Re: [Iot-directorate] Question on IETF IOT-devices scope

Carsten, *:

Imho, no good deed goes unpunished: Maybe because of rfc7228 there is a
little bit of the mis-perception in the IETF that Io(T)hings are primarily things
with such memory/bandwidth/power constraints. Of course, a lot of
low-power networking work the IETF will have overall contributed to this
biased thinking we may have.

I for once think that (T)hings like cars as a device itself constituted
from maybe multiple networks with sub(T)hings will evolve to be a very
nice counter-example: As an electric car its not really power constrained
(definition: if you can waste highly toxic battery stored energy to warm
some passenger buttock, you are not a power constrained device ? ;-). With
maybe even in excess of Gigabits worth of streaming telemetry/video being 
rocessed when autonomous, its also not bandwidth constrained. Arguably not
 in the sense of rfc7228 compute constrained (definition: more compute power
than a current cell-phone is not compute constrained ? ;-).

But such examples and fun with them aside: I think one important "constraint"
 that we have not formalized, but which might be a better/broader classifier for
'non-IT' (T)hings is the absence of a personal caretaker/user for the
device and/or typical user-interface elements through which such a caretaker
can normally or at last in key ops scenarios manage the device: keyboard, mouse,
screen, or even rs232/usb console. Maybe there is some nice new
terminology/classification to be written to amend rfc7228. "Interfacing constrained
devices".

Cheers
