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. |
