    • The invention relates to a method for fault analysis in a multi-layer network. The method includes receiving (210) a first set of performance measurements occurring in response to the fault and representing at least a first and a second layer in a multi-layer communications network. A probable set of network elements affected by the fault are localized (220). The type of fault is inferred (230) from one or more symptoms in the performance measurements. The root cause of the failure is determined (240) from a combination of the information on probable set of network elements and inferred type of fault. The invention also relates to an arrangement in a network management node for carrying out the inventive method. The arrangement includes a root cause analyzer (320) to detect affected network elements and fault type upon network failure, wherein affected network elements are determined in a spatial localization unit (320) and the fault type is determined in a fault type inference unit (350).
