Implementing SSDP, the Simple Service Discovery Protocol
The cotton-ssdp crate encapsulates a client and server for the Simple Service Discovery Protocol (SSDP), a mechanism for discovering available resources (services) on local networks. A resource might be a streaming-media server, or a router, or a network printer, or anything else that someone might want to search for or enumerate on a network.
What is advertised, or discovered, is, for each resource, a unique identifier for that particular resource (Unique Service Name, USN), an identifier for the type of resource (Notification Type, NT), and the location of the resource in the form of a URL.
SSDP is mainly used by UPnP (Universal Plug-'n'-Play) systems, such as for media libraries and local streaming of music and video -- but the mechanism is quite generic, and could as easily be used for any type of device or resource that must be discoverable over a network, including in ad hoc settings which don't necessarily have expert network administrators close at hand.
