**Session Date/Time:** 26 Jun 2026 15:00 # [IOTDIR](../wg/iotdir.html) ## Summary The IOTDIR (IoT Directorate) held its pre-meeting for IETF 116. The session focused on reminding members about the document review process, providing status updates across various IoT-related Working Groups (WGs) and Research Groups (RGs) within the IETF and IRTF, and exploring future activities, particularly around AI agent interactions with IoT environments. --- ## Key Discussion Points ### IOTDIR Administration * **Ines Robles** reminded members of the importance of the review process. Even if a reviewer is not a domain expert, their unique perspective is valuable. * Reviewers are requested to accept or decline assignments as early as possible to allow timely reassignment and meet tight deadlines. ### Working Group Updates #### 1. Sixlow * **Carles Gomez** provided the update: * The WG will meet in Vienna. * Two documents are with the IESG for publication: * `draft-ietf-6low-pasa` (Path-Aware Semantic Addressing for LLNs): Currently being updated based on mailing list reviews. * `draft-ietf-6low-generic-address-assignment-option` (Generic Address Assignment Option (GAU) for 6LoWPAN ND): Authors are addressing feedback from a WG participant. * Three other WG documents in earlier stages: * `draft-ietf-6low-schc-154` (Transmission of SCHC compressed packets over IEEE 802.15.4 networks): Being updated to address minor issues with rollover modes. * `draft-ietf-6low-ipv6-over-owc` (Transmission of IPv6 packets over short-range optical wireless communications): Active update in progress. * `draft-ietf-6low-6overmstp` (Transmission of IPv6 over Multi-drop Serial Bus Token Passing networks): Recently adopted to obsolete RFC 8163. Key discussion point is whether to support SCHC as an optional mechanism for header compression. #### 2. ASDF * **Ari Keränen** provided the update: * The WG will meet in Vienna. * The primary focus is finalising `draft-ietf-asdf-sdf-nipsy` (Non-Internet Connected Devices Gateway Specification). * Work is ongoing on other drafts, including digital twins (`draft-ietf-asdf-digital-twin`) and mapping documents. #### 3. CBOR * **Carsten Bormann** provided the update: * `draft-ietf-cbor-diagnostic-notation` (Extended Diagnostic Notation) completed WG Last Call (WGLC). * Chairs are managing diverging opinions between two participants, but technically the specification is stable, and new implementations are emerging. #### 4. CORE * **Marco Tiloca** provided the update: * Two RFCs published since March: an informational RFC on IANA registration and a Proposed Standard on DNS over CoAP (RFC 9465). * Four documents are currently with the RFC Editor: * `draft-ietf-core-href` (Constrained Resource Identifiers) * `draft-ietf-core-cbor-c-ranges` (C-Ranges for point-holders in YANG CBOR) * Two group communication documents: transport (`draft-ietf-core-groupcomm-bis`) and security protocol (`draft-ietf-core-oscore-groupcomm`), clustered alongside related ACE WG documents. * Three documents completed WGLC: * `draft-ietf-core-coap-pubsub` (CoAP PubSub) — publication request expected soon. * `draft-ietf-core-coap-uri-path-abbrev` (CoAP URI path abbreviation) — new revision expected soon. * CORE CONF cluster: * Two documents completed their first WGLC; a second WGLC is planned. * Recently adopted `draft-ietf-core-yang-cbor-metadata` (representing metadata in YANG CBOR). * Other active works: clarifications on COAPs, multicast responses, and OSCORE security items. * Private SID translation for CORE CONF is being explored, with core work relevant to CORE and application-specific work likely routing to the SCHC WG. * The WG will meet for a two-hour session in Vienna, with virtual interims resuming in September. #### 5. IoT Ops * **Alexey Melnikov** and **Carsten Bormann** provided the update: * `draft-ietf-iotops-security-protocol-comparison` (Comparison of CoAP Security Protocols) was returned to the WG by the AD due to slow progress. * `draft-ietf-iotops-constrained-node-networks-terminology` (Terminology for Constrained Node Networks) has a PR addressing AD comments on MTUs and "secret shielding." * `draft-ietf-iotops-dns-guidelines` (IoT DNS Security and Privacy Guidelines) is active and expected to head to WGLC before Vienna. * `draft-ietf-iotops-yang-ownership-licensing` (YANG Ownership and Licensing Statement): Authors are preparing an update. * `draft-ietf-iotops-security-technologies` (Summary of Security Enabling Technologies for IoT Devices): Expired, but a new co-editor has been identified to revitalize the work. #### 6. Roll * **Ines Robles** provided the update: * The WG will not meet at IETF 116, but held an interim on 17 June. * `draft-ietf-roll-enrollment-priority` is currently in AD review. * Work continues on modifications and the NSA extension (`draft-ietf-roll-nsa-extension`). #### 7. SCHC * **Éric Vyncke** provided the update: * Holding interims every two weeks. * Key focus is on `draft-ietf-schc-architecture` (SCHC Architecture) and `draft-ietf-schc-coap` (SCHC over CoAP). #### 8. Suit and Teep * **Hannes Tschofenig** provided the update: * Many SUIT drafts are in IESG processing, with updates being made based on reviews. * TEEP progress is largely blocked waiting for the completion of the SUIT specifications in the IESG/RFC Editor queue. ### IRTF Research Group Updates #### Thing-to-Thing Research Group (T2TRG) * **Ari Keränen** provided the update: * Planning to meet in Vienna, focusing on "IETF IoT technologies in enabling AI agent interactions with IoT environments" (agentic IoT). * Seeking input and coordination with other IETF WGs working on related agentic IoT concepts. * Currently resolving a scheduling conflict with an AI agent BoF. * `draft-irtf-t2trg-ops-security-considerations` (Taxonomy of Operational Security Considerations for Manufacture Installed Keys and Trust Anchors) passed RG Last Call and is moving towards publication. --- ## Decisions and Action Items * **Action Item**: Members willing to review documents for the **Roll** WG (`draft-ietf-roll-enrollment-priority` and `draft-ietf-roll-nsa-extension`) should contact **Ines Robles**. * **Action Item**: IoT-related WGs and RGs to coordinate with **T2TRG** (via **Ari Keränen**) if they have ongoing work relevant to AI agents in IoT environments. --- ## Next Steps * IoT WGs will convene their respective sessions during IETF 116 in Vienna. * CORE interim meetings are scheduled to resume in September.
