Quite often the modeling tools used in the development lifecycle of Distributed Real-time and Embedded (DRE) systems are middleware-specific, where they elevate middleware artifacts, such as configuration options, to first class modeling entities. Unfortunately, this level of abstraction does not resolve the complex issues in middleware configuration process for QoS assurance. This paper describes GTQMAP (Graph Transformation for QoS Mapping) model-driven engineering tool-chain that combines domain-specific modeling, to simplify specifying the QoS requirements of DRE systems intuitively, and model transformations, to automate the mapping of domain-specific QoS requirements to middleware-specific QoS configuration options.
