Abstract: In some embodiments, an apparatus includes a flow control module configured to receive a first data packet from an output queue of a stage of a multi-stage switch at a first rate when an available capacity of the output queue crosses a first threshold. The flow control module is configured to receive a second data packet from the output queue of the stage of the multi-stage switch at a second rate when the available capacity of the output queue crosses a second threshold. The flow control module configured to send a flow control signal to an edge device of the multi-stage switch from which the first data packet or the second data packet entered the multi-stage switch.

Abstract: In some embodiments, an apparatus comprises a switch from a set of switches associated with a stage of a multi-stage switch fabric. The switch is configured to receive a data packet having a destination address of a destination device from a source device, and then store the data packet in a queue of the switch. The switch is configured to define a message based on the queue having an available capacity less than a threshold, and include a congestion root indicator in the message if the switch is a congestion root. The switch is then configured to send the message to the source device such that the source device sends another data packet having the destination address of the destination device to another switch from the set of switches and not to the previous switch if the message includes the congestion root indicator.
