Gateway Module

Tips

The gateway module was introduced in version 2.0. It brings together protocol decoding and encoding, data forwarding, data calculation, and persistent storage.

Module Overview

The gateway module is responsible for processing device-side data before it enters the business system. It decodes protocol packets, normalizes messages, forwards data to the correct channel, and supports later calculation and persistence.

• gateway-boot is the gateway startup module.
• fastbee-mq is the core gateway message module.

Gateway Data Entry

Device data enters the gateway through the protocol access layer, then flows into the message channel for parsing, routing, and consumption.

Message Queue Modes

The gateway message layer supports two modes:

1. redisChannel with a local queue.
2. RocketMQ.

The mode is switched through configuration. redisChannel is used by default.

cluster:
  enable: true
  type: redis

Redis Channel Flow

After data is forwarded through the data interface, it is distributed by channel. The following diagrams use redisChannel as the example.

Register the required channels:

Distribute messages after they enter the channel:

Finally, messages enter the consumer queue where business data processing is performed.
