The management of Quality of Service (QoS) in Information Systems allows their users to request services under certain conditions varying in function of their requirements but also in function of the current capabilities of the computing environment. The kind of the requirements and the notation used to formulate them vary with regards to application area and computing environment used. This paper presents a generic architecture that can manage QoS independently of the QoS domain and of the distributed environment used. We also introduce a QoS meta model (defined with a meta modeling facility – the so-called MOF – standardized by OMG) to exchange QoS models that allows a generic approach for QoS notation. By this way, this QoS management architecture is the first and only one platform which can manage all QoS contract properties (which are guaranty, observation, negotiation and composition) under a generic approach with regards of domain, environment and notation.
