SSDP
SSDP (Simple Service Discovery Protocol) is a network protocol used for advertising and discovering network services, primarily in UPnP (Universal Plug and Play) devices. It operates over UDP and allows devices to automatically find each other on a local network without manual configuration. SSDP is commonly used for media streaming, printer sharing, and IoT device communication.
Developers should learn SSDP when working with UPnP-based systems, IoT applications, or any project requiring automatic device discovery on local networks. It's essential for implementing features like media servers (e.g., DLNA), smart home devices, or network-attached storage that need to advertise services to clients without user intervention. Use cases include streaming audio/video between devices, automating device setup in home networks, and enabling plug-and-play functionality in embedded systems.
