Abstract
In-band flow control data may be received from a switch fabric at a first network processor. The received in-band flow control data may be transmitted to a second network processor using a flow control bus. The second network processor may determine which receive queues in the switch fabric exceed a predetermined overflow threshold based on the in-band flow control data. The second processor may transmit data to the receive queues in the switch fabric determined not to exceed the predetermined overflow threshold.
