Abstract
A resilient load balancing method uses fixed paths and a fixed path-splitting strategy to enable ingress routers to efficiently reroute traffic after a failure. An off-line management system computes a set of fixed paths and a set of splitting ratios for routing demand from ingress routers to egress routers, with sufficient capacity to meet demands under each failure scenario. That data is then used by the ingress router to reroute demand after observing a failure.
