ROS 2 QoS profiles decide whether your sensor data reaches its subscriber. Learn the trade-offs between BestEffort and Reliable delivery, how to size buffers, and how to debug mismatched connections.
Learn how NPSS architectures eliminate Head-of-Line blocking and packet starvation using decoupled planes and Weighted Fair Queuing (WFQ) for wire-speed performance.
Learn how to use OpenStack Cinder Volume Types and QoS specs to cap IOPS, prevent noisy-neighbor contention, and verify where enforcement actually happens.
Guidance on choosing QoS 0, 1, or 2 in Node-RED MQTT nodes, with trade‑offs, a comparison table, and a function‑node example for per‑message QoS override.
ROS 2's DDS middleware replaces ROS 1's central master with decentralized discovery, but introduces QoS configuration complexity. This architecture note covers domain partitioning, per-topic QoS tuning, silent failure modes, and concrete verification commands for multi-robot deployments.
Learn how ROS 2 intra‑process communication cuts latency and CPU use by letting nodes share messages via shared memory instead of DDS.
