DCON architecture Distributed Conferencing (DCON) Explicitely recalls XCON (Centralized Conferencing) Orchestrates the operation of a set of XCON “clouds” Overlay network interconnecting the clouds Intra-focus communication  Still based on XCON protocols Inter-focus communication  Exploits Server-to-Server (XMPP) Requirements  Focus discovery  Initialization information & spreading of conference events  Setup and managing of distributed conferences  Transparent dispatching of natively centralized protocols among the involved conferencing clouds
