Abstract

A fault diagnosis method applied to an optical tunnel network system (OPTUNS) having multiple optical switches and multiple optical fibers connected to the multiple optical switches is disclosed and includes following steps: detecting whether the multiple tunnels of the OPTUNS include a faulty tunnel, where each tunnel respectively passes through multiple component parts; when the faulty tunnel is detected, querying the multiple component parts that are passed through by the tunnels within a certain range with the faulty tunnel; respectively calculating a faulty count of each component part queried, where the faulty count indicates the quantity that the component parts being passed through by the faulty tunnels; and outputting one or more of the component parts that have the faulty count of non-zero.

Dependent claims

A fault diagnosis method for an optical tunnel network system, applied to the optical tunnel network system, wherein the optical tunnel network system comprises a plurality of optical switches and a plurality of optical fibers connected to the plurality of optical switches, and the fault diagnosis method comprises:

a) detecting whether a plurality of tunnels of the optical tunnel network system comprises a faulty tunnel causing data loss, wherein each of the plurality of tunnels respectively passes through a plurality of component parts;
b) when one or more faulty tunnels are detected, querying the plurality of component parts that are passed through by the tunnels within a certain range with the one or more faulty tunnels;
c) respectively calculating a faulty count of each of the plurality of component parts queried, wherein the faulty count indicates a quantity that each of the plurality of component parts being passed through by the one or more faulty tunnels;
and
d) after the step c), outputting one or more of the component parts that have the faulty count of non-zero.
