Here is my summary of what we did on Tuesday. Fixes/additions welcome; details are in the draft minutes at http://etherpad.tools.ietf.org:9000/p/notes-ietf-95-core On Tuesday: * Andrew indicated that he plans to step down as a WG chair and that the ADs are looking for a replacement. * As periodically, the AD is changing; this time from a graybeard (Barry) to a blackbeard (Alexey). * The chairs apologize for the infrequently updated milestones; fixing them is up next. * draft-ietf-core-block–19 is in IESG Evaluation, telechat date is 2016–04–21. * heads-up for new individual drafts: draft-kivinen-802-15-ie and draft-bormann-6lo-coap-802-15-ie. * CoAP over TCP received extensive discussion. Results (all to be confirmed on the mailing list): * #396: We revert the decision in Yokohama and go with alternative L3. Procedurally, the pain of this reversal is balanced by the reduced pain of not having to convince OCF to change their specification. Technically, L3 is more open to evolving ideas about message sizes. In any case, there is no intent to modify or revoke section 4.6 of RFC 7252 at this time. * We will need to examine the various proposals to add signaling to the TCP connection (settings, ping/pong, release/abort). Signaling messages (7.xx) is one possible mechanism for doing that. * #387 (ALPN): We really need to make a decision here. * Websockets: For merging the websockets draft into the TCP/TLS WG document (with the websockets specific parts going to an appendix), the authors of both drafts will discuss the merge. * Multi-hop Security: Initial discussion of draft-hartke-core-e2e-security-reqs. * It is more well-defined what is being protected in a request-response that spans a proxy than with a pub-sub broker. * The current set of scenarios does not include the case that security services are being performed by the intermediary. Many such scenarios are conceivable; which ones have serious use cases? * Multicast (or, more generally, group communication) is not yet being considered. * Data Formats: WG to adopt SenML (to be confirmed on the mailing list). After a bit of Brownian motion, the WG is now happy with the way the data is formatted in -06 (base record with data, zero or more records with more data). The addition of links in the data is to be done by registering a senml label in core-links-json ("reversing the arrow of dependency"). Friday meeting upcoming. Grüße, Carsten
