A Web-Services based Conference Control Framework for Heterogeneous A/V collaboration

Conference control has been studied for years but most researches focus on homogenous A/V collaboration. There is no conference control framework for integration of multiple A/V systems such as H.323, SIP and AccessGrid. In this paper, we propose a web-serviced based scalable conference control framework for such heterogeneous collaboration system. We also implemented a prototype to verify and refine our framework.
