Re: [Roll] ** Resending ** Re: Adoption draft-martocci-roll-building-routing-reqs-01.txt as a new ROLL WG document

Dear Jerry,

The building draft was an interesting read and certainly warrants being a
stand-alone ROLL WG document. I felt however that the building and home
drafts have some similarities. To this end, would you please be so kind and
summarize in a few words the key differences between both approaches, mainly
from a routing perspective? Thanks. (For example, focus of the urban draft
is on scalability; focus of the industrial draft is on reliable and quick
reporting; focus of the home draft is, so I believe, on heterogeneity and
also quick response.)

A small side note on your assumption of 1000+ nodes in the network,
something we also struggle(d) with in the urban draft. Watteyne et al have
done some studies with real-world hardware figures assuming a 1000 node
network and figured out that - no matter how hard you try - you can not make
nodes report more frequently than every 8 seconds. This is mainly because
the nodes close to the sink run out of buffer pretty quickly. I think this
will have an impact on your mentioned applications because you either have
to perform some heavy aggregation (which has not been mentioned, I think) or
heavy prioritization (which is central to your draft but only in the context
of time critical alarms).

Kind regards,
Mischa.

As you know building automation is part of our charter. Could you please let
us know what you think about this ID (in favor or opposed)?

Thanks.

JP.
