Abstract
A monitor () receives a returned response message, and stores the state of the link directed to the NE that returned the message as a successful transmission, and then repeats the same operation at arbitrary intervals. When the monitor can not receive the response message after placing a certain interval, it stores the link as an unsuccessful transmission. At this point, if all the links for a particular NE are in the unsuccessful state, the monitor informs an NMS () of a fault in that NE. If the NE truly has the NE fault, other NEs that also have the links to that fault NE inform the NMS of the fault. Thereby the NMS itself does not need to do the monitoring. The NMS only collates fault information with topology information stored in a topology information storage () and can judge that a particular NE is out of communication and control.
