What are the functions of network management? There are many different functions that network administrators are responsible for. These functions include configuration, fault, performance, and security management. For example, performance management monitors and evaluates network resources, while security management protects network objects from harm. Finally, accounting management is concerned with maintaining a record of network resources. All these functions are supported by an information system that includes an operating system, a database platform, a communications protocol, and a user interface.
Configuration management in network administration is a process that allows network administrators to control network devices. This is particularly useful for those who need to replace or reconfigure devices, such as servers, quickly. By using configuration management, administrators can show compliance with security standards. Moreover, configuration management software helps administrators detect unauthorized changes to network devices and can even automate correcting those changes. Various configuration management tools are available online and in hardware stores.
Managing computer network configurations has evolved significantly from the days of the manual change. Earlier, network configuration management required a lot of time and effort. Besides needing a manual process, it also introduced many configuration errors and lacked rollback options. In network management, configuration management tools help network administrators monitor and organize information about various network devices, such as routers and switches. They are also responsible for the setup and maintenance of installed firmware.
Accounting in network management refers to measuring and reporting system and network utilization parameters. It forms a vital part of service level agreements (SLAs), as it provides a practical means of defining obligations and ensuring clear consequences when behavior falls outside SLAs. These data are collected through NMSs, which deploy probes on access and edge routers to monitor traffic flow between sources and destinations. The data collected can be interpreted in many ways, from identifying abnormal patterns to predicting the performance of future networks.
While performance and accounting management are closely related, there is a crucial distinction between them. Accounting management aims to determine and understand statistical trends, while performance management focuses on billing and tagging usage data to actual users. Accounting management, on the other hand, sets stricter data collection requirements. Data loss in performance management can lead to a reduction in revenue. Therefore, accounting management is not the primary goal of network management.
Modern IT infrastructures are becoming more complex than ever. Networks are composed of numerous components that contribute to productivity, network performance, and positive user experience. Unfortunately, this complexity makes maintaining comprehensive visibility of network performance difficult. In addition, as technology stacks have expanded into third-party SaaS applications and have grown in density locally, performance problems are often difficult to isolate and track down. Fortunately, performance management solutions are available to help address the growing complexity of today’s networks.
Network performance management (NPM) is a collection of methods and processes for ensuring optimal performance levels in network infrastructures. It routinely monitors service levels, bandwidth usage, network node outages, and packet loss. Network performance monitoring tools can pinpoint problems and mitigate them before they harm end-users by reviewing and analyzing performance metrics on a granular level. In addition, NPM tools analyze data using artificial intelligence to help IT determine what is wrong and how to fix it.

Security management involves the control of access and sensitive information on network devices. It includes the use of passwords and encryption to protect sensitive information. Many methods exist for encryption, including public and private keys. These methods can reduce the risk of data breaches by preventing unauthorized users from accessing sensitive information. These practices have several benefits, including reducing the cost of non-compliance and time spent manually managing security. In addition, by ensuring the protection of sensitive data, network security management can help organizations to comply with various regulatory requirements.
Security management is essential for a company’s network, and an effective security management program can help administrators manage the web from a single location. Security management solutions can automate device configuration, enforce global policies, view firewall traffic, and generate reports. Moreover, they give administrators a single management point for physical and virtual systems. By automating these processes, administrators can save time while reducing risk and improving efficiency. Here are three key benefits of network security management.
Network monitoring refers to the periodic check of network components. It should be conducted as often as possible and at regular intervals to determine the network’s health. This type of monitoring may be necessary for servers, routers, switches, and printers, as they do not require immediate attention. You should determine monitoring intervals component by component. Listed below are the different types of monitoring that may be required. In addition, listed below are some of the most common types of monitoring and how they can benefit your network.
Depending on the number of devices and events, a sound monitoring system may be more complicated than a small network. In addition, large networks need different monitoring systems than small enterprises, and complex multi-cloud environments need more sophisticated techniques. Finally, network monitoring must consider the entire network, as it is a complex system, and you must monitor its performance and security. Otherwise, outages may go unnoticed.
Network troubleshooting involves identifying and diagnosing a wide range of issues in a network. These issues can be caused by changes in the network, software updates, or cable issues. Sometimes there are several problems in one network; if you’ve already troubleshot one problem and discovered another, it may be easier to find the culprit and fix it at once. For this reason, troubleshooting in network management should begin with the most straightforward causes.
To successfully troubleshoot a network issue, you must collect information. You can gather this information from users and network data. The quality and efficiency with which this information is collected can determine whether or not it will help you fix the problem. This book covers the various tools available for gathering data and how to use them effectively. It focuses on the first crucial step: information gathering. This includes examining network data and user feedback.
