This paper explores the features of Communications Middleware (including DDS) providing a foundation of the role of middleware in software development.
The Laboratory for Advanced Collaboration (LAC) chose to utilize the Twin Oaks Computing CoreDX DDS University Licensing Program for an ongoing project: ContextNet. Project ContextNet aims at enabling communication services for large and wide scale exchanges, including on-line monitoring or coordination of mobile device activities, and information sharing through social networks. These entities may be users of portable devices (e.g. smartphones), vehicles, or moveable gadgets.
This video shows how easy it is to deploy a CoreDX DDS enabled application to the Android phone. The Data Distribution Service interoperability tool 'Shapes' from Twin Oaks Computing is imported into the Eclipse IDE, configured, built, and loaded to an Android emulator as an example application.
DDS is increasingly beiong adopted as the middleware and data-model of choice for vehicle integration and interoperability. Testament to that are the recent directives from the UK MOD (Def Stan 23-03) that standardize on DDS for the Land Data Model and the messaging integration, as well as the US OSD Unmanned Control Segment (UCS) architecture that also directs the use of DDS for Unmanned Vehicle integration.
Three vendors: RTI, PrismTech, and TwinOaks Computing performed a live interoperability demo between their respective products.
The demo showcased 7 scenarios:
- Basic interoperability
- QoS Matching
- Quality of Service: DURABILITY
- Time Based Filters
- Quality of Service: RELIABILITY
- Intermittent Connectivity
- Multiple Topics, Keys & Content Filters
And demonstrated interoperability for:
