Universal Plug and Play (UPnP) is a distributed, open networking architecture that enhances peer-to-peer network connectivity for personal computers, wireless devices, and other intelligent appliances. UPnP uses existing standard protocols, such as TCP/IP, Hypertext Transfer Protocol (HTTP), and Extensible Markup Language (XML) to seamlessly connect networked devices and to manage data transfer among connected devices.
Note For information about differences between the UPnP implementation available for Windows Mobile devices and that available for Windows Embedded CE devices, see UPnP in Windows Mobile Devices.
UPnP provides an architectural framework for creating self-configuring, self-describing devices and services. Networks managed by UPnP require no setup by users or network administrators because UPnP supports automatic discovery.
UPnP enables a device to dynamically join a network, obtain an IP address, and convey its capabilities on request. Control points can use the UPnP application programming interface (API) to learn about the presence and capabilities of devices that are registered on the network. A device can leave a network smoothly and automatically when it is no longer in use.
UPnP uses no device drivers. It is media-independent and can be used on any operating system (OS). UPnP offers programmatic control to applications. UPnP enables developers to write their own user interfaces for devices, forgoing the vendor-provided interface.
 Security
Note: |
|---|
| Because a UPnP service can potentially be remotely activated without authentication, it presents an area of vulnerability for a networked system. When UPnP services are deployed in a controlled environment, such as a home or business intranet where all the users are trusted, the risk of malicious attack is lessened. |
