Fault Management

Abstract

No system is infallible. Detection of recovery from and damage limitation of failures are needed for every mission-critical business function. The network is a mission-critical component of the telecom business as it is critical to the revenue and reputation of the service provider. Understanding, monitoring and managing individual NEs may not be hard, but as the network increases in size and complexity, understanding the relationship between the various elements, monitoring and managing their interrelationship and the problems that arise due to their interrelationship can become challenging. Service impact of faults also becomes more complex as the network and the services offered become more complex. Owing to cost and the possibility of human error, it is not practical to deploy an army of personnel to administer a large network. Fault management OSS systems are currently the only economical way to achieve network-wide fault monitoring.
