Risk identification method and related device

Abstract

The invention discloses a risk identification method and a related device, which are applied to the field of optical networks, and ensure that a failed optical fiber is accurately positioned subsequently by judging the credibility of optical fiber data collected from different detection points, so that the service recovery time is effectively shortened. Verification is carried out from the optical fiber data, manual regular inspection and additional hardware are not needed, and the risk identification efficiency is effectively improved. The method comprises: receiving any two optical fiber data sent by a first transmission device or a second transmission device, first optical fiber data in the any two optical fiber data indicating a first optical fiber feature of a first optical fiber detected at a first detection point; the second optical fiber data indicates a second optical fiber feature of the second optical fiber detected at the second detection point or a third optical fiber feature of the first optical fiber, then making a risk judgment based on a first correlation coefficient between the first optical fiber data and the second optical fiber data, and generating alarm information when the first correlation coefficient is smaller than a preset safety threshold.

Description

technical field [0001] The present invention relates to the technical field of optical networks, in particular to a risk identification method and related devices. Background technique [0002] As a large-capacity, low-latency communication medium, optical fiber plays an indispensable role in optical network communication. With the continuous expansion of the network scale and the gradual increase in the number of devices, the connection between devices and devices through optical fibers has gradually formed a dense and complex situation. Generally speaking, if the physical connection of optical fibers between multiple devices is incorrect, or the logical connection of optical fibers configured in the controller is inconsistent with the physical connection, it is easy for the network management device to fail to monitor and locate the faulty device in time. fiber, and miss the opportunity to repair the faulty fiber, thereby affecting the service recovery time.
