Quality of service management for multicast applications using MPEG-4/DMIF.

Abstract

The main objective of this thesis is to introduce an approach of quality of service management for multicast multimedia applications based on the Delivery Multimedia Integration Framework (DMIF) of MPEG-4 as a session management protocol. We consider that the distributed multicasting applications may involve a large number of users, therefore, a single quality of service level may not be appropriate for all participants. It is necessary to distribute part of the QoS management process and allow each user process to make certain QoS decisions based on its local context. This report gives an overview of some background knowledge, presents the design of a teleteaching system that uses our paradigm for QoS management, explains how DMIF can be adapted as a session protocol for such an application, and finally, provides the implementation details of the system.
