Abstract
One embodiment of the present invention provides a system that facilitates communicating between device drivers within a computing system. The system first determines a need to invoke a function on a remote device from a local device driver, wherein the local device driver is not able to perform the function on the remote device. Once the need has been determined, the system obtains a unique identifier for a remote device driver capable of performing the function on the remote device, and uses the unique identifier to facilitate invoking the function in the remote device driver from the local device driver.
