What is UPnP and how does it work?
UPnP, or Universal Plug and Play, is a set of networking protocols that allows devices to automatically discover and connect to each other on a network. It enables devices such as routers, printers, and smart home devices to communicate with each other and share resources without the need for manual configuration. UPnP works by allowing devices to advertise their presence and capabilities to other devices on the network, which can then use this information to establish connections and access shared resources.
The UPnP protocol is based on a set of standard protocols and APIs that allow devices to discover, describe, and control each other. When a device connects to a network, it sends out a discovery message to announce its presence and capabilities to other devices. Other devices on the network can then respond to this message and establish a connection to the device. UPnP also provides a set of APIs that allow devices to control each other and access shared resources, such as streaming media or printing documents. By automating the process of device discovery and connection, UPnP makes it easy to set up and use networked devices without requiring technical expertise.
