Abstract
Quality of service (QoS) support has been a hot research topic in multimedia databases, and multimedia systems in general, for the past several years. However, there remains little consensus on how QoS support should be provided. At the resource-management level, systems designers are still debating the suitability of reservation- based versus adaptive QoS management. The design of higher system layers is less clearly understood, and the specification of QoS requirements in domain-specific terms is still an open research topic. To address these issues, we propose a QoS model for multimedia databases. The model covers the specification of user-level QoS preferences and their relationship to QoS control at the resource-management level, and is applicable to adaptive and reservation-based systems. In this paper we present the model, discuss the implications it has for multimedia database design, and describe a practical implementation of it.
