Abstract

Quality of service (QoS) is becoming an issue of increasing importance in distributed multimedia systems. This article presents an overview of the QoS issues involved in the design of such systems. QoS-related parameters can be identified in all system components. We will discuss QoS parameters found in communication protocols, operating systems, multimedia databases, file servers, as well as those directly concerned with the human user. The management of QoS parameters can be seen as an overall negotiation process involving various aspects such as dynamic adaptation and translation of parameters between different abstraction levels. First we present some approaches to this management found in the literature, then we describe features of our own QoS project.
