Paho/Paho MQTT Broker

Disclaimer: This project/idea is actually at the draft state.

Context

According to several discussions of the Paho mailing list (1)(2), it seems there a need for a Reference Implementation of a MQTT Broker, and also a need for a lightweight, embeddable and open sourced MQTT Broker running on the JVM.

The main goals are:

• Write a specification of a MQTT Broker
• Deliver a Reference Implementation

Key features of the MQTT Broker

Main features

The Minimum Viable Product (MVP) consists in:

• Lightweight
• Fully dedicated to MQTT
• Embeddable
• Some minimal level of authentication
• Support for secure/encrypted communications
• Running on the JVM

Other features

• Bridging
• Websocket connector
• Monitoring

TODO

• Write the MQTT protocol model classes (or extract the one from the MQTT Paho client)
• Write acceptance tests
• Write an implementation
