What is a Networked Appliance? (aka IPA)What is a Networked Appliance? (aka IPA)
A networked device with–Dedicated functionality, limited configurability, and
optimized UI–Ability to interact with the physical environment
through sensors & actuators–Limited (or restricted) general-purpose
computational power A.k.a. Internet Personal Appliances (IPAs),
networked appliances, Internet appliances, IP appliances, networked devices, …

SIP + Instant Messaging For IPAC…SIP + Instant Messaging For IPAC…WHY?WHY?
Leverage existing infrastructure. Leverage existing management and operations
systems. Leverage existing expertise/skills in SIP. THIS IS JUST ANOTHER VALUE-ADDED
APPLICATION USING SIP.

Why not…Why not…
SNMP Not real-time response, Client/server relationship

Connection orientedSMTP No event notification, No support for sessions/media
streaming, Not real-time responseA new protocol Do we need yet another protocol?
