Patent ID: 8705369

Claim:
A method, comprising: receiving, by a computing device, first routing information including multiple routing pairs and current weights for each of the multiple routing pairs; receiving, by the computing device, second routing information including the multiple routing pairs and proposed new weights for each of the multiple routing pairs; ranking, by the computing device, the first routing information based on particular criteria; ranking, by the computing device, the second routing information based on the particular criteria; comparing, by the computing device, a rank order between a first routing pair of the multiple routing pairs and a second routing pair of the multiple routing pairs using the first routing information and a rank order between the first routing pair and the second routing pair using the second routing information; identifying, by the computing device, a change from the rank order between the first routing pair and the second routing pair using the first routing information to the rank order between the first routing pair and the second routing pair using the second routing information; and generating, by the computing device, a data structure that indicates the change in the rank order.
