Abstract
A technique includes determining a first set of intra-node port weights for a first switch of a first routing node, determining a set of inter-node port weights including a first inter-node port weight for routing traffic to a second routing node, determining a first inter-node weighted port group for the first switch for traffic directed to the second routing node, the first inter-node weighted port group including a first total port weight based on a first intra-node port weight and the first inter-node port weight and which is applied to a first port of the first switch, and a second total port weight based on a second intra-node port weight and the first inter-node port weight and which is applied to the second port of the first switch, and routing traffic to an output port of the first switch based on the first inter-node weighted port group.
