Optimizing OSPF/IS-IS Weights in a Changing World

Bernard Fortz and Mikkel Thorup

A system of techniques is presented for optimizing OSPF/IS-IS weights for intra-domain routing in a changing world, the goal being to avoid overloaded links. We address predicted periodic changes in traffic as well as problems arising from link failures and emerging hot-spots.
