Transparent Conferencing Without Central Control - Demonstration of the DisCo Approach in P2PSIP,
In: Proc. of the 36th Annual IEEE Conference on Local Computer Networks (LCN'11, Demo Session), Oct. 2011.

Abstract: RELOAD is emerging as a standard from the IETF P2PSIP group that facilitates the design of manifold lightweight applications. P2P group conferencing is an example of particular interest to Internet users. In this demo, we present a RELOADbased protocol for Distributed Conference Control (DisCo) with SIP, as well as an implementation of DisCo and its underlying RELOAD stack. DisCo transparently addresses a conference through a single SIP URI while splitting its semantic of identifier and locator. Conference members are enabled to select conference controllers based on proximity awareness and to recover from failures of individual resource instances. Conference access control and membership coordination is achieved by a shared resource within the P2PSIP overlay that forms a basic primitive for enabling various coordination and notification schemes among distributed peers.
