A network can break down into several parts. Some parts are local, while others are hosted in a third-party data center. Each of these parts requires some level of management. In this article, we’ll look at the main areas of network management, what is network management & why is it important?…  These areas include Accounting, Performance, Fault management, and Security.


Accounting is one of the key areas in network administration, which deals with granting users access and authority to resources. It can also help in troubleshooting systems that are causing slowdowns. It also collects usage statistics and ensures proper billing. This field is growing and consists of a variety of technologies.

Some businesses need to monitor network utilization to determine their profitability, such as ecommerce firms. Others need to benchmark their network usage against peak periods to determine whether increasing or decreasing network capacity is profitable. Moreover, large enterprises often use shared service organizations to lease resources to different branches and subsidiaries. The use of automation and network performance monitoring can improve the network’s uptime and service availability.

The application that manages this data is called accounting management. It allows network managers to see how users use network resources and bill them accordingly. It also tracks the network’s different types of protocols and traffic patterns. Finally, it compiles usage data and compares them to baseline values to identify potential security threats.


Managing the performance of your network is a critical component of effective network management. By monitoring network performance, you can keep costs down and improve network efficiency. Metrics can monitor network performance, such as packet loss rates, throughput, and response time. These data are supplied to a performance monitoring application and are analyzed to determine what factors may affect network performance. You can apply fault management to detect the problem if performance levels fall below defined thresholds.

Network performance can be measured with metrics and give you an idea of what your network is capable of, but it’s also important to consider the user experience. A network’s QoE (QoE) is the best way to measure network performance from the user’s point of view. This metric can determine whether the network meets end-user expectations.

Fault management

Fault management is the process of identifying and addressing network problems. This process includes monitoring network traffic to detect abnormal behavior. The process should begin with identifying the root cause of the problem.

Fault management is integral to network management and includes monitoring devices, their performance, and their configuration. Monitoring can detect slow-moving errors in a monitored device’s interface, or a slow-growing error rate can be detected with an alarm query and reconfigured to bypass the fault. Fault management is a key area of network management and a growing field.

Fault management refers to a method of detecting faults on a network. Faults manifest as transmission errors, hardware failures, or interface problems and can lead to unexpected downtime, performance degradation, or data loss. Therefore, these faults need to be resolved as quickly as possible to minimize damage and downtime.


Network security consists of monitoring network behavior and controlling network access. This process also involves ensuring that security policies and procedures are followed. Security management tools include network logs and security software. Network security is crucial to the health of your network. Keeping a constant eye on your network can help you detect potential threats and avoid costly downtime.

To protect your network from cyberattacks, IT staff must be vigilant. Their tasks include adhering to compliance requirements, supporting an ever-expanding user matrix, enabling new services, ensuring access controls, and troubleshooting on demand. Additionally, misconfigurations of network devices can expose your network to sophisticated threats. Therefore, network it is crucial for network administrators to implement security policies consistently. One common mistake is deploying thousands of firewall policies that could negatively impact performance.

The complexity of networks increases with the number of connected devices. Hence, network managers must understand the network topology and all device configurations and manage network components accordingly, which is particularly important for networks that contain sensitive data.
