UPnP logo as promoted by the UPnP Forum (2001–2016) and Open Connectivity Foundation (2016–present). Universal Plug and Play (UPnP) is a set of networking protocols on the Internet Protocol (IP) that permits networked devices, such as personal computers, printers, Internet gateways, Wi-Fi access points and mobile devices, to seamlessly discover each other's presence on the network and ...
Diagram of the UPnP ' s discovery phase. Internet Gateway Device (UPnP IGD) Control Protocol is a protocol based on UPnP for mapping ports in network address translation (NAT) setups, supported by some NAT-enabled routers.
A UPnP client, also called a control point, functions as a digital audio/video remote control. Control points automatically detect UPnP servers on the network to browse content directories and request the transfer or streaming of media. A UPnP media renderer performs the actual audio or video rendering.

This article lists protocols, categorized by the nearest layer in the Open Systems Interconnection model.This list is not exclusive to only the OSI protocol family.Many of these protocols are originally based on the Internet Protocol Suite (TCP/IP) and other models and they often do not fit neatly into OSI layers.
LAN systems tended to provide more automation of these tasks so that new equipment could be added to a LAN with a minimum of operator and administrator intervention. An early example of a zero-configuration LAN system is AppleTalk, a protocol introduced by Apple Inc. for the early Macintosh computers in the 1980s. Macs, as well as other devices ...
Various NAT traversal techniques have been developed: NAT Port Mapping Protocol (NAT-PMP) is a protocol introduced by Apple as an alternative to IGDP. Port Control Protocol (PCP) is a successor of NAT-PMP. UPnP Internet Gateway Device Protocol (UPnP IGD) is supported by many small NAT gateways in home or small office settings. It allows a ...
Multiple registrars should have the ability to connect to the AP. UPnP is intended to apply only to a wired medium, while actually it applies to any interface to which an IP connection can be set up. Thus, having manually set up a wireless connection, the UPnP can be used over it in the same manner as with the wired connection.
