ARENA’s PubSub is supported by a MQTT Mosquitto broker, modified to keep track of connected clients and data flows. This is organized into a graph that is available to users and, more importantly, to the runtime supervisor, ARTS (see the following paragraph). Take a minute to view the ARENA network’s connections as you move around in the ARENA on our Network graph. Clients connected (orange square), client subnets (gray box), MQTT topics (blue circle), and their current relationships and throughput (white arrow) can be visualized.
