Data Distribution Service
summary
Company uses DDS to replace vendor-locked middleware and glue PLCs into a Ulstein IAS Mk II automation that exposes all I/O on a DDS network, cutting bespoke wiring and configuration and speeding development. Implementation uses RTI DDS with IDL-generated C++ on Linux (Boost), a central logger that subscribes to everything, and DDS discovery and QoS for deadlines, reliability and content filtering. Demo shows Raspberry Pis as publisher/subscribers with ownership handover after 5s and late-join history; security is not implemented.
