2.6.5 UPnP
Universal Plug and Play (UPnP) is a distributed, open networking standard that uses TCP/IP for
simple peer-to-peer network connectivity between devices. An UPnP device can dynamically join a
network, obtain an IP address, convey its capabilities and learn about other devices on the
network. In turn, a device can leave a network smoothly and automatically.
