UPnP technology provides an effective foundation for networked devices that need simple, seamless interoperability for the home, office, and public domain. The UPnP device architecture enables connectivity of devices of all form factors. It provides networked devices with capabilities for automatic discovery, configuration, and control. It is a distributed networking architecture that leverages TCP/IP and other Internet technologies to enable flexible data communication between related devices under the command of UPnP control point entities. UPnP technology is independent of any particular operating system, programming language, or physical medium.-UPnP technology provides an effective foundation for networked devices that need simple, seamless interoperability for the home, office, and public domain.
