ABSTRACT:
A method, apparatus, and computer program product for balancing transmission unit traffic over network links, including disposing transmission units into flows; grouping flows into first flow lists, each corresponding to a selected network link; determining a traffic metric representative of a traffic load on the selected network link; responsive to the traffic metric, regrouping flows into second flow lists corresponding to the selected network link, the regrouping balancing the transmission unit traffic among the network links; and transmitting the respective second flow list over the respective selected network link. The invention also can include a method for transmitting transmission units through a network, including receiving a transmission unit from a transmission unit source; classifying the transmission unit according to a predetermined flow characteristic; selecting a preselected network link over which the transmission unit is to be transmitted; and transmitting the transmission unit over the preselected network link.
