摘要： A scalable solution to managing fairness in a congested hierarchical switched system is disclosed. The solution comprises a means for managing fairness during congestion in a hierarchical switched system comprising a first level arbitration system and a second level arbitration system of a stage. The first level arbitration system comprises a plurality of arbitration segments that arbitrate between information flows received from at least one ingress point based upon weights associated with those information flows (or the ingress points). Each arbitration segment determines an aggregate weight from each active ingress point providing the information flows to the segment and forwards a selected information flow along with the aggregate weight (in-band or out-of-band) to the second level arbitration system. The second level arbitration system then arbitrates between information flows received from the arbitration segments of the first level arbitration system based upon the aggregate weights received along with those information flows. The second level arbitration system then forwards a selected information flow to an egress point of the stage. The stage may, for example, comprise a portion of a switch, a switch, or a switch network.

摘要： A switching device comprises at least two base racks, each base rack including a switch card in communication with a line card across a backplane, the line card having at least an external port. The at least two base racks are coupled such that the switch cards of each are linked. A method for switching a packet comprises introducing the packet into an external port on a first base rack, transmitting the packet from a first cascade port on the first base rack to a second cascade port on a second base rack, and sending the packet out of the second base rack through a second external port.

摘要： A scalable solution to managing congestion in a network is disclosed. In one implementation, such a solution comprises a means for managing traffic including at least one flow monitor and a plurality of flow control regulators that together manage congestion within a network. Each of the flow control regulators monitor traffic at a corresponding ingress point and determine a state of the ingress point corresponding to the traffic monitored at the ingress point. Each flow control regulators forward the state (or information representative of the state) to the flow monitor. The flow monitor detects congestion based upon the states of the flow control regulators and, in the event of congestion, determines a target bandwidth for the ingress points. The flow monitor provides a control signal to at least one of the flow control regulators, and at least one of the flow control regulators control flows at its corresponding ingress point based upon the control signal received from the flow monitor.
