  • Publication number: 20110320857
    Abstract: A bottom-up (or upward) multilayer network recovery method and apparatus based on a root-cause analysis are disclosed to quickly and accurately perform a recovery operation. The bottom-up multilayer network recovery method based on a root-cause analysis includes: simultaneously counting, by a fault detection layer, a root-cause analysis (RA) time and a hold-off (HO) time, upon detecting an occurrence of a fault; performing, by the fault detection layer, a root-cause analysis during the RA time to recognize a layer in which a root-cause has occurred; when the root-cause has occurred in the fault detection layer, immediately recovering the fault by the fault detection layer, and when a root-cause has occurrence in a lower layer, waiting for the HO time until such time as the lower layer can recover the fault; and when the fault has not been recovered even after the HO time has lapsed, recovering the fault by the fault detection layer.
