RECOVERY FROM MULTIPLE FAULTS IN A COMMUNICATIONS NETWORK

摘要

A method of recovery from multiple faults in a communications network comprising: a. receiving an alarm signal from each of a plurality of faults in the communications network, each alarm signal comprising a respective alarm descriptor; b. for each alarm signal: i. analysing the respective alarm descriptor to identify a possible root cause of the alarm signal; ii. providing a root cause metric for the identified possible root cause, the metric being indicative of a difficulty of repairing the respective fault; iii determining a service impact caused to the communications network by the respective fault; iv. providing a service impact metric indicative of the service impact; v. combining the root cause metric and the service impact metric to generate an alarm metric; c. ranking the alarm signals in dependence on their respective alarm metrics; and d. causing the fault having the highest ranked alarm metric to be repaired first.

1. A method of recovery from multiple faults in a communications network, the method comprising:
a. receiving an alarm signal from each of a plurality of faults in the communications network, each alarm signal comprising a respective alarm descriptor; b. for each alarm signal received:
i. analyzing the respective alarm descriptor to identify a possible root cause of the alarm signal;ii. providing a root cause metric for the identified possible root cause, the metric being indicative of a difficulty of repairing the respective fault;iii. determining a service impact caused to the communications network by the respective fault;iv. providing a service impact metric indicative of the service impact; andv. combining the root cause metric and the service impact metric to generate an alarm metric; c. ranking the alarm signals in dependence on their respective alarm metrics; and d. causing the fault having the highest ranked alarm metric to be repaired first.
