What is DDS? »

Connecting Distributed Systems

Connext DDS Professional, based on a connectivity databus, offers a robust framework for developing and integrating mission critical systems. Its data-centric approach eases system integration by allowing applications to interact directly with data objects, freeing developers from having to address lower-level messaging or networking concerns.

Enterprise Integration Patterns

Supports the fundamental communication patterns in IIoT including data-centric publish-subscribe, request-reply and queuing.

DDS Standard Compliance

Full compliance with the OMG® DDS for Real-Time Systems standard, including the DDS API and network interoperability protocol (DDSI-RTPS).

Industrial Grade Performance and Reliability

Order-of-magnitude performance and reliability through benchmarked latency and throughput tests. Reliable multicast for scalable data distribution.
