ABSTRACT:
A method, apparatus, and computer-readable media for a first stack unit in a stackable network device comprises a plurality of the stack units interconnected by a plurality of stacking links, the first stack unit comprising a control plane processor to receive, from a third stack unit, a path message that identifies a second stack unit; wherein the control plane processor transmits the path message to the second stack unit; wherein the control plane processor receives, from the second stack unit, a reserve message; wherein the reserve messages identifies a requested resources for a planned data flow within the stackable network device, wherein the planned data flow has a quality of service; a plurality of ports to receive and transmit packets of data; and a forwarding engine to transfer the packets of data between the ports in accordance with the control plane processor.
