Abstract
A method of providing virtual output queue feedback to a number of boards coupled with a switch. A number of virtual queues in the switch and/or in the boards are monitored and, in response to one of these queues reaching a threshold occupancy, a feedback signal is provided to one of the boards, the signal directing that board to alter its rate of transmission to another one of the boards. Each board includes a number of virtual output queues, which may be allocated per port and which may be further allocated on a quality of service level basis.
