The
Session Announcement Protocol (SAP) is a
protocol for broadcasting
multicast session information. A SAP listening application can listen to the well-known SAP multicast address and construct a guide of all advertised multicast sessions. SAP was published by the
IETF as
[RFC 2974].
SAP typically uses SDP as the format of the session descriptions, and the multicast sessions typically use RTP.
SAP is also the name of a German software giant.
Their products are in the
ERP business sector.
