Description
Summary:This paper proposes an extension of the Deployment and Configuration of Component-based Distributed Applications Specification of the OMG (D&C) to support the development of applications with hard real-time requirements. The deployment plans of this kind of applications must include the configuration of the parameters that manage the components scheduling, in order to guarantee that the execution of the application always satisfies the specified timing constraints. The components must provide new metadata about their temporal behaviour and resource usage in order to schedule the applications in which they are used. The extension is formulated at platform independent model (PIM) level, based only on the models of component and application introduced in D&C, and on the requirements introduced by a reactive real-time paradigm. The extension is strictly compatible with the metamodel and the process defined in current D&C, adding some new modelling elements to the metamodel and new optional phases to the design application process, which are specific of applications with real-time requirements.
