Abstract
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.
