Subject: FW: minutes from B2G call
|
I thought these comments were particularly pertinent to current
work in oBIX tc "If something is not worth doing, it`s not worth doing
well" - Peter Drucker
From: b2g_interop@nist.gov
[mailto:b2g_interop@nist.gov] On Behalf Of Shidan Gouran Hi, just wanted to add some opinions and comments since I
had to leave the call early today. With regards to 6LoWPAN and
6LoWAPP. 6LoWAPP and its associated protocol “CoAp” is essentially
ZigBee over IP. One constraint the 6LoWAPP WG is considering are networks with
500+ nodes and although there will be a significant sector where maybe 200
nodes will be the norm (PG&E' s architecture is a good example as one
application protocol for both the HAN and the NAN), its by no means a universal
model and, in fact, if we are considering just the HAN 6LoWPAN is more than
capable of handling HTTP, WS, SIP and XMPP. Many people, including myself,
think that the idea of CoGIIs as discussed by the 6LoWAPP group is very much
needed as an interface from CoAp to ATOM, WS, SIP, XMPP, etc.. With regards to the third
party access and privacy conversations, I really believe that an interface has
to be defined for full third party energy management and consumer facing
applications, whether its a service provider or facilities manager makes no
difference. OASIS is a great starting point for this and I personally think
that privacy should be something that should be opened to the service provider
or utility, but as long as it's initiated and controlled by the consumer at a
granular level, I don't think this would go against HIIPA. If this group can
take leadership to explore this, I think it would be great. Someone also
mentioned the privacy report from Ontario, a shameless plug here, the Ontario
Privacy Commissioners office and one of the authors of that report will be
present at our conference in Miami: http://http://smart-grid.tmcnet.com/conference/east-10/.
There are many people from this list I would love to have participate with us
so if your schedule is free and any of the panels interest you please send me a
note. With regards to ATOM, I
fully agree that it makes sense in the building. Just to add to this and in
case it wasn't already mentioned today, the various “real time web”
patterns like PubHubSub and two way Atom protocols like FeedSync would be
particularly good here. Another note, most of these real time web extensions
are modeling themselves after XMPP and SIP. I'm a member of the SIPForums Smart
Grid Special interest group, one thing we have identified is that openADR is a
very nice fit for SIP and for the third party energy management, here is a
white paper on it: http://www.sipforum.org/component/option,com_docman/task,cat_view/gid,95/Itemid,261/
My knowledge of BACNET, oBIX
and related WS protocols is very limited and I would like to understand what
areas, if any, SIP can be of benefit in this arena, hopefully like openADR oBIX
and the services are not necessarily tied to SOAP or anything else in
particular. Right now anything that involves ATOM and the “real time
web” or that can benefit from an event bus can be potentially a great fit
for real time communications protocols like XMPP and SIP (SIP being a service
discovery protocol as well). I'm looking forward to speaking to some of you to
gain some knowledge in this area. --- Shidan On Thu, Dec 10, 2009 at 4:46 PM, Holmberg, David <david.holmberg@nist.gov> wrote: B2G
all, Here
are my notes from the call today on the discussion of questions sent from
SBC Japan. Comments welcome. For
our Japanese colleagues—please review the notes and see if they answer
some of your questions, and please feel free to ask for clarification. There
are also questions in the notes for you as some use cases were not clear that
would influence the answers. Thank
you, David David
