With the arrival of multimedia services via the network, particulary the Internet and e-commerce, the study of multimedia transmission over various network technologies has been the focus of interest for research teams all over the world. The previously antagonistic QoS (Quality of service) management in B-ISDN (Broadband integrated service digital network) and IP-based network technologies are now part of an integrated approach at the core network (with MPLS) and the access network (with ADSL).
This is expected to lead to new intelligent approaches to traffic and congestion control at different levels of the network to provide the end user with QoSquality customized multimedia communications. This publication addresses the différent approaches to managing mutimedia networks and services, and examines the results of recent research that has brought about significant advances in this important area.
