It is a lightweight messaging and bi-directional protocol that works well in resource constrained network scenarios, such as low network reliability or low-bandwidth, or high-latent clients. It provides a simple way to send telemetry information between devices, or from devices to cloud. The protocol uses a publish/subscribe communication paradigm, and is used for Machine-to-Machine (M2M) communication and is widely adopted in the IoT.
