In accordance with embodiments of the present disclosure, a method may include sorting potential optical layer link failures in a network in an increasing order of failed traffic amount. The method may further include, for each potential optical link failure in increasing order of failed traffic amount: determining the additional higher layer link capacity required on existing higher layer links associated with the potential optical link failure using higher layer restoration of the potential optical link failure; determining the additional optical layer capacity required for restoring the existing higher layer links associated with the potential optical link failure using optical layer restoration; and selecting one of the higher layer and the optical layer as a restoration layer for restoration of the existing higher layer links associated with the potential optical link failure based on the determined additional higher layer link capacity and the determined additional optical layer capacity. |
