Topic: SIP related protocols

   SIP

It is the industry standard protocol described in 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 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.

PSP

The PSP means Privacy Server Protocol.

The Privacy Server Protocol (PSP) project provides research into
large-scale distributed and automated negotiations for privacy and the
complementary negotiations for digital rights management. In the paper
world, the resulting agreements are essentially non-disclosure
agreements. 

PSP is an experimental protocol meant initially to extend the P3P and APPEL protocols to  

1. bilateral and negotiated agreements between client and server using HTTP or HTTPS. 

2. agreements that have scope in time (a start and expiration), 

3. agreements that have scope over digital and non-digital interactions (including mail and phone contacts), 

4. agreements that cannot be repudiated 

5. agreements that can be indexed by the server using server-only
Privacy Universal Identifiers (PUIDs). This is in contrast with the XNS
initiative which is using global PUIDs.
