====SSDP====
[[Simple Service Discovery Protocol]] (SSDP) is a UPnP protocol, used in [[Windows XP]] and later. SSDP uses HTTP notification announcements that give a service-type [[URI]] and a Unique Service Name (USN). Service types are regulated by the Universal Plug and Play Steering Committee. SSDP is supported by many printer, NAS and appliance manufacturers such as Brother. It is supported by certain brands of network equipment, and in many [[SOHO network|SOHO]] firewall appliances, where host computers behind it may pierce holes for applications. It is also used in [[home theater PC]] systems to facilitate media exchange between host computers and the media center.
