Abstract:
1. A network router to route Internet protocol (IP) data packets comprising: a plurality of trunk ports, including a composite port of plural ports to plural trunks that serve as a composite trunk to a common destination; a routing fabric configured to transfer an IP data packet between the plurality of trunk ports; a routing table configured to use a destination IP address of the IP data packet to route the IP data packet by determining a composite output trunk; and an output port selector configured to use the determined composite output trunk and information stored in a packet descriptor of the IP data packet to select an individual output port of the composite output trunk for the IP data packet, the output port selector comprising a forwarding table having plural entries to each individual output port and dynamically balancing load by weighting a number of entries to each individual output port, each entry in the forwarding table being dynamically rewritable to a different individual output port.
