ABSTRACT:
A switching system includes a switch fabric that includes groups of buffers for each port interface device that communicates with external communication devices through an Ethernet plane. The port interface device is formed to receive congestion ratings reflecting buffer usage within the switch fabric for each device coupled to transmit and receive packets through the switching fabric and to determine whether to route to the switching fabric or drop the packet based upon the congestion rating of the destination device and upon a quality of service rating for the packet.
