Paho/Paho MQTT Broker

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


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


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