Abstract
A switching network includes an upper tier including a master switch and a lower tier including a plurality of lower tier entities. The master switch includes a plurality of ports each coupled to a respective one of the plurality of lower tier entities. Each of the plurality of ports includes a plurality of virtual ports each corresponding to a respective one of a plurality of remote physical interfaces (RPIs) at the lower tier entity coupled to that port. Each of the plurality of ports also includes a receive interface that, responsive to receipt of data traffic from a particular lower tier entity among the plurality of lower tier entities, queues the data traffic to the virtual port among the plurality of virtual ports that corresponds to the RPI on the particular lower tier entity that was the source of the data traffic. The master switch further includes a switch controller that switches data traffic from the virtual port to an egress port among the plurality of ports from which the data traffic is forwarded.
