Data Distribution Service (DDS) was successfully deployed and used during the first launch of the Orion spacecraft. DDS was able to intelligently distributed updates from thousands of sensors in real-time without a huge impact the network.
DDS was also configure with QoS parameters ( DURABILITY QoS Parameter and DURABILITY_SERVICE QoS Parameter ) to store all the data for later analysis and help filter (i.e., downsampling) the data for viewing on the HMI Stations in the flight control room.
