  • End-to-end congestion control in a Fibre Channel network
    Patent number: 7734808
    Abstract: Methods and devices are provided for controlling congestion in a network such as a Fibre Channel network. According to some implementations, a node within a network fabric detects congestion caused by an edge device outside of the fabric and notifies the edge device of the congestion. The edge device applies a congestion reaction mechanism in response to the notification. In some implementations, the congestion reaction mechanism is applied on a per-exchange basis, in order to mitigate congestion caused by a particular operation.
