UPnP: Universal Plug and Play
Peer-to-Peer local network connectivity of
intelligent appliances, wireless devices and
PCs
Standard-based connectivity to ad-hoc or
unmanaged networks
Uses IP, TCP, UDP, HTTP, and XML

UPnP (2)
UPnP devices
Auto IP configuration
Convey their capabilities
Leave the network smoothly
UPnP control points
Learn about the presence and capabilities of
devices
Use those capabilities

Ametsa Control Point
Developped upon the Intel's UPnP
implementation
Learns about the state of the UPnP network
Available UPnP devices
State of their services represented by a (set of)
variable (e.g. Control variable for the On/Off
service of a lamp)
Sends actions to devices
Accessible via a shell and SOAP interfaces

UPnP-X2D/X10 Gateways
X2D, X10
Powerline and radio communication protocols
Frequently used to control home devices
Need for a gateway to the UPnP network
Implemented as an UPnP device giving access to
X2D/X10 physical devices (lamps, shutters,
heating)
