[6tisch] Call for adoption of draft-richardson-6tisch-dtsecurity-secure-join as WG document

2016-11-22 Thread Pascal Thubert (pthubert)
Dear all : The sense of the room at the WG meeting at IETF 97 in Seoul was that draft-richardson-6tisch-dtsecurity-secure-join and draft-vucinic-6tisch-minimal-security could be combined as a staged join process, the former being optional in the case of a PSK, and that the two documents

2016-11-22 Thread Simon Duquennoy
Hi all, Reading the current draft draft-ietf-6tisch-6top-protocol-03, a few points were not clear to me: * Section 4.2.7: why do cells only have a recommended format? I guess it's up to the SF, but if so, this is worth stating explicitly. * Section 4.2.7: what happens when cells don't fit a

I agree witb Yatch: On Step 1, keep the original CLEAR command at boot time. Step 2 is OK for me: In fact, the only way SF0 would detect that the node is no longer available or that RPL has decided a parent change is that there will be no more effectively used cells towards that neighbour, so

Hi all, Here is my opinion: step 1: one suggestion to keep the original sentence explaining what to do in SF0 after the system booting-up or restart. That is, no change on draft-ietf-6tisch-6top-sf0-02#section-10. step 2: +1 Thanks! Yatch On 2016/11/22 8:16, Thomas Watteyne

Thanks Maria Rita for agreeing to add the term. Can I ask you to do the edit in the repo? About last call, while I agree with the definitions in there, we MAY want to remove some, or at least do a sanity check. Maria Rita, could I ask you to go through the list and make some recommendations?

I think that we need to remember that in some cases CCA is necessary for minimal, such as shared slots, but also when there are multiple instances of 6tisch being used by non-coordinated entities. Regardless, "In the TSCH mode, backoff is calculated in shared links, so the CSMA-CA

Xavi, sure, we can add CCA among the terms. Pascal, about the last call for the terminology draft, I believe we can go for it. Maybe we only need to check first if there are new terms coming from the 6P and SF0 drafts (but I doubt, because we checked already last time), or from the latest

That would be good. Also: as discussed at the IETF meeting, we also need to trigger last call for the terminology draft, which will cause minimal to be held for publication otherwise. Maria-Rita, do you think we are ready for that? Take care, Pascal From: 6tisch
