This paper proposes a novel recovery mechanism from large-scale network failures caused by earthquakes, terrorist attacks, large-scale power outages and software bugs.
Our method, which takes advantage of overlay networking technologies, pre-calculates multiple routing configurations to prevent possible simultaneous network failures and selects one configuration immediately after detecting the failures.
Through numerical calculation results using actual AS-level topology, we show that our proactive method improves network reachability from 87% to 98%, while keeping the path length sufficiently short, when up to 8% of the nodes in a network are down simultaneously.
In addition, we present ratio of traffic failure(s) case to traffic in failure-free case and discussion about it. |
