A method of optimizing communication and processing functions between disparate applications includes sending, from a first application to a disparate second application, a request message. In one embodiment, the method includes a downstream component that performs discovery of internal device components of the DC during initialization of the DC. An internal heat sink device is controlled according to content of the control command to control power ON or power OFF of a thermoelectric cooler of the heat sink device or to control power ON, power OFF, or change rotation speed setting of a heat sink fan in the heat sink device.
