This is a list of drafts we proposed in order to examines the requirements, propose the framework and design a synchronization protocol between a distributed conferencing entity and the centralized system it's connected to:

The first one examines the requirements for an architecture capable to provide a distributed conferencing service. It draws inspiration from a number of existing research efforts inside the IETF, mainly in the context of both the SIPPING and the XCON WGs.
The second presents an architecture capable to move the XCON scenario towards a distributed framework. In such an architecture a number of entities are used to manage conference setup in the presence of clients which are distributed across a geographical network. Each managing entity plays the role of a conference focus as defined in the XCON working group documents.
Finally, the third one defines the requirements needed fro the interaction between the centralized conference focus and the distributed conference focus.
