Switching and routing functions may be provided in a data plane of a network switch by having all functions and algorithms needed to handle all related interface, logical and physical, under one interface manager to keep track of bindings between virtual interfaces and logical interfaces, as well as maintain the statuses of ports that belong to the virtual interface and the actual logical ports. When the actual interface goes down, the virtual interface may go down along with it. The bindings may also include definitions. All of these bindings may be located in a single routing information base (RIB) database, eliminating the need for multiple bindings to be kept in various places. Furthermore, a hardware abstraction layer in the control plane can also then be mirrored in the data plane, eliminating the need for the customer to create a layer performing the same tasks.

Methods and apparatus that provide a hardware abstraction layer (HAL) for a robot are disclosed. A HAL can reside as a software layer or as a firmware layer residing between robot control software and underlying robot hardware and/or an operating system for the hardware. The HAL provides a relatively uniform abstract for aggregates of underlying hardware such that the underlying robotic hardware is transparent to perception and control software, i.e., robot control software. This advantageously permits robot control software to be written in a robot-independent manner. Developers of robot control software are then freed from tedious lower level tasks. Portability is another advantage. For example, the HAL efficiently permits robot control software developed for one robot to be ported to another. In one example, the HAL permits the same navigation algorithm to be ported from a wheeled robot and used on a humanoid legged robot.
