Upgrade of the CERN RADE framework architecture using RabbitMQ and MQTT

AMQP (Advanced Message Queuing Protocol) was originally developed for the finance community as an open way to communicate the vastly increasing over-the-counter trace, risk and clearing market data, without the need for a proprietary protocol and expensive license. In this paper, we explore the possibility to use AMQP with MQTT (Message Queue Telemetry Transport) extensions in a cross platform, cross language environment, where the communication bus becomes an extendible framework in which simple/thin software clients can leverage the many expert libraries at CERN.
