applied opensplice | dds: a collection of use cases
DESCRIPTION
OpenSplice DDS is the real-time and ubiquitous data-sharing infrastructure at the core of an increasingly large number of systems across application domains. With applications in Power Generation, Large Scale SCADA, Air Traffic Control and Management, Smart Cities, Smart Grids, Vehicles, Medical Devices, Simulation, Aerospace, Defense and Financial Trading, it is highly likely that, one way or another, you’ve already been consuming goods or services produced by infrastructures based on OpenSplice DDS! This slideshare will (1) present some of the most significant OpenSplice use cases across application domains, (2) highlight the role played by OpenSplice along with the commonly adopted architectural patterns and (3) explain the benefits brought by OpenSplice DDS and the product features that make the difference when compared to other technologies.TRANSCRIPT

DDS & Next Generation VetronicsNext generation Vetronic systems, across the globe, such as the UK GVA, have :
☐ Adopted a data-centric system architecture
☐ Defined the Common Data (Topic) Model that captures data exchanges (with proper QoS) between subsystems
☐ Adopted/Mandated DDS/DDSI as the interoperable real-time data sharing standard
DDS has provided the data back-bone that ease integration, enables extensibility and ensures the right level of scalability and performance.
