Real-time networking software for mission-critical applications

Real-Time Innovations Inc. (RTI) in Santa Clara, Calif., is offering the NDDS 4.0 implementation of the Object Management Group’s (OMG’s) Real-Time Data Distribution Service (DDS) standard. NDDS 4.0 has been running as a beta release in nearly 50 mission-critical applications. The general-access release is available for these sites, as well as for hundreds of applications running NDDS 3.x in military, aerospace, transportation, finance, and industrial automation. New objectives and features in NDDS 4.0 include pluggable transports that support media from wireless to switched fabrics; direct end-to-end messaging that eliminates context-switch delays and supports message prioritization; preallocated memory that prevents allocation and fragmentation delays; applications that do not share address space through the middleware; and dedicated buffers that immunize against corrupted shared memory. The DDS standard defines high-performance, configurable publish-subscribe networking. It addresses the needs of data-critical applications.
