An Approach to Quality of Service Management for Distributed Multimedia Applications
Abdelhakim Senhaji Hafid, Gregor von Bochmann · 1995
Emerging high-speed networks and powerful end-systems give rise to a new class of applications such as video-on-demand and teleconferencing. Such applications are very demanding on Quality of Service (QoS) because of the isochronous nature of media they are using. To provide QoS support on an end-to-end basis, the need for the integration of network, transport, and operating services arises. Thus to support the new emerging services, an end-to-end QoS management is required. This paper deals with QoS management for multimedia applications by taking remote access to multimedia database as a case study. The example application is introduced and the entities involved in QoS provision are identified. QoS management activities are defined and a basic QoS management architecture for multimedia applications is presented. A general framework for QoS (re)negotiation is defined and an instantiation of this framework in the context of the example application is presented.
