Hi JP,

thanks, I agree and looking forward for new draft, but I think defining LLN is important so other WGs in IETF understand what is LLNs, I already asked the question to one WG and many have different definiotions. While the future internet will see a big grow/use in LLNs, it will be useful to define LLNs and in the end RPL is routing over LLNs.

Another point, which I think very important, in the meeting one input comment was surprised that ROLL WG had a presentation with using devices scenario of 1 W transmission power. Which still means some don't define "Low Power" in the same way, I will write my opinion on this in a separate thread, however, I suggest to define *Low Power* in the ROLL terminology draft, because LowPower is first/one important character of LLN and Lossy is the other.

See also the comment about the duty cycle of course.

Thanks.

JP.

A new version of the document will be posted, thanks for the comments! Just note that some of these terms are not
related to RPL but to LLNs in general though.
Thanks.

JP.
