Event Control: To avoid always having to actively query the status of services and other devices, UPnP devices use subscribed event messages by means of GENA (General Event Notification Architecture).Control: Cross-device communication takes place via the SOAP protocol, which is used to send messages to the device URLs to enable remote control.Description: The control point retrieves device descriptions via the HTTP protocol as an XML file containing details of manufacturer, serial number, driver information, and presentation, control, and event URLs.Discovery: The UPnP device uses the SSDP (Simple Service Discovery Protocol) to identify itself to other devices and control points in the network and is localized via UDP (User Datagram Protocol).

Addressing: In an IP network, network-enabled devices usually receive their IP address via the router and can be found and used in the UPnP network.

You no longer need to actively connect to devices thanks to UPnP, as they offer their services directly and grant access to files. The control software is either pre-installed in the network device or downloaded afterwards. The activated UPnP standard makes it possible to automatically identify network-compatible devices with their own IP address via control software and to access them from other devices.
