IOTDIR

Summary

This pre-IETF meeting served as an informational update session for the IoT Directorate (IOTDIR) on the status of various IETF Working Groups and Research Task Forces relevant to the Internet of Things. Updates were provided on document progression, new work items, and upcoming meeting plans, particularly in preparation for the IETF 117 meeting in Vancouver.

Key Discussion Points

Meeting Logistics: The meeting was scheduled last minute due to summer vacation availability, resulting in potentially smaller attendance. Attendees were encouraged to add their names to the attendance list.
IOTDIR Reviews: A reminder was issued for IOTDIR reviewers to provide comments to the best of their knowledge when assigned, emphasizing that their expertise within the directorate is valued.
IETF Working Group Updates:
- 6LO: Will meet in Vancouver. Current documents include IPv6 ND Multicast Address Listener Registration (RFC editor queue), Path-Aware Semantic Addressing (latest version produced after early review), Transmission of SCHC Compressed Packages over 15.4 (new version planned to align with SCHC architecture draft), IPv6 ND Prefix Registration (early reviews received), and the recently adopted Transmission of IPv6 Packages over Short Range Optical Wireless Communications (plan to add optional SCHC header compression support).
- ANIMA: No update provided as chairs were not present.
- ASDF: Recently rechartered with new agenda items and milestones focusing on extending the ASDF specification and integrating NIPY (Non-IP Gateway) work.
- CBOR: Has several documents in the pipeline, including one that completed its second IETF last call and is expected to publish as an RFC soon. The working group is also exploring applications like concise DNS data transmission.
- CoRE: Published RFC 9423 (IANA registry for Target Attributes). Two documents are with the RFC editor (one in AUTH48, one in first edit step). Other working group documents are at various stages, including waiting for shepherd write-ups or reviewer resolutions. A second working group last call is expected for a CoRC-comp cluster document and the href document. Recent work includes CoRC documents, href, DNS over CoAP (marching towards WGLC), OSCORE security updates, and CoAP specification corrections/clarifications. Discussions on CoAP over the Bundle Protocol have also occurred. The WG plans regular interims and will meet for a 2-hour session in Vancouver.
- IALO: No update provided as chairs were not present.
- DETNET: Reported significant progress with several RFCs published this year.
  - RFC 9566 (Informational) details service protection (replication, elimination, ordering) over the IP data plane using MPLS over UDP/IP encapsulation.
  - RFC 9551 provides specifics for the packet ordering function.
  - OAM framework published; RFC 9546 provides MPLS data plane details. IP OAM and DETNET Yang are with the RFC editor.
  - ROW Technologies document is awaiting final IETF review and publication.
  - The Controller Plane Framework is nearing a working group last call after author updates.
  - The ROW Architecture document, still under refinement for consistency, may undergo another working group last call due to substantial updates.
  - A new document, "Data Plane Taxonomy," was adopted to facilitate evaluation of DETNET queuing proposals against scaling requirements, with discussions expected at the upcoming IETF.
- IOTOPS: No update provided as chairs were not present.
- LAKE: No update provided as chairs were not present.
- RATS: No update provided as chairs were not present.
- RUSH: Will not meet in Vancouver but plans a September interim. AUTH-R and AUTH-PROJECTION are in the ISG and ATD working group last call, with closure expected soon pending GitHub issue resolution and write-up updates. Enrollment Priority is next for working group last call. Work in progress includes MOEX ND extensions and RATS capabilities.
- SCHC: Holds bi-weekly interims. Main contribution has been updating the SCHC architecture draft (currently 02), which impacts other documents like the 6LO draft on SCHC over 15.4. Other topics include a draft on Zero Energy devices (considering a broader scope for low-energy and disruption scenarios), SCHC for IPv6, and developing a Forward Error Correction (FEC) mechanism for SCHC fragmentation.
- SCIM, SKIT, SWEET, TIPP: No updates provided as chairs were not present.
Research Task Force (RTF) Updates:
- COIN: The use case draft has moved to the RFC editor. There has been limited list activity, and updates for goals and milestones are pending. The group will not meet in Vancouver.
- T2TRG: Held a face-to-face meeting in Paris collocated with an IoT security hackathon, focusing on IoT security implementation, operation, and system aspects. A follow-up interim addressed information data and interaction modeling (Core/CoRN, Yang, CBOR). The group plans another interim soon but will not meet face-to-face in Vancouver. They will meet in Dublin and likely hold interims before then.
New Planned Activities/Other SDOs: No new activities or SDO updates were presented.

Decisions and Action Items

Attendees were requested to add their names to the attendance list.
IOTDIR reviewers are reminded to provide comments to assigned documents.
The meeting minutes will be posted to GitHub, and the video recording will be made available.

Next Steps

Several working groups (6LO, CoRE, DETNET) will hold sessions at IETF 117 in Vancouver.
Interim meetings are planned for RUSH (September), SCHC (bi-weekly), T2TRG (soon, and before Dublin), and CoRE (regularly alternating with design team meetings).
Working groups will continue progressing their documents through various stages (WGLC, RFC editor queue, updates for reviews).
