I would say the modeling of size of an IoT endpoint is a floating target.
The text can be more elaborate on it
going to a classic endpoint like PhilipHue lamp (in the Realtime booth on
FOSDEM) I have modeled every lamp as individual JID. Some argue Philips
has sold 10M lamps
If philips provided XMPP-IoT as their API, that would lead to 10M JIDS on
their xmpp server.
Or should each gateway have a JID with the connected lamps behind? The API
from Philips is very gateway centric *gatewayID/lamp1...lampXX*
Or just one JID MasterBot(a)philipsHue.com that just acts as a messaging
proxy to any lamp and you set up your JID credentials on my.meethue.com
(being a concentrator)
<message from='myjid(a)domain.com/mobile'
to='MasterBot(a)philipsHue.com'>
<set xmlns='urn:xmpp:iot:control'>
<node nodeId='PhilipsHUEGatewayID'/>
<boolean name='Lamp1OnOff' value='True'/>
</set>
</message>
*Control should probably use
tokens http://www.xmpp.org/extensions/xep-0325.html#tokens
<http://www.xmpp.org/extensions/xep-0325.html#tokens> and the PhilipsHue
access keys generated when the push button is pressed on the gateway.*

I haven't yet made time to deeply review and post
at length about the IoT
XEPs. However, I've looked at them all briefly and I have a high-level
question about their focus and intent. Several of them mention use cases
involving millions of devices on an IoT network, and even millions of
devices behind a single JID acting as a concentrator. Do we truly think
this is a realistic scenario? Most of the use cases I hear about from
customers (not involving XMPP) as well as the real-world usage of XMPP I
know about (e.g., in demand-response systems) involve perhaps a few hundred
edge devices (sensors, actuators, and the like) at any given deployment
(e.g., at a factory, office complex, oil refinery, or construction site).
Personally I do not see a need for millions of endpoints behind a single
concentrator JID. I don't think I even see a need for millions of endpoints
on any single customer deployment - tens of thousands seems a lot more
plausible. Perhaps the authors were thinking about a single central server
at an XMPP-based IoT service provider handling that many endpoints for
multiple customers across all of their physical locations?
