Abstract
A method for routing a packet received in a packet router is taught, the method comprising the steps of selecting a logical interface having multiple physical ports as a destination for the packet, processing any one or more addresses or labels of the packet and other packets received by a common function, producing thereby results unique to the packets in which the addresses and labels processed differ, (c) mapping the physical ports at the destination to the unique results produced by processing the addresses or labels of packets, and (d) routing the data packet according to the mapping. Weighting is applied to physical ports in the mapping, the weighting reflecting different transmission capacities of the ports. Apparatus for practicing the invention is taught as well.
