Architecture Overview

FastBee uses a layered architecture for extensibility and maintainability.

Layers

Layer	Purpose	Components
Access	Protocol adaptation & connection	MQTT Broker (Netty), SIP Server
Business	Core IoT logic	Product/Device/ThingModel/Scene/Rule
Service	Common capabilities	Auth, cache, messaging
Data	Persistence & storage	MySQL, Redis, TDengine
Presentation	User interfaces	Vue Web, UniApp Mobile

Core Flows

• Data Report: Device → MQTT Broker → Routing → Rule Script → Business → Storage
• Command Dispatch: User/API → Business → MQTT Broker → Device
• Video: Camera → SIP → ZLMediaKit → Web/APP

Deployment

• Single-node: All services on one server (< 1000 devices)
• Distributed: Separate web/API/database servers (1000-5000 devices)
