Towards a Reflective Middleware Framework for QoS-Enabled CORBA Component Model Applications

Overview Although existing CORBA specifications, such as Real-time CORBA and CORBA Messaging, address many end-to-end Quality-of-Service (QoS) aspects, they do not define strategies for configuring these QoS aspects into applications. This paper presents three contributions to the study of reflective middleware for QoS-enabled component-based applications. It outlines strategies for selecting optimal communication mechanisms reflectively, re-factoring QoS aspects from components into their containers to adaptively respond to changing QoS requirements and conditions, and dynamically loading/unloading and activating/deactivating component implementations.
