MQTT is a open source protocol on top of TCP which is widely used in mobile communication and also for IoT (Internet of Things) today. This will add an open source implementation of MQTT so that it becomes easier for Netty users to implement an MQTT application. For more information about the MQTT protocol, read this: http://public.dhe.ibm.com/software/dw/webservices/ws-mqtt/mqtt-v3r1.html
