- As the name suggests, the Keep Alive feature is literally used to keep a network connection alive.
This term is not limited to MQTT, but also used in many other Protocols. In general, keep alive ensures that the connection between a server and a client is still open and both are aware of being connected.
This reduces network congestion and latency by ensuring that a single connection is used per client.
This is highly desirable, especially in the case of Machine to Machine communications, where the nodes have very limited resources.
