Abstract
In this paper we present a novel approach tomanaging real-time traffic in multimedia networks. Wefirst clarify the respective roles of the real-timecontrol system, the management system, and the network operator, and describe their interactions aimedat managing real-time services. Following thisframework, we introduce an architecture based on theconcept of managing network services by tuning theresource control tasks in the network control system. Todeal with the complexity of the network control system,we present the L-E model, a generic system-levelabstraction of a resource control task. We define high-level controls and visual abstractions forthe network operator which are supported by ourarchitecture. These concepts are evaluated on aprototyping platform, which includes a managementstation implemented on a graphics computer and ahigh-performance parallel machine running in real-timethe control and management systems of a large multimedianetwork. We conclude by describing the results of several experiments that illustrate thequantitative effect of management operations in a largemultimedia network that follows ourarchitecture.
