Hello WIT Area,The CoRE WG focuses on application protocols that enable constrained nodes to participate, in particular the Constrained Application Protocol (CoAP). CoRE will meet on Tuesday, November 5, for a 2-hour session.
Procedurally, 1 document is with the RFC Editor (AUTH48), 2 wait for the Shepherd write-up, and 4 more have completed their WG Last Call.
CoAP is designed to enable group communication; the main work items that revamp the main document ("groupcomm-bis") and address secure communication ("oscore-groupcomm") have been updated according to recently received, additional reviews and should be completed soon. A related document specifying how proxies facilitate group communication is also progressing.
We have recently adopted draft-ietf-core-corr-clar as a standing WG document, which aims to collect corrections and clarifications about the use of CoAP in various CoAP-related RFCs. The intention is to converge on WG resolutions for filed errata, open issues, and reported experience.
WG items on the agenda for IETF 121 include the following topics: advancing the remaining documents of the CORECONF cluster (efficient YANG); Concise Resource Identifiers (CRIs) as compact equivalent of URIs; parameters for controlling the behavior of CoAP observations (RFC 7641); DNS over CoAP together with related, supporting documents; means to indicate transports available to use for CoAP; a CoAP-based architecture to achieve pub-sub communication; replacing RFC 7390 about group communication for CoAP (e.g., over IP multicast); proxies in scenarios that use group communication for CoAP; the protocol KUDOS for updating keying material to use with the security protocol OSCORE (RFC 8613).
Individual submissions on the agenda include the use of CoAP over the (DTN) Bundle Protocol (BP) and a stateless variant of OSCORE.
CoRE plans to have a one-off interim meeting on 2024-12-18, and then to resume its biweekly interim meetings on 2025-01-15 until IETF 122; one objective is to make steady progress on draft-ietf-core-corr-clar in each of the meetings.
