Eclipse Zenoh
summary
Zenoh is a pub/sub/query protocol that runs from microcontrollers to data centers, implemented mostly in Rust with an MCU C port that is MISRA‑C compliant with only minor violations. It uses a 5‑byte minimal wire format, supports shared‑memory, UDP/TCP/QUIC and Bluetooth, and ships lightweight Rust routers that hit ~70 Gbit/s on 100Gbps hardware and ~6–10 µs latency in ultra‑low‑latency mode. Plugins provide storage, DDS/MQTT/ROS bridges and a JavaScript/WASM API; an AUTOSAR/ACLD certification path is in progress.
