What are the technical elements of UPnP?
A. UPnP is broad in scope in that it targets home networks, proximity networks, and networks in small businesses and commercial buildings. It enables data communication between any two devices under the command of any control device on the network. UPnP is independent of any particular operating system, programming language, or physical medium. UPnP supports zero-configuration networking and automatic discovery, whereby a device can dynamically join a network, obtain an IP address, announce its name, convey its capabilities upon request, and learn about the presence and capabilities of other devices. DHCP and DNS servers are optional and will be used if available on the network. Furthermore, a device can leave a network smoothly and automatically without leaving any unwanted state behind. UPnP learns from the Internet’s success and heavily leverages its components, including IP, TCP, UDP, HTTP, and XML. UPnP involves a multi-vendor collaboration for establishing standard Device Control
