SSDP (Simple Service Discovery Protocol)

SSDP (Simple Service Discovery Protocol) is a network protocol that allows devices on the same local network to discover and communicate with each other. It is commonly used in systems like UPnP (Universal Plug and Play) to automatically find devices such as printers, media servers, or smart home gadgets without manual configuration. When a device joins the network, it sends out a message announcing its presence, and other devices respond if they can interact with it. This seamless discovery process simplifies setting up and managing networked devices, making the technology user-friendly and dynamic.
