Connext DDS is designed to address the performance, scale and resilience requirements of the IIoT. The middleware delivers low-latency and real-time quality-of-service to monitor and control physical-world processes, with full-time availability and security, for mission-critical systems. Connext DDS provides connectivity capabilities optimized for IIoT systems, such as messaging libraries, an adapter framework and powerful tools. Unlike a traditional database, Connext DDS is a completely decentralized software data bus. The connectivity platform supports all of the fundamental communication patterns used in the IIoT. Given the long lifecycles of industrial systems, it is suited to incremental adoption. The scalable, reliable and secure integration bus connects new and existing assets. RTI Connext DDS claims order-of-magnitude performance and reliability advantages over other messaging and integration middleware on every supported platform.
Connext DDS complies with the Object Management Group (OMG) Data Distribution Service (DDS) for Real-Time Systems standard. It supports both the DDS application programming interface (API) and network interoperability protocol (DDSI-RTPS). DDS is the only messaging standard designed specifically to meet the requirements of timing-critical systems. It can deliver over 50 times the performance of IT standards such as JMS, MQTT, AMQP, XMPP and Web Services.
