Universal Plug and Play
Universal Plug and Play (UPnP) is an open industry standard that
uses Internet and Web protocols to enable devices such as PCs,
peripherals, intelligent appliances, and wireless devices to be
plugged into a network and automatically know about each other.
UPnP is an architecture for pervasive peer-to-peer network
connectivity of PCs and intelligent devices or appliances. UPnP
builds on Internet standards and technologies, such as TCP/IP, HTTP,
and XML, to enable LAN devices to automatically connect with one
another and work together.
With UPnP, when a user plugs a device into the network, the device
will configure itself, acquire a TCP/IP address, and use a discovery
protocol based on the Internet's Hypertext Transfer Protocol (HTTP)
