Editing Zero-configuration networking (section)

===UPnP===
[[UPnP]] has some protocol components with the purpose of service discovery.

====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.

====DLNA====
[[Digital Living Network Alliance]] (DLNA) is another suite of standards that uses UPnP for the discovery of networked devices. DLNA has a long list of prominent manufacturers producing devices such as TVs, NAS devices and so forth that support it. DLNA is supported by all major operating systems. DLNA service discovery is layered on top of SSDP.

====Efforts toward an IETF standard protocol====
SLP is supported by [[Hewlett-Packard]]'s network [[Computer printer|printer]]s, [[Novell]], and [[Sun Microsystems]]. SLP is described in {{IETF RFC|2608}} and {{IETF RFC|3224}} and implementations are available for both [[Solaris (operating system)|Solaris]] and [[Linux]].
