IoT Agent - HTTP & MQTT command (southbound)

Hello,

To me it's not clear if a device needs to take the initiative (pull) to get southbound/commands from the IoT Agent (http transport) or the IoT Agent takes the initiative (push) to the device?

For MQTT I suppose the IoT agent subscribes to the MQTT (Mosquitto) broker and subscribes and/or publishes to the MQTT broker?

Thanks for the clarification.

Guy
