mqtt in osi layer

[Mr. Pandey]

I want to know how data go from application layer to physical layer and vice versa in the case of MQTT protocol.

Hi Rajesh,

MQTT is an application layer protocol that runs on top of an underlying transport protocol such as TCP. In that sense, it is the same as other application layer protocols such as HTTP.

I'm not sure what sort of detail you are looking for - the OSI model is a conceptual one, the exact mechanism of how data is passed between layers will depend on the implementation stack.
