Re: [6tisch] Mirja Kühlewind's Discuss on draft-ietf-6tisch-architecture-24: (with DISCUSS and COMMENT)

["Pascal Thubert (pthubert)" <[e-mail]>]

Hello Mirja

Your time is appreciated, many thanks for considering this draft.

The 6TiSCH Architecture has been a WIZp throughout the lifespan of the WG. It may be seen as its main product, most of the needed components being requested from other WGs.

This may be unusual but that was the plan from the start: produce a rather generic iot stack out of IETF components, which when we started were full of gaps and overlaps.

5 years later we have open source implementations that went through multiple interop tests, all under the group’s monitoring.

So the Architecture is not there to tell us what to do next but rather how what we (many iot relater WGs) built and how it works together.

The decision to go for informational is not mine. But what’s the point to have normative References in an informational draft?

Again, many thanks.

Pascal
