RTI Connext DDS – Connectivity Platform for Industrial IoT

Connectivity software to streamline the most demanding IIoT systems.

RTI Connext DDS is the first connectivity framework designed for the demanding requirements of the IIoT. Based on the Connext Databus, RTI’s software allows applications to exchange data in real time and provides the non-stop availability and security essential for mission-critical systems. The Connext Databus enables applications to work together as one, integrated system, significantly reducing development, integration and maintenance costs.

Connext DDS has proven success in thousands of mission-critical systems including autonomous vehicles, connected medical devices and next-generation energy systems.



The Connext Product Suite simplifies application and integration logic with a powerful data-centric model, providing:

  • Performace
    Exceeds stringent real-time requirements and distributes high volumes of data with low latency.
  • Security
    Provides fine-grained security through standardized authentication, encryption and access control.
  • Scalability
    Integrates software modules and teams. Discovers data and devices automatically allowing for ease of system scalability.
  • Reliability
    Delivers nonstop availability with no single point of failure. Ideal for mission-critical systems.

RTI Connext DDS software includes the world’s leading implementation of the Object Management Group (OMG) Data Distribution Service (DDS) standard. DDS is the only open standard for messaging that supports the unique needs of both enterprise and real-time systems.
