48 -In this MQTT forward feature, the key point is how the gateway process the sensor data.

51 -=== 3.2.1 Upstream ===
52 -
53 -Assume there are two sensor nodes, their ID are Node1 ID: 6734 , Node2 ID: 7456. In the remote MQTT broker there are two topics: Topic1: /channel/765800, Topic2: /channel/367860. We can set up in the gateway to map Node1 to Topic1 and Node2 to Topic2. So when there is a sensor data from Node1, the gateway will forward the data to Topic1, when there is sensor data from Node2, the gateway will forward to Topic2.
