Performance Evaluation of an XM L-Based Conference Control Protocol for Centralized VoIP Conference

For communication between heterogeneous conference systems, it is important to build a conference control protocol independent from signaling protocols. We simulate an "L-based conference control that is under consideration as a standard mechanism. We describe the framework and operations for easy implementation in heterogeneous conference systems. The simulation results show that the proposed control protocol provides a consistent service for an increasing number of conferences and participants in small to mid-size centralized conferencing.
