A virtual and distributed control layer with proximity awareness for group conferencing in P2PSIP

Alexander Knauf, Gabriel Hege, Thomas C. Schmidt, Matthias Wählisch
2010 Principles, Systems and Applications of IP Telecommunications on - IPTComm '10  
There is an increasing demand to access voice or video group conferences without the burden of a dedicated infrastructure, but at any place and in an ad hoc fashion.  ...  We propose a P2P-signaling protocol scheme for a distributed conference control with SIP, that splits the semantic of Identifier and Locator of a SIP conference URI in a standard-compliant manner.  ...  Membership is achieved by joining multicast groups and control information are learned out of band or from the application transport protocol (e.g., RTCP [5] ).  ...
