Abstract

The INO340 Control System (INOCS) is being designed in terms of a distributed real-time architecture. The real-time (soft and firm) nature of many processes inside INOCS causes the communication paradigm between its different components to be time-critical and sensitive. For this purpose, we have chosen the Data Distribution Service (DDS) standard as the communications middleware which is itself based on the publish-subscribe paradigm. In this paper, we review and compare the main middleware types, and then we illustrate the middleware architecture of INOCS and its specific requirements. Finally, we present the experimental results, performed to evaluate our middleware in order to ensure that it meets our requirements.
