Abstract
Abstract—In this work, we show an algorithm to analyze the information of the alarms emitted by the components of an optical network, in the presence of a fault, aiming to find which network component is causing the failure. The algorithm proposed, named Correlated Fault location Algorithm, CFLA, uses the alarms ’ correlation in order to reduce the list of suspected components shown to the network operators. The CFLA is sufficiently robust to work with false alarms, lost alarms and components that do not emit alarms when fail. The algorithm is described and simulated. The results of the simulations are compared to those obtained using another algorithm found in the literature.
