Simple Service Discovery Protocol
- Simple Service Discovery Protocol
Simple Service Discovery Protocol (SSDP) is an expired IETF Internet draft by Microsoft and Hewlett-Packard. SSDP is the basis of the discovery protocol of Universal plug-and-play.
SSDP provides a mechanism which network clients can use to discover network services. Clients can use SSDP with little or no static configuration.
SSDP uses UDP unicast and multicast packets to advertise their services. The multicast address is 239.255.255.250 in IPv4. SSDP over IPv6 uses the following multicast addresses, depending on scope:
* Node-local: [FF01::C]
* Link-local: [FF02::C]
* Site-local: [FF05::C]
* Organization-local: [FF08::C]
* Global: [FF0E::C]
SSDP uses port 1900.
