ServiceDDS: A Framework for Real-Time P2P Systems Integration

In recent times real-time distributed systems have definitively become peer-to-peer organized. The common interactions are those of different real-time components dealing with sensors or actuators, implementing controllers, performing monitoring and surveillance tasks, and interacting between them in a dynamic decentralized way. There is a need for mechanisms that allow the integration of these independent components, saving development time while keeping their real-time capability. Services and events, thanks to their decoupled nature are perfect candidates for supporting these architectures. The data centric approach goes even farther, introducing a global data space that allows a flexible, decoupled and scalable coordination environment over which services and events can be added as specific interactions mechanisms inside this global data space, in order to support all the architectural possibilities. The Data Distribution Service specification provides a totally decentralized data-centric approach with real-time quality of service support. It is a perfect base upon which to develop a framework for the integration of real-time distributed architectures.
