Object-oriented modeling of multimedia conferencing systems

Multimedia conferencing has been making significant progress in recent years. There are many research projects and prototypes of this advance in interactive communications, however there is still no general abstract model. This thesis is primarily concerned with developing such a model that covers the major functions employed in a conference. Object Modeling Technique (OMT) is adopted here in describing both the static and dynamic aspects of this model. A relevant authorization system is also considered in this thesis. This system includes the description of an authorization model with general administration policies.
