Data Distribution Service (DDS)


DDS logo
The OMG Data-Distribution Service for Real-Time Systems (DDS) is the first open international middleware standard directly addressing publish-subscribe communications for real-time and embedded systems.

DDS introduces a virtual Global Data Space where applications can share information by simply reading and writing data-objects addressed by means of an application-defined name (Topic) and a key. DDS features fine and extensive control of QoS parameters, including reliability, bandwidth, delivery deadlines, and resource limits. DDS also supports the construction of local object models on top of the Global Data Space.


DDS Portal:

The DDS portal is maintained by the OMG Data Distribution SIG (DDSIG). For the activities of the DDSIG and other events of interest to the community, please visit the EventCalendar and the DDSIG page.
