  • Patent number: 9602439
    Abstract: In some embodiments, an apparatus includes a switch fabric having at least a first switch stage and a second switch stage, an edge device operatively coupled to the switch fabric and a management module. The edge device is configured to send a first portion of a data stream to the switch fabric such that the first portion of the data stream is received at a queue of the second switch stage of the switch fabric via the first switch stage of the switch fabric. The management module is configured to send a flow control signal configured to trigger the edge device to suspend transmission of a second portion of the data stream when a congestion level of the queue of the second switch stage of the switch fabric satisfies a condition in response to the first portion of the data stream being received at the queue.
