Policy Definition for Bottom-Up Recovery Scheme in Multilayer Network

For self-healing network, it is essential to deploy coordinated recovery scheme among several layers in multilayer network. By doing root-cause analysis of failures, network recovery function can be performed in the origin layer causing other failures on several layers, and as a result of this recovery function, the damage like service interruption can be prevented or minimized. This paper proposes multilayer network recovery scheme and policies, in which root-cause analysis is integrated with hold-off time of bottom-up recovery scheme.
