Event notificationДЄ control point may register itself as a service to get notifications for any device state changes. These control messages are in XML format using the Simple Object Access ProtocolВ ( SOAP). In order to interact with discovered device, the control point sends suitable messages for invoking actions on services. Each UPnP service has an URL for control and events listening. The device description XML gives an important information about the device such as a list of supported services.

The UPnP Device Description is in XMLВ ( eXtensible Markup Language), which includes information like: vendor, model name, serial number, URL, etc. The control point requests the device description via the location URL. Once a control point finds a device, it must retrieve its capabilities and services. The discovery messages contain essential specifics about the device or one of its services: its type, identifier, and a pointer (network location) to more detailed information. A control point can actively search for devices of interest or listen passively to Discovery ServiceВ messages. The device advertise its services to the network using SSDP alive messages. The discovery protocol or the Simple Service Discovery ProtocolВ ( SSDP). DiscoveryДЄfter device addressing, the next step into UPnP networking is device discovery. This can be achieved using a lookup into Dynamic Host Configuration ProtocolВ ( DHCP) server or assign an IP address using AutoIP. To be part of the network, the device must have a unique IP address assigned. This point is related to device IP address assignment.

The UPnP specification consists mainly of six phases: Addressing The UPnP is based on a client-server concept, where UPnP control points (clients) search for UPnP servers (devices) that provide different standard services. It involves a lot of standards and technologies such as: The UPnPВ architecture allows device-to-device networking of electronic devices such as mobile phones, personal computers, Smart TVs (Connected TV)В and other type of home network appliance. The Universal Plug and PlayВ ( UPnP) concept is a plug-and-play extension that is a technology for dynamically connecting devices to each other without the need for physical device configuration or user intervention.
