Abstract

Distributed high-performance real-time systems must assure end-end Quality of Services (QoS). They thus require management and control technologies to support adaptation of applications to resource availability and adaptation of resources to applications' needs. This project aims to develop middleware and tools for adaptive management and control of distributed real-time multimedia systems. These include technologies for: (1) model-based adaptive management and control integrating network, system and application resource and their relationships; (2) unified instrumentation of resources to monitor QoS delivery and adapt resources and applications accordingly; and (3) policy-based end-end control of multimedia systems and applications. The project will develop a multimedia teleconferencing system based on the Internet's MBONE that demonstrates application of the developed software to assure end-end QoS by adapting to constrained and dynamically-varying resource availability. Success in this project would mean that we have developed general middleware and tools for adaptive management and control of distributed real-time systems, and that we can demonstrate their value in assuring end-end QoS in a realistic adaptive multimedia teleconference system.
