WebSphere MQ Telemetry - Middleware News
WebSphere MQ Telemetry supports the connection of telemetry devices to WebSphere MQ. Telemetry devices include, but are not limited to, sensors and actuators, mobile phones, smart meters, medical devices, vehicles, and satellite locations. The connection is made possible by the WebSphere MQ Telemetry Transport (MQTT) protocol.
MQTT is an open message format and protocol that you can use to transfer messages from telemetry devices to a message server or vice versa. It can run on constrained devices and across constrained networks. Constraints on devices include low memory and processing capability. Constraints on networks include low bandwidth, high latency, high cost, and fragility. MQTT has been successfully deployed in various industries, including energy, utilities, and the retail sector.
