A component-based real-time architecture for distributed supervision and control applications

Nowadays, the development of flexible and interoperable software platforms for industry is an important issue. The CCM model captures two paramount features of such platforms, as it combines component-based middleware (easy composition of new applications and maintainability) and the openness of the CORBA standard. Though there exist an implementation of CCM devoted to real-time systems (CIAO platform), much effort is needed to validate its use in the real-time industry scenario. This paper contributes to this goal by presenting the design and implementation of a new framework over CIAO, which conforms to the DAIS standard (data acquisition from industrial systems). We discuss our design decisions and show how the framework can be used to develop distinct S&C applications. We also discuss implementation details and show performance data from a series of experiments.
