Abstract
Methods and apparatus for routing mixed cast requests through a Clos-like network are disclosed. According to one aspect of the present invention, a method for processing a routing request within a network system includes computing costs associated with input links between a center stage and an input stage and computing costs associated with output links between the center stage and an output stage. The method also includes comparing the costs associated with the input links and the costs associated with the output links to identify a first input link, a first output link, and a second output link. The first output link is associated with a first center stage node and the second output link is associated with a second center stage node. The request is routed using the first input link, the first output link, and the second output link.
