Summary:Methods of routing and switching a packet from an incoming link to an outgoing link of a router. In one example, the method includes assigning a destination queue to the packet, determining if the router is implemented in a scaled-down configuration, remapping the destination queue to one or more remapped destination queues, and storing the packet in the one or more remapped destination queues. In one embodiment, the method may also include requesting a packet from the destination queue, translating the request to the remapped destination queue, and transmitting the packet from the remapped destination queue.
