Fault management in network management – what you need to know

The interconnected world of today relies heavily on telecommunication. Stability and reliability of network is of a great importance. However, as the network constantly grows not only in scale but also in complexity. This massive growth increases the possibility of potential issues. More and more telecommunication companies needed to work out some kind of network fault management system with the OSS fault management on the top. What is fault management in network management? How to ensure seamless network performance? Check it out?

Fault management in network management – what is this?

As businesses depend on the network, its performance needs to be flawless. As nothing is perfect, faults happen. But the best telecoms know how to handle problems quickly and effectively. That is why, they implement advanced network fault management and fault monitoring. Fault management is one of the most important aspects of network management. It consists of the fault diagnosis, isolation, and fault resolution of issues and faults connected with the telecommunications network. The root cause of the network faults can be different – from software glitches, hardware malfunctions, to other external factors. Prompt fault detection and problem resolution is essential to minimize downtime and ensure the highest quality service delivery to customers.

Alarm Monitoring in Telecom: how to enhance network surveillance?

Sophisticated network fault management tools leverage advanced automation and analytics to quickly react on all abnormalities to solve all the issues.

Alarm monitoring in telecom

Alarm monitoring is an important factor in fault management in telecom. In the modern telecommunication networks, there is a vast amount of alarms generated every minute. They can be related to various events, for example device malfunctions, network failures, security breaches, traffic congestion. The alarms enable to distinguish the reason of the alarm and severity of the problem in order to assure swift response to network faults.

Alarm correlation in fault management

It is not uncommon, especially in big networks, that multiple alarms are triggered in the same moment. It can lead to a tremendous amount of notifications to handle simultaneously. That is why, alarm correlation is vital in the management process. Alarm correlation means identification and grouping of the alarms (alarm management). Then, the redundant alerts are filtered out, so that the network administrators are provided with a more relevant and concise overview of the issues to be taken care of. Automatic alarm management prevents alarm floods, so the critical issues can be handled more effectively.

What is a rule-based alarm management?

Rule-based fault management is one of the automatic fault management systems. This management tool depends on rules and thresholds, which help to manage alarms. The rules can be set up basing on their status like alarm type, location, severity. Using this approach, the network administrators can handle the critical issues are handled promptly. This rule-based approach enhances fault resolution and ensures that resources are directed efficiently.

Automatic Fault Management: a true game changer

Traditionally, the network fault management has been held manually. In some cases, manual intervention has turned out to be time-consuming and prone to errors. The invention of the automatic network fault management systems simplified the process, making it easier to address the network faults quickly and more accurate. These network management software with powerful algorithms empowered by artificial intelligence can detect anomalies in the network data, allowing active fault management.
