FairCom MQ Concepts

FairCom MQ concepts about MQTT, message queues, message brokers, publishing and subscribing to topics

FairCom MQ is a high-speed, highly reliable, low-maintenance MQTT broker written in C++ with a built-in JSON/SQL database. It fully supports MQTT 3.1, MQTT 3.1.1, and MQTT 5. It is suitable for mission-critical solutions collecting data on the edge of the network, such as manufacturing, remote facilities, smart hospitals, smart cities, and smart buildings.

MQTT concepts

MQTT is a client-server messaging protocol for software to publish and subscribe to messages. It is optimized for the Internet of Things (IoT). Its key features are simplicity and ease of use.

Broker forwarding

MQTT forwards messages from one broker to another to form a chain. This is a great way to move information across data centers.

Differentiating features

Many features of FairCom MQ make the FairCom server distinctly different from other database servers.

System topics

FairCom MQ automatically publishes system messages to three topics.

Message Queueing Telemetry Transport (MQTT) is the Internet standard protocol for publishing and subscribing to messages that are sent to topics on an MQTT broker (see MQTT.org for more information).

Internet of Things (IoT) uses Internet protocols to connect things to software. Things include devices, equipment, appliances, vehicles, and so forth.

Each thing must contain an embedded computer processor and must use an IoT protocol, such as MQTT, to communicate with software.

Since 2014, MQTT has become the standard Internet protocol for IoT. MQTT is necessary because devices need to push information when it is created, such as a status update, an alert, telemetry, or a command. MQTT is used in IoT because HTTP is a request/response protocol that cannot push information.
