Multimedia Communication , Collaboration and Conferencing using Alkit Confero Mathias Johanson

This document presents Alkit Confero, a software framework for real-time multimedia communication, collaboration and conferencing. The different tools comprising the framework are described and the rationale behind the design decisions of the software architecture is discussed. Specifically, the protocols and standards that Confero adheres to are discussed. Other issues covered are multipoint collaboration support, session management and control, mobility support, media encoding and processing, and error resilience for real-time video communication.
