Performance of a Publish/Subscribe Middleware for the Real-Time Distributed Control systems

Abstract: There’s a world of opportunity for distributed embedded and real-time applications. The list of applications goes on and on: military systems, telecommunications, factory automation, traffic control, financial trading, medical imaging, building automation, consumer electronics, and more. These applications must find the right data, know where to send it, and deliver it to the right place at the right time. The publish-subscribe paradigm according to DDS is the best fit to such complex distributed applications that require a powerful communications model.

Thus, the goal idea of this paper is to study the defaults within a network of publish-subscribe nodes occurring in a clustered middleware, in order to calculate the loss rates while allowing for the caching size. A simulator has been developed in order to fix metrics chosen in the theoretical part.
