An electronic device includes multiple communication interfaces and a processor coupled to the interfaces. The processor is operable to identify an interface that can transfer data with a performance of a parameter that is closer to a desired performance level than the performance of the same parameter by another interface, and is operable to transfer the data via the identified interface. Such a device can, without operator input, select and transfer data via the communication interface that gives the best data-transfer performance relative to a particular parameter such as power consumption. Furthermore, if the performance of the selected communication interface changes during the data transfer, the device may, without operator input, identify an interface that offers better performance and switch over to transferring the data transfer via the identified interface. Moreover, the device may, without operator input, allow a number of software applications to share a lesser number of interfaces.
