What are fault alarms?
An alarm is a persistent indication of a fault that clears only when the triggering condition has been resolved. A current list of problems occurring on the network component is often kept in the form of an active alarm list such as is defined in RFC 3877, the Alarm MIB.
What is fault notification?
Fault Notification The time between initiation of a fault notification message (e.g Fault Indication Signal (FIS)) by the LSR detecting the fault and the time at which the Path Switch LSR (PSL) begins the recovery operation.
What is fault detection process?
According to generally accepted terminology, fault detection is a task to determine or indicate faults in a process or system and then the faulty process or variable should be isolated because isolating faults gives additional useful information about the faults, e.g., root cause of a fault [5,41].
What is fault in network?
We can define network faults as events that interfere in the correct functioning of the network and therefore, reduce its performance. The most common faults include hardware issues, cables, wireless interference, change of port status, broadband saturation, or even worse, loss of connectivity.
What are fault management tools?
alarms that notify administrators and users of impending and actual malfunctions; tracing the locations of potential and actual malfunctions; automatic correction of potential problem-causing conditions; automatic resolution of actual malfunctions; and.
What is the purpose of fault management?
Fault management is the component of network management concerned with detecting, isolating and resolving problems. Properly implemented, network fault management can keep connectivity, applications and services running at an optimum level, provide fault tolerance and minimize downtime.
Why is fault management necessary?
Network fault management is necessary, because maintaining and guaranteeing network continuity has become essential. A properly managed fault system offers many positive benefits; a properly managed network guarantees availability, minimizing downtime and early detection of faults.
What are the tools for fault detection?

What is fault problem?
A “fault” is another word for a problem. A “root cause” fault is a fundamental, underlying problem that may lead to other problems and observable symptoms. (It might not be directly observable). A root cause is also generally associated with procedures for repair.
