Abstract
Switches for performing packet switching and associated methods are provided. An example switch includes an ingress port for receiving a packet. The switch includes a plurality of egress ports for discharging the packet from the switch. The switch includes a plurality of egress queues with each egress queue associated with one of the plurality of egress ports. The switch includes a control plane configured to determine a descriptor associated with a packet, determine a first egress port from which to discharge the at least one packet and to transmit the descriptor to an egress queue associated with the first egress port. The switch includes a descriptor crossbar configured to transmit the descriptor from the egress queue to a second egress port of the plurality of egress ports. The switch includes a packet crossbar configured to transmit the at least one packet from the ingress port to the second egress port.
