A network management system can be divided into

A Network Management System (NMS) can be often divided into five functional areas, commonly referred to by the FCAPS model, which stands for:

1. Fault Management: This involves detecting, isolating, diagnosing, and correcting network problems to keep the network running effectively. It includes monitoring and notifying the network administrator of issues like link failures, malfunctioning devices, or other problematic issues that might affect the network’s performance.

2. Configuration Management: This area deals with the setup of network devices and software to operate with optimal performance and security settings. It includes tasks like configuring new devices, modifying settings on existing devices, tracking configuration changes, and ensuring that the settings applied are within the policies defined for the network.

3. Accounting Management (sometimes referred to as Administration Management): This focuses on tracking and billing for the use of network resources. It can involve measuring resource utilization by users, departments, or specific applications, and possibly implementing chargeback mechanisms to allocate network operation costs to those entities that generate the most traffic or require special resources.

4. Performance Management: This involves monitoring and measuring network performance on a continuous basis to ensure that network performance remains at acceptable levels. It includes the collection of data to evaluate parameters such as network throughput, latency, packet loss, and availability. Performance management helps in identifying trends that may indicate future problems and offers opportunities to optimize resources.

5. Security Management: This focuses on protecting the network and its resources from unauthorized access,
