Abstract

An increasing number of popular conferencing applications operate in a lightweight, infrastructure-independent ad hoc fashion and extend into the mobile realm. These P2P-type systems raise the demand for scalable, adaptive self organization of conferencing in a standard-compliant way. This paper addresses the challenge of distributed conference management with SIP and makes the following two contributions. First, we defne distributed operations of a conference focus by splitting the role of identifer and locator of the conference URI. Second, we extend the SIP conference event package by states that ensure a uniformly consistent view at the conference and facilitate resource-adaptive self organization.
