Universal Plug & Play

The Universal Plug and Play (UPnP) component enables dynamic networking of intelligent appliances, wireless devices, and PCs. The UPnP Application Programming Interface (API) consists of a set of Component Object Model (COM) interfaces used to find and control UPnP devices.

The Universal Plug and Play API enables developers to write applications that search for and control UPnP devices.

All applications that use UPnP typically perform the following tasks:

  • Find available UPnP devices on the network.
  • Determine which of these devices are of interest.
  • Issue control requests to the devices of interest and receive events generated by the devices.
