SAP (Session Announcement Protocol) Related Entries Web Links New/Updated Information Note: Many topics at this site are reduced versions of the text in "The Encyclopedia of Networking and Telecommunications." Search results will not be as extensive as a search of the book's CD-ROM. SAP is a protocol to announce Internet multicast conferencing sessions. A conference is announced by periodically multicasting a UDP announcement packet to a multicast address and port. Because SAP is designed for multicast, it is suitable for setting up conference calls, not one-on-one IP telephone calls. The IETF MMUSIC Working Group has developed SAP, which is defined in RFC 2974 (Session Announcement Protocol, October 2000). Also see "SDP (Session Description Protocol)" and "SIP (Session Initiation Protocol)." See "Multimedia" for a general description of multimedia conferencing. Also see "Voice over IP (VoIP)" for related information. Copyright (c) 2001 Tom Sheldon and Big Sur Multimedia.
