In this talk we discuss a distributed QoS compilation and runtime system which represents a scalable and reconfigurable QoS framework for component-based distributed applications. Our QoS compiler encompasses a solution for an integrated methodology including QoS specification, QoS translation, as well as discovery, location, configuration, distribution and negotiation of services and their quality. We will present the entities, services and protocols of the QoS compiler framework, such as the application-to-component translators, component-to-resource translators, QoS-aware service discovery and contention-aware resource allocation protocols for the end-to-end QoS setup.
We have implemented the QoS compiler framework within our 2K^Q distributed middleware system and validated the feasibility on various distributed multimedia applications. The first prototype results show a feasible overhead of the runtime service instantiation and reconfiguration for different applications and their QoS requirements.
Klara Nahrstedt is an assistant professor at the University of
Illinois at Urbana-Champaign, Computer Science Department. Her
research interests are directed towards reconfigurable multimedia
services, multimedia protocols, multimedia security, middleware systems,
quality of service(QoS) provision, QoS routing, and QoS-aware resource
management in distributed multimedia systems. She is the coauthor of the
widely used multimedia book `Multimedia:Computing, Communications and
Applications' published by Prentice Hall, the recipient of the Early
NSF Career Award, the Junior Xerox Award, and then IEEE Communication
Society Leonard Abraham Award for Research Achievements.
Klara Nahrstedt received her BA in mathematics from Humboldt
University, Berlin, in 1984, and M.Sc. degree in numerical analysis
from the same university in 1985. She was a research scientist in the
Institute for Informatik in Berlin until 1990. In 1995 she received
her PhD from the University of Pennsylvania in the department of
