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.
