MQTT is an ISO standard (ISO/IEC PRF 20922) [1] publish–subscribe-based messaging protocol.It works on top of the Internet protocol suite TCP/IP. It is designed for connections with remote locations where a "small code footprint" is required or the network bandwidth is limited.
The broker can support both standard MQTT and MQTT for compliant specifications such as Sparkplug. [21] This can be done with the same server, at the same time and with the same levels of security. The broker keeps track of all the session's information as the device goes on and off, in a function called "persistent sessions".
Message brokers that are purpose built to achieve time-bounded communications with end-to-end predictability allow for the development of real-time systems that require execution predictability. Frequently systems with real-time requirements involve interaction with the real world ( robotics , vehicle automation , Software-defined radio , et al.)

ZeroMQ (also spelled ØMQ, 0MQ or ZMQ) is an asynchronous messaging library, aimed at use in distributed or concurrent applications. It provides a message queue, but unlike message-oriented middleware, a ZeroMQ system can run without a dedicated message broker; the zero in the name is for zero broker. [3]
RabbitMQ is an open-source message-broker software (sometimes called message-oriented middleware) that originally implemented the Advanced Message Queuing Protocol (AMQP) and has since been extended with a plug-in architecture to support Streaming Text Oriented Messaging Protocol (STOMP), MQ Telemetry Transport (MQTT), and other protocols.
