METHOD AND DEVICE FOR DISCRIMINATING NETWORK FAULT

摘要

PROBLEM TO BE SOLVED: To discriminate the degree of a network fault when the network fault occurs. SOLUTION: A monitoring part detects information of a fault that occurs in a network 100 and digitizes the information, and a data comparison processing part 103 compares the digitized network fault information with a fault sign threshold 104a and a fault detection threshold 104b. As a result, a fault sign is outputted as an alarm when the digitized network fault information surpasses the fault sign threshold, and furthermore, a fault occurrence is outputted as an alarm when the digitized network fault information surpasses the fault detection threshold.
