More Information
Summary:A method and device for detecting shared risk link groups is disclosed. The method comprises injecting a probe beam, respectively, into a first test link and a second test link. The method further includes recording, respectively, a first curve of a time-varying first power corresponding to the first backlight and a second curve of a time-varying second power corresponding to the second backlight; calculating a resemblance value for the first curve and the second curve; and judging, based on the resemblance value, whether the first test link and the second test link are located in the same shared risk link group. The method and device for detecting shared risk link groups provided by embodiments of the present invention detect by testing a power characteristic of backlight of a probe beam in test links and, based on that one-dimensional power characteristic, judge whether the test links are in the same shared risk link group, which are simpler in application than those in the prior art.
