RTI Connext® 6 is the newest release of the RTI Connext product suite. This release includes updates to all products including Connext DDS Professional 6.0, Connext DDS Secure 6.0 and Connext DDS Micro 3.0. It features new capabilities specifically designed for the most demanding distributed systems, such as those in aerospace & defense, healthcare and automotive

Introducing Connext 6 


The healthcare industry is undergoing a digital transformation. Healthcare and medical device manufacturers are developing systems that harness the power of real-time data. These connected healthcare systems – communicating seamlessly and securely – have the opportunity to improve patient outcomes, reduce medical errors and lower healthcare system costs. To realize these benefits, the healthcare industry must collect and transport unprecedented amounts of data in real time, across a large number of diverse devices. Additionally, developers of medical-grade products must ensure interoperability throughout the system, meet stringent security requirements and provide the foundation for highly reliable communications with no single point of failure. 

RTI Connext 6 is the first solution that provides device manufacturers with the medical-grade connectivity technology needed to address critical design challenges faced in developing complex, connected healthcare systems.

What's New

RTI Connext 6 is the first connectivity solution on the market to satisfy the demanding, system-level requirements of the healthcare industry. For example, developers can build their systems with massive scalability without compromising performance or security. This enables them to focus on their core competencies – system development, data analysis and user experience – to develop products faster and with lower costs.


  • Large Data Distribution allows efficient streaming of high-bandwidth data from many disparate sources and sensors, important in both 3D imaging and connected healthcare applications.
  • Data Extensibility supports longevity and evolution of large, expensive medical equipment, such as large CT scanners – enabling interoperability across generations of subsystems and products.
  • Data-Centric Gateways provides intelligent data routing for greater efficiency, improved scalability and easier integration with legacy medical devices and enterprise systems.
  • Enhanced Performance reduces CPU overhead and end-to-end latency in distributed applications – a necessity for haptic control loops in surgical robotic systems and fusing real-time, near-patient data for Clinical Decision Support (CDS).

Decreased Time to Market

To design the connectivity software required for medical-grade systems, medical device manufacturers have the choice of designing the software in house (which is expensive, difficult and time consuming), or adopting an off-the-shelf-solution. Those that choose a well-documented, off-the-shelf connectivity framework like Connext DDS are able to meet development and security requirements, solve specific design challenges, and get to market faster.


A medical-grade connectivity framework is one that a medical device manufacturer can embed into a regulated device or system and receive the required regulatory clearance. RTI Connext 6 is medical grade because it is designed for regulatory clearance, providing customers with the documentation needed throughout the process. It also offers a pathway to product longevity by enabling manufacturers to evolve and extend their data models over time without breaking backward compatibility. Lastly, Connect 6 is compliant with the latest Object Management Group (OMG) DDS Security specification.

Increased Security

In healthcare environments, maintaining the highest level of security is of the utmost importance. The Connext DDS connectivity framework allows medical device manufacturers to secure the data in-use down to the data-type level, meeting the requirements of the FDA cybersecurity guidance and minimizing the impact to system performance.

The First Connectivity Software for Highly Autonomous Systems

Advancements in artificial intelligence and sensor technology are driving autonomy across the IIoT. Yet these highly and fully autonomous systems pose challenges that are unaddressed by traditional approaches to data communications. In particular, AI algorithms must efficiently assimilate high volumes and high rates of data from disparate sensors while assuring resilience, security and safety. RTI Connext® DDS is the first connectivity framework designed for these demanding requirements.

RTI Connext 6 features updates to all of the products in the Connext suite, including Connext DDS Professional 6.0; Connext DDS Secure 6.0; and Connext DDS Micro 3.0.


  • Efficient High-Bandwidth Data Distribution for increased throughput and reduced latency.
  • Integration with Standardized Frameworks and Platforms to ease integration between OEMs and suppliers, from research through production.
  • Safety Certification Pathway to meet the stringent requirements of ISO 26262 ASIL-D, reducing risk, time and project costs.
  • Built on Data Distribution Service (DDS), the proven connectivity standard used by AUTOSAR Adaptive and ROS2 for autonomous vehicles.

What's New

Connext 6 supports autonomous system development from research to production. It is the first standards-based connectivity framework to handle the complex integration and data distribution challenges of sensor fusion applications in autonomous systems. It enables level 4 and level 5 autonomy through fast, scalable, and efficient distribution of high-bandwidth sensor data. Integration with standardized software frameworks, like AUTOSAR Adaptive and ROS, combined with a path to safety certification saves months of development time.
