<p>Provided are a link detection method and device. The method includes: judging whether service overlapping has been configured in a node, if the service overlapping has not been configured, configuring the overlapping of tested wavelengths according to a connection relationship of optical fibres in the node to obtain wavelength paths where the tested wavelengths are located; acquiring the difference between power values at an inlet and an outlet of the wavelength path where each of the tested wavelengths is located; and comparing the difference with a preset threshold, and if the difference is greater than or equal to the threshold, reporting an exception message. The above-mentioned method solves the problem in the prior art that rerouting may fail if line quality changes in a period of time from when performance verification of a rerouting path is manually performed in a commissioning stage to when a failure occurs and rerouting is required.</p> |
