Who is Invensys
•Automotive HVAC Controls
•Humidistat and motor speed controls
•Time Controls
•Thermostats
•Heat alarms
•Time Controls
OK, so?
● We will ship:– 50M smoke and co detectors– 40M to 50M appliance controls– 10M water heater controls– 5M thermostats– 1 – 2M refrigeration controls– ...
● We want to/need to/must interconnect these devices!
Goals
● Lots of Sensors – 100s; Many controls – 10s● No new wires; Reduce installation costs● Inexpensive - < $3 modules● Internet Connectivity● Open Standards
Open Standards
Standards are great – everyone should have one.
actually
“Efficiencies of proprietary solutions will be overcome by technology advances within one
development cycle”
What about Zigbee
● SNL● Stack is too:
– large – 64K– complex– expensive– untested– not IP compatible
Barriers to deployment● New Radio● New MAC – CSMS/CA plus GTS/Beaconing● New Network – AODV plus Cluster Tree● New API – Zigbee API plus ZODs● New Application
● CSMA/CA only MAC● AODV and IP● Sockets and SNMP
Risk Mitigation
To v6 or Not to v6
● 10M to 50M devices per year● Devices have IEEE 64bit addresses● Auto-configuration● No Nat
