Mosquitto
Mosquitto is an MQTT message broker and IoT messaging server designed to route data between publishers and subscribers. It functions as a centralized network hub that enables lightweight communication between distributed sensors, controllers, and other internet-of-things devices.
The project includes an MQTT bridging gateway used to link separate brokers, allowing traffic to be routed and synchronized across different network locations or security zones. It also provides a client implementation for connecting to and interacting with the broker.
The system manages topic-based message routing and pub/sub exchanges, supported by broker access control and authentication. It includes capabilities for data persistence to recover state after restarts and a web-based interface for broker administration and monitoring.
Features
- MQTT Message Brokers - A broker that routes messages between publishers and subscribers using the MQTT protocol for lightweight device communication.
- Lightweight Messaging Protocols - Sending and receiving lightweight messages between distributed sensors and controllers using the MQTT protocol.
- MQTT Bridging - Linking separate message brokers together to share data across different network locations or security zones.
- Access-Controlled Brokers - Implements a security system to restrict broker entry and manage topic access via authentication files and plugins.
- IoT - A server designed for high-latency or low-bandwidth environments to exchange data between internet-of-things devices.
- Socket Communication - Handles persistent network connections using a lightweight binary protocol for low-overhead data transmission.
- Topic-Based Messaging - Matches incoming messages to a list of subscribers based on hierarchical string patterns to distribute data.
- State Persistence Layers - Writes session data and retained messages to disk to restore broker state after a system shutdown.
- Device Network Interconnectivity - Connecting multiple hardware devices across a network to share real-time state updates and control commands.
- Broker Disk Persistence - Avo MQTT capability to store message and state information in a database to recover data automatically after a system restart.
- MQTT Clients - Avo MQTT support for connecting clients to a message broker to send and receive data using dedicated client tools or libraries.
- Broker Bridges - Acts as a client to another broker to relay messages between two separate messaging networks.
- MQTT Libraries and Brokers - Open-source MQTT broker for v3.1/v3.1.1 protocols.
- Embedded Software Libraries - Open-source MQTT message broker.
- Embedded Utility Libraries - Open-source MQTT broker for messaging and IoT.
