RTI Releases Data Distribution Service, Safety-Critical Edition

Real-Time Innovations (RTI), The Real-Time Middleware Experts, announced that it has released the first version of RTI Data Distribution Service, Safety-Critical Edition. This new, small-footprint version of RTI’s real-time messaging middleware is designed to meet safety certification standards such as DO-178B. Safety-Critical Edition was initially developed for use in satellite applications by the U.S. Air Force Research Laboratory (AFRL). However, Safety-Critical Edition is also ideal for communication within and between avionics systems and Unmanned Aircraft System (UAS) ground-control stations.

RTI Data Distribution Service, Safety-Critical Edition, is designed for communication within and between avionics systems and UAS ground-control stations.
Based on the Object Management Group (OMG) Data Distribution Service for Real-Time Systems (DDS) standard, Safety-Critical Edition provides a high-performance message bus for integrating distributed components of avionics systems, such as control systems, sensors, actuators and displays. Its loosely coupled integration approach significantly reduces long-term software maintenance costs by allowing individual subsystems to be added or upgraded without impacting existing software.

Safety-Critical Edition supports the standard DDS interoperability protocol and the Real-Time Publish-Subscribe Protocol (RTPS). Applications developed using Safety-Critical Edition can seamlessly communicate with other systems developed using RTPS-compliant DDS middleware. This allows military UASs to be easily integrated with net-centric combat systems, where DDS is widely used.

Safety-Critical Edition provides the core features that safety-critical systems need to perform high-performance data communication while minimizing code size, leading to a library size of approximately 130KB. This simplifies the task of meeting stringent safety and security certification requirements such as RTCA/DO-178B and Common Criteria for IT Security ISO/IEC 15408.

“RTI Data Distribution Service, Safety-Critical Edition provides a new level of capability for developers of distributed high-assurance systems,” said Bob Kindel, vice president of Engineering Services at RTI. “These applications are not supported by traditional enterprise messaging and integration middleware. In addition, Safety-Critical Edition can be integrated with existing RTI Data Distribution Service middleware in a transparent manner, allowing developers to satisfy each application’s capability, resource and assurance requirements.”

Pricing & Availability
RTI Data Distribution Service, Safety-Critical Edition will initially support Linux, Solaris, VxWorks 5.5 and VxWorks 6.4 operating systems. It is designed to be portable to other RTOS environments such as LynxOS and INTEGRITY operating systems.
