SIP
It is the industry standard protocol described in http://www.ietf.org/rfc/rfc3261.txt - IETF RFC 3261 that defines a standard way for session setup, termination and media negotiation between two parties. It is widely used for VOIP (Voice-Over-IP) call signaling.
SIMPLE
SIMPLE is the Presence and Instant Messaging Extensions to SIP. It is defined by http://www.ietf.org/rfc/rfc3265.txt - IETF RFC 3265 .
SIPPING
It is an IETF working group chartered with defining conferencing extensions to SIP. SIPPING’s charter is to only define conference state event packages schema and explicitly stays out of defining the conference and media control mechanisms which is XCON’s charter. Centralized, star topology conference with the concept of a “focus” is the only topology that is in the scope of SIPPING’s work.
XCon
It is another IETF working group that is responsible for defining the Conference Control mechanisms consisting of the Conference Policy Control Protocol and Conference Media Control Protocol. It works in conjunction with SIPPING but is independent of SIPPING. One could envision using XCON mechanisms without using SIP, if necessary.
