AimRT 0.10.0-cpp Performance Test Report
Preface
The communication layer of AimRT is implemented via plugins. Officially supported communication plugins include iceoryx, ROS2, Zenoh, Http, Grpc, Mqtt, etc., covering common edge and cloud communication scenarios. These plugins provide the two common communication modes of publish-subscribe and request-response to enable inter-process communication both locally and across machines.
