Laurent to send a doodle on the ML to choose a time for a session on YANG
(last interims for copy/paste)
Alexander gives the usuual intro script, this is an aofficial IETF meeting BCPs apply (inc. IPR). No recording. Meetings minutes captured here.
Laurent suggests to talk about the Yang document. Minutes of last meeting approved
OAM draft not yet a WG document. Document to be reviewed and brought back to the WG's attention.
Yang draft, version 4 published. Need a work session with interested parties.
Olivier: Limited change; editorial clarification. Also an IID-related update. Support of the proposed IID derivation algo is a MUST, using it is a SHOULD. Fixing the hexa: the new value is confirmed; the current plan is to wait for AUTH 48 to inject the correction. Suggestion to send the fixed XML now to the RFC Editor before they start editing it.
Carles: using SCHC HC in 6LoWPAN space. Carles presents history (see slides) Carles: Add SCHC compression in addition to 6Lo HC
Might consider a SCHC HC dispatch. Use the page selector, use a whole page?
Carles: can go from 7 to 2 bytes Pascal: SCHC can compress also other layers, so the gain can potentially be more imporant. Pascal: SCHC is stateful - you need preparation. 6LoWPAN is stateless - you don't need any previous setup (any-to-any). So it's really a different usage: RFC 6282 is minimum preparation minimum win. SCHC is max preparaion, node specific etc... but max win as well. Carles: in terms of context, even in 6LoWPAN if you have global addresses, you still need some kind of contexts, or infrasturcture with ND to discover this common context. Carles: effect of the compression on battery lifetime, from theoretical point of view. Carsten: what's the use of using 6LP then SCHC? Laurent: An example would be for mesh networks to use 6LP to route the packets on the IP layer, and use SCHC for the compression of the upper layers Pascal: RFC8138 is what you want to cross the mesh (on route-over) Carsten: That may need a lot of thinking to get right Pascal: need use-cases Alexander: The work seems a good thing to pursue, need to clear up the targeted use-cases Alexander: the home WG would be 6LO? Carles: yes, 6LO Alexander: advance the work in LPWAN, make sure we agree that it's good enough, then ask for adoption in 6LO, and ensure WGLC in 6LO and LPWAN Eric: yes, agreed. Need to double-check on the 6LO charter of course. Working Group Last Call should be done in 6LO and LPWAN.
See slides; Laurent suggests to keep the existing IGNORE as is and create anew matching operator MATCH_LENGTH so that the rule indicates the length of teh variable length field.
