What are the five major functions of network management?

The five major functions of network management are: 1. Fault management; 2. Configuration management; 3. Billing management; 4. Performance management; 5. Security management.

# Network management is the most important means to ensure the reliable operation of the network. The network management system can provide rich, professional and customized network management functions according to user needs.

The network management function enables comprehensive monitoring and management of the network. With the expansion of network scale and the diversification and complexity of application technologies and products in the network, network owners and maintenance personnel are increasingly looking forward to high-end, professional and personalized network management functions.

Five major functions of network management

1. Fault Management

Fault Management is one of the most basic functions in network management. When a component in the network fails, the network manager must quickly find the fault and eliminate it in a timely manner.

Network fault management includes fault detection, isolation and correction, including the following typical functions:

• Maintain and check error logs

• Receive and respond to error detection reports

• Track and identify errors

• Perform diagnostic tests

• Correction of errors

2. Configuration Management

Configuration management is responsible for initializing the network and configuring the network so that It provides network services. Configuration management is a set of related functions necessary to identify, define, control and monitor the objects that make up a communication network, in order to achieve a specific function or to optimize network performance. This includes:

• Setting parameters related to routing operations in the open system

• Management of managed objects and managed object group names

• Initialize or close managed objects

• Collect information about the current status of the system as required

• Get the system Important change information

• Change system configuration

3. Accounting Management

Accounting management records the use of network resources, with the purpose of controlling and monitoring the costs and costs of network operations. Including the following functions:

• The billing management function can estimate the fees and costs that users may need to use network resources, as well as the resources that have been used.

• The network administrator can set the maximum fee that users can use, thereby controlling users' excessive occupation and use of network resources.

• When a user needs to use resources in multiple networks for a communication purpose, the total cost can be calculated through the billing management function.

4. Performance Management (Performance Management)

Performance management is used to evaluate system performance such as the operating status of system resources and communication efficiency. Its capabilities include monitoring and analyzing the performance mechanisms of managed networks and the services they provide. The results of the performance analysis may trigger a diagnostic test procedure or reconfigure the network to maintain network performance. Performance management collects and analyzes data and information about the current status of the managed network and maintains and analyzes performance logs.

Typical functions include:

• Collect statistical information

• ##Maintain and check system status logs

• Determining the performance of a system under natural and artificial conditions

• The operation of changing the system operating mode for system performance management

5. Security Management

Network security management includes the management of authorization mechanisms, access control, encryption and encryption keywords, in addition to maintaining and checking security logs. Includes the following functions:

• Create, delete, and control security services and mechanisms

• Distribution of security-related information

• Report of security-related events
