Abstract

This paper proposes a strategy to manage the scheduling of real-time component-based applications that is fully compatible with the concept of component viewed as a reusable and opaque software module. The strategy is used on top of the RT-CCM technology, which extends the OMG’s LwCCM technology with the purpose of building real-time distributed component-based applications that can be executed on embedded platforms and with heterogeneous communication services. The strategy is based on three services included in the RT-CCM framework, which are implemented by the containers of the components, and are in charge of supplying the threads and the synchronization artifacts that the business code of a component requires to implement its functionality. During the components configuration process, these services are used to assign the values that lead to a schedulable application to the scheduling parameters of these threads and synchronization mechanisms, without having to know the internal code of the components. The assigned values are obtained from the analysis of the real-time model of the application, which is built based on metadata provided by the components and the elements of the platform.
