Big thanks to Erik! :-) Welcome, Tommy! :-) Big thanks to Samita for her contributions to the IoT Directorate. :-) # Reminder about IoT directorate reviews {#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 {#overview-of-the-ietfirtf-iot-groups} ## 6lo (Carles Gomez / Shwetha Bhandari) {#6lo-carles-gomez--shwetha-bhandari} * 6lo will meet in Shenzhen * 2 new RFCs: * RFC 9926: IPv6 Neighbor Discovery Prefix Registration * RFC 9927: Fixing the C-Flag in EARO * 5 WG documents: * Path-Aware Semantic Addressing (PASA) for Low power and Lossy Networks (draft-ietf-6lo-path-aware-semantic-addressing-13) * WGLC passed. Ready to progress, held it until publication can be requested for GAAO * Generic Address Assignment Option for 6LoWPAN ND (draft-ietf-6lo-nd-gaao-09) * WGLC passed. Publication to be requested once a pending discussion is completed. * Transmission of SCHC-compressed packets over IEEE 802.15.4 networks (draft-ietf-6lo-schc-15dot4-12) * Been updated to address a review * Aligned with SCHC architecture terminology * Transmission of IPv6 Packets over Short-Range Optical Wireless Communications (draft-ietf-6lo-owc-05, will be -06) * Updates planned * Transmission of IPv6 over Multidrop Serial Bus/Token Passing (MS/TP) Networks (draft-lynn-6lo-6lobac-bis-01) * Intended to obsolete RFC 8163 (6lobac), some fixes and terminology update * New adopted document. ## ACE (Loganaden Velvindron / Tim Hollebeek) {#ace-loganaden-velvindron--tim-hollebeek} ## ANIMA (Sheng Jiang / Toerless Eckert) {#anima-sheng-jiang--toerless-eckert} ## ASDF (Michael Richardson / Lorenzo Corneo) {#asdf-michael-richardson--lorenzo-corneo} * Had approx monthly interims morning Europe time; difficult for US but only option to get US, Europe, and Asia * ASDF WG will not meet in Shezhen * Next WG interim meeting on March 11th to follow up two WGLC documents * The ASDF working group just published its first RFC 9880, which is the core specification of the semantic definition format, SDF for short * Non affordance draft (not the affordance, like button, but other stuff) * Non-Internet-Connected Physical Components (NIPC) draft progressing * Hackathong work planned for Vienna * The number of adopted working group documents increased a lot since the latest iotdir meeting. The working group has now 7 working group documents, 2 of which are in working group last call (ending early March) * Most of these documents are providing extensions to the core SDF specifications. For instance, SDF protocol mappings, instance information, non-affordances, and links * Another draft discusses the use of SDF and some of its extensions for the creation of digital twins * Finally, NIPC provides a standardized API for interacting with heterogeneous IoT devices from different ecosystems, e.g., BLE, Zigbee, using SDF for device modeling * 2 Internet Drafts related to SDF not yet adopted as working group documents, but they are in the working * One draft defines a compact notation for defining SDF documents, while the other draft provides SDF enablers for API translation using SDF ## CBOR (Barry Leiba / Christian Amsüss / Paul Hoffman) {#cbor-barry-leiba--christian-amsüss--paul-hoffman} ## CoRE (Jaime Jimenez / Marco Tiloca / Carsten Bormann) {#core-jaime-jimenez--marco-tiloca--carsten-bormann} * Published RFC 9876 "Updates to the IANA Registration Procedures for Constrained Application Protocol (CoAP) Content-Formats" * In RFC Editor Queue: RFC-EDITOR * draft-ietf-core-dns-over-coap --- "DNS over CoAP (DoC)" (Proposed Standard) * draft-ietf-core-coap-dtls-alpn --- "ALPN ID Specification for CoAP over DTLS" (Informational) * Approved for publication ➔ in RFC Editor Queue: EDIT * draft-ietf-core-href --- "Constrained Resource Identifiers" (Proposed Standard) * draft-ietf-core-groupcomm-bis --- "Group Communication for the Constrained Application Protocol (CoAP)" (Proposed Standard) * draft-ietf-core-oscore-groupcomm --- "Group Object Security for Constrained RESTful Environments (Group OSCORE)" (Proposed Standard) * draft-ietf-core-yang-sid-pen --- "YANG-CBOR: Allocating SID ranges for PEN holders" (Proposed Standard) * Among the WG documents: * 2 completed WGLC (-core-conditional-attributes, -core-coap-pubsub) * 2 expected to have a 2nd WGLC (-core-comi, -core-yang-library) * Recently adopted as a WG document: * draft-ietf-core-responses --- "CoAP: Non-traditional response form" * draft-amsuess-core-coap-over-gatt --- "CoAP over GATT (Bluetooth Low Energy Generic Attributes)" * Ongoing WG Adoption Call * draft-bormann-cbor-yang-metadata --- "Representing metadata annotations in YANG-CBOR" * Further ongoing activities * URI-Path abbreviation in CoAP, see draft-ietf-core-uri-path-abbrev * CoAP over Bundle Protocol (BP), see draft-ietf-core-coap-bp * CoAP Performance Measurement, see draft-ietf-core-coap-pm * More GitHub issues for "Constrained Application Protocol (CoAP): Corrections and Clarifications", draft-ietf-core-corr-clar * Key update for OSCORE (KUDOS), see draft-ietf-core-oscore-key-update * Protection/obfuscation of CoAP OSCORE option against tracking and message correlation, see draft-tiloca-core-oscore-piv-enc * CoRE will meet at IETF 125, in a 2-hour session on Friday, March 20 * After IETF 125, plan to resume interim meetings in April ## COSE (Ivaylo Petrov / Michael B. Jones) {#cose-ivaylo-petrov--michael-b-jones} ## DetNet (Lou Berger / János Farkas) {#detnet-lou-berger--jános-farkas} RFC Editor has almost completed the work on Reliable Available Wireless documents: RAW Technologies: RFC-to-be 9913 RAW Architecture: RFC-to-be 9912 The WG has started to work on DetNet queuing solutions by asopting some of the queueing solution proposals. ## IOTOPS (IOT Operations) (Alexey Melnikov, Henk Birkholz) {#iotops-iot-operations-alexey-melnikov-henk-birkholz} ## LAKE (Mališa Vučinić / Renzo Navas) {#lake-mališa-vučinić--renzo-navas} * LAKE did not have an interim meeting, will meet at IETF 125 Shenzhen (asked for 1h30 but we got 2h00) * Adopted documents (5 hits) some advancing since last IETF. * draft-ietf-lake-edhoc-psk waiting for formal analysis ( https://openwsn.atlassian.net/wiki/spaces/LAKE/pages/1932394542/Formal+Analysis+Process ) * draft-ietf-lake-edhoc-impl-cons, waiting for implementation experience * draft-ietf-lake-edhoc-grease is actually waiting for an implementation * Rechartering to include quantum-resilient solutions, almost there * Status: Start Chartering/Rechartering (Internal Steering Group/IAB Review) * https://datatracker.ietf.org/doc/charter-ietf-lake/ * Quantum-Resilient: drafts from 5 different groups of people (2 seem to be active) ## RATS (Kathleen Moriarty/ Ned Smith) {#rats-kathleen-moriarty-ned-smith} ## ROLL (Aris Koutsiamanis/ Ines Robles) {#roll-aris-koutsiamanis-ines-robles} * ROLL will not meet at IETF 125 * enrollment-priority was submitted to the IESG * dis-modifications merged with dis-modifications-use cases * nsa-extension in progress ## SCHC (Alexander Pelov / Pascal Thubert) {#schc-alexander-pelov--pascal-thubert} ## SCIM (Aaron Parecki / Nancy Cam-Winget) {#scim-aaron-parecki--nancy-cam-winget} ## SUIT (Akira Tsukamoto, Jacqueline McCall) {#suit-akira-tsukamoto-jacqueline-mccall} ## TEEP (Tiru Reddy / Nancy Cam-Winget) {#teep-tiru-reddy--nancy-cam-winget} # IRTF {#irtf} ## T2TRG (Ari Keränen / Carsten Bormann) {#t2trg-ari-keränen--carsten-bormann} Nothing specifically planned for IETF 125. Number of people on site limited. Operating in interims. Still working on setting up an interim about interaction between AI agents and IoT infrastructure; some reluctance about making WIP presentations. [draft-irtf-t2trg-taxonomy-manufacturer-anchors][1] completed RGLC, but didn't get any additional feedback; silence may be consensus here, but we'll need to extend the RGLC to get some. Work is also ongoing on enabling containerization/mobile code for IoT devices; there might be another interim for that as well. A number of informational documents are in author processing; [draft-irtf-t2trg-security-setup-iot-devices][2] is now close to RGLC and needs review. # New/planned IETF/IRTF IoT activities {#newplanned-ietfirtf-iot-activities} CB: opportunity for SUSTAIN RG and T2TRG people to meet around IETF 126. Will announce when we know more. Interaction with IoT device and controlling energy use -- good to get forward motion here. Organized by SUSTAIN RG. # Other SDOs {#other-sdos} MCR: IoTSF typically meeting in October. Some anniversary coming 2-4 day event coming. Will know around end of April. Will be happy to report on this. Also Device Identity forum making progress around representation around security icons, like certificates and quantum safety. Will probably have something to discuss in Vienna. Open for anyone to participate. # SLICES-RI project & SLICES-PI (Remous-Aris Koutsiamanis) {#slices-ri-project--slices-pi-remous-aris-koutsiamanis} RK: SLICES project with testbeds with homogeneous interfaces and different granularity (from bare metal to containers) for different experiments. Approved now for 2nd phase. Idea to do reproducable research for digital infra. For example, FIT project with outdoor/indoor real/isolated environments. Idea, depending on scenario, to be able to repeat scenarios. And high automation. Remous-Aris responsible for outreach to other orgs. If people have ideas on where and whom could talk to, e.g., help to do validation of ideas using this infra. People in the WGs who think this would be interesting avenue. EB: was part of FIT IoT lab some years back. Continue to use this to validate new proposals for IETF protocols. Can point to a few reports and papers. Could be good idea as blueprint. Also see https://www.iot-lab.info/ (in the process of being SLICEd ;) RK: idea is to not restrain just with French nodes. One in Madrid with satellite and LoRA for example. Have own micro satellite in orbit. AK: good idea to drop info to the directorate list and perhaps pointer to earlier similar use like Emmanuel pointed out RK: will have something more mature in summer; can then share details # AOB {#aob} (none; meeting closed) [1]: https://datatracker.ietf.org/doc/draft-irtf-t2trg-taxonomy-manufacturer-anchors [2]: https://datatracker.ietf.org/doc/draft-irtf-t2trg-security-setup-iot-devices
