General Overview Of Protocol Layer
Protocol Layer is the mid level layer, which receives various requests from Application Layer and sends commands to the Cash Flow Device according to the requests. The Cash Flow Device then echo backs some values against the requested command to the Protocol Layer. Finally Protocol Layer sends those values to the Application Layer.
Figure-1 shows how Application Layer communicates with Protocol Layer and Protocol Layer communicates with the Cash Flow Device.
Protocol Layer Architecture
Protocol Layer directly handles all the requests come from Application Layer and further processes them to send to the Cash Flow Device. Protocol layer provides the flexibility to select a specific Protocol out of multiple supported protocols and communicate with the device with the selected protocol. The various portion of Protocol Layer are described below:
