches the same stage.

  • Dependency on the SCHC architecture draft

• Transmission of IPv6 Packets over Short-Range Optical Wireless
  Communications (draft-ietf-6lo-owc-05)

Individual drafts:

  (draft-choi-6lo-owc-security-03)

  • Authors would like to integrate this content into the main IPv6
    over OWC draft

CBOR (Barry Leiba / Christian Amsüss / Paul Hoffman)

Paul joined chairs team to help assess consensus situation in 3
slow-moving documents. WG focusing on those.

Regular interims, and will meet in person.

• Deterministic encoding: Consensus that work is needed, but adopted
  document far from consensus. Some push for changes to CBOR, but
  not clear yet.
• Diagnostic notation probably on a good path, but occasionally
  entangled in encoding topics.
• packed about in-place consumable elided repeated (or otherwise
  known) items. Authors consider it done, unclear concerns (mainly for
  lack of bandwidth competing with other topics).

CoRE (Jaime Jimenez / Marco Tiloca / Carsten Bormann)

• draft-ietf-core-cf-reg-update (in RFC Editor Queue: AUTH48)

  • RFC-to-be 9876 "Update to the IANA CoAP Content-Formats
    Registration Procedures"
