Fault management system remains as a critical component of any Network Management System present in the telecom industry. The final goal for any telecom service provider is to develop a high availability of service to its customers. For any telecom operator there’ll this module Alarm system or even known as Fault Management system to handle the faults in the system. The faults can be ranging anywhere from a hardware fault, a security breach, a software error or anything which can be a possible threat to the high availability of the service. With the number of customers increasing daily, the network in telecom graphs form like an evolving graph. Thus, the complexity of the telecom network also increases with the increase in nodes.

Considering the software faults apart, the amount of hardware faults is increasing in an alarming rate. This is because most of the operators build the hardware infrastructure in a hybrid fashion i.e., with different hardware from different providers. Many of these hardware faults can lead to denial of service to the customers and are of critical severity. As for the service provider, one hardware fault can impact connected nodes in the network and might also bring down a huge part of it. This paper deals with a solution from a service provider’s point of view, that when multiple faults are reported by the fault management system, it should prioritize the faults in the order that they need to be resolved so that the loss incurred is minimized.
