Network Topology and Multiple Gateways Gateway


The above topology indicates that Gateways G2 and G3 communicate with G1 via LAN/WAN.
WHat are components on the Gateways that are specifically involved?
Do I assume correctly that it is MQTT Broker on G1?
Are G2 and G3 have to run MQTT Clients or if they run MQTT Brokers as well the latter once will communicate the positioning data to MQTT Broker on G1?
So G1 MQTT Broker need to subscribe to G2 and G3 MQTT Topics?
Anyway, it would be great to read somewhere how all this interaction between Gateways works…

I saw that post but it explains very little:

  1. The Daemons will forward their data to a DWM Proxy (there will be only one Proxy for the whole network) which will work as data filter for the uplink and router for the downlink data.
  2. The DWM Proxy will forward the filtered data to the MQTT Broker.

So based on that there will be only one Proxy, running specifically on G1?
…and this Proxy will receive data from Daemons on G2 and G3?
…and then this Proxy will forward the data to MQTT Broker running on G1? (how is it done internally)
What do Daemon use when they communicate with Proxy?
Does Proxy has internal MQTT client in order to communicate with MQTT Broker? or any other comm protocol?
