Abstract
In this paper, we present a novel approach to managing real-time
traffic in multimedia networks. We first clarify the respective roles
of the real-time control system, the management system, and the
network operator, and describe their interactions aimed at managing
real-time services. Following this framework, we introduce an
architecture based on the concept of managing network services by
tuning the resource control tasks in the network control system. To
deal with the complexity of the network control system, we present the
L-E model, a generic system-level abstraction of a resource control
task. We define high-level controls and visual abstractions for the
network operator which are supported by our architecture. These
concepts are evaluated on a prototyping platform, which includes a
management station implemented on a graphics computer and a
high-performance parallel machine running in real-time the control
and management systems of a large multimedia network. We conclude
by describing the results of several experiments that illustrate the
quantitative effect of management operations in a large multimedia
network that follows our architecture.
