Quality Information Modeling for QDD Support

Summary Nowadays QoS (Quality of Service) architectures have been required to support most of distributed applications, particularly in wide environments like the Internet. In this context, it aims to be more interesting to offer services according to user requirements and expectations. We will be able to talk about Quality Driven Delivery (QDD) when we consider the users expectations in terms of non-functional requirements like cost. In this paper, we propose a framework to support QDD in distributed multimedia systems that enable QoS specification, QoS mapping and more generally QoS decisions in order to provide resources allocation and adaptation. We focus on the quality information management to support QDD while proposing an UML diagram for QoS information model.
