Connext DDS Cert

Safety-Certifiable Connectivity Platform

RTI Connext® DDS Cert is a connectivity framework that enables Industrial (IoT) system architects to build safety-critical IIoT systems of systems. Connext DDS Cert is the only off-the-shelf connectivity framework certifiable for the highest levels of the DO-178C standard.

Based on the Object Management Group (OMG) Data Distribution Service (DDS) standard, its run-time libraries prvide developers with high-level publish/subscribe communication API's that simplify application logic while eliminating the need for custom networking code. This can save tens of thousands of lines of application software and the need to develop its accompanying certification artifacts, avoiding years of effort and millions of dollars in cost. 

Slash Avionics Costs with Connext DDS Cert

Highlights

  • Compliance with stringent safety certification standards
  • Reusable certification evidence available for:
    • DO-178C DAL A
    • ISO 26262 ASIL D
    • IEC 61508 SIL 3
    • Other Safety Standards
  • Eliminates custom communication and networking code
  • High-level publish/subscribe APIs to simplify application logic
  • Small memory footprint
  • Bundled source code for easy portability across operating systems and CPUs
  • Completely decentralized architecture with no message brokers
  • UDP multicast for efficient broad data distribution
  • Pluggable transport interface for other connection types
  • Support for FACE Security Profile 
  • Availability of FACE Transport Services Segment (TSS)

Because of demanding requirements, safety-critical systems have traditionally used custom software to communicate between different subsystems, applications and modules. Developing this software and any necessary certification evidence is time consuming and expensive. The software must support systems' real-time, reliability and resilience requirements. It must also be certifiable. On top of this, producing certification artifacts can take months to years of additional effort.

Complete Commercially Supported Certification Package

Connext DDS Cert significantly reduces the time and cost required to develop distributed safety-critical systems. It includes an off-the-shelf connectivity library that eliminates the need to develop custom communications code and any requisite certification evidence. It is available with a complete Certification Package for DO-178C Design Assurance Level A (DAL A), one of the most stringent safety standards. This evidence also provides the basis for certification to other standards including IEC 61508 for industrial systems, IEC 60601 for medical devices and ISO 26262 for automotive systems.

Advanced Publish/Subscribe Capabilities with Real-Time Quality of Service

Connext DDS Cert replaces traditional low-level networking code with high-level publish/subscribe Application Programming Interfaces (API). Modules communicate by simply publishing the data and commands they produce and subscribing to the data they need. Connext DDS Cert handles all of the communication details, including discovery and presence detection, messaging, routing, redundancy, failover, serialization, and state synchronization for late joiners. For time-critical applications, Connext DDS Cert provides real-time Quality of Service control and visibility.

Compliance with Industry-Leading Standard – DDS

Connext DDS Cert is a completely standards based solution. Its API and network protocol support the OMG DDS standard. Application code is portable across Connext DDS Cert and other DDS implementations. Connext DDS Cert also interoperates peer-to-peer with Connext DDS Professional and Connext DDS Micro, and with other DDS solutions using RTI Routing Service as a bridge.

Open Architecture and Interoperability

Support for well-defined and interoperable interfaces make Connext DDS Cert an ideal foundation for a modular open systems architecture (MOSA)—reducing ongoing integration, maintenance and upgrade costs. Its DDS compliance aligns with many Open Architecture (OA) initiatives, including the Future Airborne Capability Environment (FACE), UAS Control Segment (UCS) Architecture, and Open Mission Systems (OMS).
