The OMG DDS (Data Distribution Service) is a standard for data
distribution which is widely used as the foundation for operational
systems such as air traffic control and management, combat systems,
distributed telemetry and control, etc. On the other hand, HLA (High
Level Architecture) is a communication and coordination standard which
is widely adopted in the distributed simulation community.
DDS is increasingly gaining adoption in distributed simulation,
especially for those systems that require high throughput, low
latencies and scalability. In addition, the use of DDS in simulation
provides native interoperability between operational and simulated
systems, thus eliminating integration overhead and complexities.
This presentation introduces DDS and HLA, provide an apple-to-apple
comparison between the two standards and show how DDS and HLA systems
can be seamlessly integrated together.
