The descriptive part of this document would be covered by/merged to the output of the LWIG. And the roadmap document, if exactly as implied by the name, is okay for 6lowpan. But I do expect you can output the guideline part (e.g., MTU section) to the LWIG document, and we surely will collaborate with each other on the topic. > > While it is possible there will be some overlap in the fringe areas between > the two, with a little bit of forethought that can be controlled. > And, yes, I'd expect LWIG to be a working group that we want to closely > collaborate with, both with respect to this guide and with respect to the > other 6LoWPAN documents. -- Best regards, Zhen _______________________________________________ 6lowpan mailing list [email protected] https://www.ietf.org/mailman/listinfo/6lowpan
