Error detection in communication systems

摘要

The invention is directed to a method for determining the impact on a network of a fault in the network, comprising the steps of constructing a layered topological model of the network according to a predetermined protocol; receiving an indication of an erroneous event at a point in the network; and modelling the impact on the network and its services resulting from said event by navigating the topological model. The invention is also directed to a human user interface and a computer program adapted to perform this method and a network comprising means to locate a fault in the network.
