Stan Moyer Networked Appliances – 2  Definition  The Problem  Challenges/Issues  Assumptions  Requirements  Next Steps Outline

Stan Moyer Networked Appliances – 3 What is a Networked Appliance? (AKA: Internet Appliance or IP Appliance) Networked Appliance (NA): n. A dedicated function consumer device containing a networked processor. Examples: Lamps Coffee Makers Alarm Clocks Phones

Stan Moyer Networked Appliances – 4 How are NAs communicated with?  Directly; Appliance Controller  Indirectly;

Stan Moyer Networked Appliances – 5 Public Internet Something we can’t do today (securely)… Home domain Corporate Intranet Mobile network Any data network! Commands: “Turn off all lamps” “Turn off gas” “Enable house alarms” “Record ‘Frasier’ on NBC” Queries: “What’s the kitchen temperature?” “Are all the doors locked?” “Is there milk in the fridge?”

Stan Moyer Networked Appliances – 6 What else do we want?  I want my networked appliance services to “follow me” –Device portability –Location independence (service portability) Home Office Hotel Vacation Car Service Provider

Stan Moyer Networked Appliances – 7 Networking Appliances Today… A Multitude of Devices and Technologies… X.10 VESA home n/w Home P’n’P UPnP Jini HAVi …

Stan Moyer Networked Appliances – 8 RGW/NAT/ Firewall Issues accessing into the home… Home.simon.net (public) DNS Where’s Simon’s bedroom lamp? Appliance Controller (X.10) 1. Addressing & Numbering 2. Control Protocols/Interfaces B0 (X.10) B1 (X.10) (Private IP) tv.home.simon.net (Public IP) Proprietary Any one of a multitude of systems. X.10 What protocol Should I use to communicate with the Appliance?

Stan Moyer Networked Appliances – 9 Different Communication Modes  Control –“Turn on the outside light”  Queries –“What is the temperature in the house?”  Asynchronous Events –“Notify me when the security alarm goes off”  Media Streaming –“View the baby-sitter cam”  Discovery –“What device can meet requirement X?”

Stan Moyer Networked Appliances – 10 Assumptions  Local area network (connectivity, naming, addressing) is already configured –Manually –Automatically (a la zeroconf)  Wide area connectivity exists  Firewall and/or NAT may exist between wide area and local area

Stan Moyer Networked Appliances – 11 Requirements Need support for:  Wide area naming and addressing –Globally unique –Portable within and across service provider domains –Work through firewalls and/or NATs  Device mobility  Protocol transparency and independence  Security (and privacy)  Different communication modes

Stan Moyer Networked Appliances – 12 Next steps  Informal “bar BOF” tomorrow, Dec. 12, at 11:30am –RSVP ( ) Stan Moyer if interested in attending –Meet at message board outside terminal room  Official BOF at Minnesota IETF in March?   – to subscribe  Current drafts –draft-moyer-sip-appliances-framework-01.txt –draft-tsang-appliances-reqs-01.txt –draft-tsang-sip-appliances-do-00.txt –draft-khurana-dmp-appliances-00.txt

Stan Moyer Networked Appliances – 13 Is this what we really want? Another beer, please, HAL… I’m sorry, Dave. I can’t do that. The bathroom scale and the hall mirror are reporting disturbing flab anomalies SMART APPLIANCES
