摘要：A mechanism is disclosed for enabling load balancing to be achieved in anetwork. In one implementation, load balancing is implemented on a “per flow” basis.
At the time that a new flow starts, a path is selected. Packets associated with the flow arethereafter sent along that particular path. As the packets associated with the flow areforwarded along the particular path, a congestion metric is determined for the particularpath as well as for a set of one or more other paths. Based at least partially upon thecongestion metrics, a determination is made as to whether the flow should be moved. Ifso, then the flow is moved to an alternate path. By determining the congestion metricsfor the multiple paths, and by moving the flow in response, it is possible to adapt tochanging traffic conditions to keep the loads on the paths relatively balanced.
