Abstract
A Hardware Abstraction Layer (HAL) for a target computing device that is equipped with an Application Specific Integrated Circuit (ASIC) or other hardware element that provides forwarding and/or switching capability is used to analyze an abstract candidate device model. The abstract candidate device model is received from a controller and specifies intended forwarding behavior for the target device. The HAL analyzes the abstract candidate device model based on its knowledge of the architecture of the ASIC or other hardware element providing forwarding or switching capability to the target device. If the behavior is supported by the target device's architecture, the model may be implemented in a specific manner supported by that architecture and used to control forwarding behavior on the target device.
