Quality of service issues related to transforming platform independent models to platform specific models

The UniFrame research project is proposing a Unified Component Meta Model Framework (UniFrame) that includes quality of service (QoS) contracts. Today it is the role of the software architect, based on experience, to design platform specific solutions that will meet QoS requirements. As we refine algorithms for model transformations, we must identify these QoS-aware design patterns and utilize them during model transformations. Our research includes supporting and participating in the exploration of generative techniques as they relate to QoS requirements (both static and dynamic) and the standardization of QoS-aware transformations. This paper explores how QoS requirements can impact decisions related to model transformation (using UML for Platform Independent Modeling and ISO IDL for the Platform Specific Model). It explores a series of QoS related design issues that must be considered as platform independent models are refined for specific component platforms.
