Connext DDS Cert

Safety-Certifiable Connectivity Platform based on the Object Management Group (OMG) Data Distribution Service (DDS) standard, with small memory footprint, bunled source code, and DO-178C Level A Certification Package.


Connext DDS Cert is a safety Certifiable communications infrastructure with an available DO-178C Level A Certification Package. Based on the Object Management Group (OMG) Data Distribution Service (DDS) standard, its run-time libraries provide developers with high-level publish/subscribe communication APIs 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.
