To get started with DDS Quality of Service (QoS), the Astute DDS Shapes Demo is the perfect hands-on tool no coding required. The Shapes Demo is a game-like, interactive application that lets you explore DDS capabilities without having to do any programming, making it ideal for anyone new to DDS concepts. Once launched, you publish and subscribe to shape topics (Circles, Squares, and Triangles) on a shared domain and begin experimenting with policies immediately. You can configure Reliability, Durability, History, Filters, Ownership, and more, with the results clearly visible in how shapes appear, disappear, or replay on screen. RtiTwinoakscomputing

Astute DDS also makes it easy to validate interoperability across your DDS network. Run multiple Shapes Demo instances across machines on the same network and domain ID — because Astute DDS uses the standard RTPS wire protocol, participants discover each other automatically. QoS follows a request-offered model if a DataReader requests a higher level of service than the DataWriter is offering, the policies are considered incompatible and the DataWriter will not send data to the DataReader something you can observe directly when shapes stop appearing.
