Quickly recovering IP networks from failures is critical to enhancing Internet robustness and availability. Due to their serious impact on network routing, large-scale failures have received increasing attention in recent years. We propose an approach called Reactive Two-phase Rerouting (RTR) for intra-domain routing to quickly recover from large-scale failures with the shortest recovery paths. To recover a failed routing path, RTR first forwards packets around the failure area to collect… CONTINUE READING
