Method and device for predicting and determining failure

摘要

A method and a device for predicting and determining a failure include a signal monitor that monitors the signal quality of each link, a signal quality prediction section that predicts future signal quality by using given forecast information and information on the monitored signal quality, and a failure prediction determination section that, depending on a degree of deterioration of the predicted signal quality with respect to a link, determines to bypass the link or to lower the symbol rate of the link.

主权项

1. A device for predicting and determining a failure, wherein the device is provided to a node of a communication network, the device comprising:
a signal monitor for monitoring signal quality of each of links connected to the node; a signal quality prediction section for predicting future signal quality of a link by using given forecast information and information on the signal quality monitored with respect to the link; and a determination section for determining to bypass the link or to lower a symbol rate of the link, depending on a degree of a deterioration of the predicted signal quality with respect to the link; an accumulation section for accumulating signal quality information concerning failures occurring in each of the links in a past, wherein the determination section calculates a differential between the predicted signal quality information and a piece of the accumulated signal quality information that is closest to the predicted signal quality information among the accumulated signal quality information, and depending on a size of the differential, determines to bypass the link or to lower the symbol rate.
