Re: [6tisch] Shipping minimal

[Tom Phinney]

Hi all, For me, resolution of point 2) depends on how long we expect "minimal" to be of use. In the short term, reference to 802.15.4e makes sense. However, if "minimal" is expected to be of use for more than a year or two, then it needs to be written in a way that tracks the most recently published IEEE 802.15.4 standard, as that is the one for which chip vendors will invest. In the short term, many available chips will support 802.15.4-2011 and 802.15.4e-2012, but in the future that support, for low-cost low-power high-capability SoC IoT devices, will track the most-recent version of IEEE 802.15.4. Industrial IoT is not a large enough sub-market to drive variance from the greater IoT market. Thus it is foolish (in my opinion) to insist on adherence to what the dominant market will consider an obsolete spec. -Tom ===== On 2015.05.01 08:05, Qin Wang wrote: Hi Pascal, After the discussion in the thread "Removing the "e" in the charter", do you still ask agreement about solution on the second point?  Personally, I prefer the text suggested by Pat, because it can decouple 6TiSCH from IEEE802.15.4 MAC. But, if the minimal draft is not final standard, I will agree the current solution for point 2.

So the proposal on the table is to add a well-known key as a default that can be modified at commissioning time. For 2) the spec makes explicit references deep into 802.15.4e so the proposal on the table is to maintain the reference to 802.15.4e as it stands now.   We are now calling for consensus on these 2 points. If you object please let us know and we’ll talk. We’ll conclude this call next Friday.   Cheers,   Pascal _______________________________________________ 6tisch mailing list 6tisch@ietf.org https://www.ietf.org/mailman/listinfo/6tisch _______________________________________________ 6tisch mailing list 6tisch@ietf.org https://www.ietf.org/mailman/listinfo/6tisch _______________________________________________ 6tisch mailing list 6tisch@ietf.org https://www.ietf.org/mailman/listinfo/6tisch
