Five basic functions of network management functions
In the actual network management process, network management has a very wide range of functions, including many aspects.
The five main functions of network management are:Fault management is one of the most basic functions in network management. When a component of the network fails, the network manager must quickly find the fault and promptly remove it.
Network fault management includes fault detection, isolation and correction of three aspects, including the following typical functions: maintain and check error logs to receive error detection reports and respond to tracking, identifying errors to perform diagnostic tests to correct the error performance management is used to evaluate the operation of the system’s resources and the efficiency of the communication and other system performance. Its capabilities include mechanisms to monitor and analyze the performance of the managed network and the services it provides. The results of performance analysis may trigger a diagnostic testing process or reconfiguration of the network to maintain network performance. Performance management collects and analyzes data information about the current condition of the managed network and maintains and analyzes performance logs.
Typical functions include: collecting statistical information maintaining and examining system status logs determining system performance under natural and artificial conditions changing system operating modes for system performance management operations general switch VLAN configuration is implemented directly on the switch, while configuring VLANs between switches through the network management system makes VLAN configuration easier and faster.
Network Management Functions of Network Management System
Network management is the most important means to ensure the reliable operation of the network. Network administrators through the network management system for comprehensive monitoring of the network. A well-functioning network management system mainly has the following major functions.
1. display network topology map
Network management system first of all have networked devices auto-discovery function, and through the use of IP and IPX network color-coded hierarchical view, to establish the layout of the network image map.
2. Port status monitoring and analysis
Monitoring and analyzing the port status of network devices is a key function of any network management system. Through the network management system, network administrators can easily get extended data on port status, bandwidth utilization, traffic statistics, protocol information and other network efficacy statistics.
3. Graphical analysis of network performance and status
Any network management system has the ability to analyze flexible curves and graphs, enabling network managers to quickly grasp the state of the network operation and quickly record the relevant data, and at the same time can be analyzed in the form of file output or for other data analysis tools such as spreadsheets.
4. Troubleshooting and Alarm
Troubleshooting and alarm is one of the important management functions of the network management system. Network management system configured with a large number of network management software, the entire network status can be fast, comprehensive, intelligent detection, not only can judge the network of all the equipment connected or disconnected, but also through the detection of the distribution of traffic throughout the network, to determine the location of the bottleneck of the network communication, in order to adjust the distribution of network equipment in a timely manner to adjust the network equipment, adjusting the network device’s working time, so that the network works in the best The network can work in the optimal state. Diagnosis of faults in the network is done through threshold management of network state parameters, which generates an alarm or event notification for a wide range of network devices. Event filters allow events to be compressed into useful information to accelerate troubleshooting.
5. Simplified network device management
Simplified management of switches, routers, and other devices in a network management system environment.
6. With the ability to configure VLAN
General switch VLAN configuration directly on the switch, and through the network management system to configure VLANs between switches, so that the configuration of VLANs simpler and faster.
With the continuous development of network technology, the continuous improvement of the application level, the network management puts forward higher requirements, the network management system’s function is also constantly enhanced, network management concepts, technologies and methods are also constantly innovative. In short, through the network management system, the ultimate goal is to be able to improve the availability and reliability of the network, so as to improve the overall efficiency of network operation and reduce management costs.
What are the five functions of network management?
ISO defines five major functions of network management in the ISO/IEC7498-4 document, which is widely accepted.
The five functions are:
1. Fault management (faultmanagement) Fault management is one of the most basic functions in network management. Users want a reliable computer network, when a problem occurs in one of the components of the network, network administrators must quickly find the fault and timely elimination.
2, billing management Used to record the use of network resources for the purpose of controlling and detecting the cost and cost of network operations, it is particularly important for some public commercial networks.
3. Configuration management Configuration management is equally important, it is responsible for initializing the network and configuring the network to enable it to provide network services.4. Performance management It goes without saying that performance management estimates the operation of system resources and communication efficiency.
5, security management Security has always been one of the weak links in the network, and the user requirements for network security are quite high.
The osi network management standard defines five major functions of network management
FaultManagement, ConfigurationManagement, PerformanceManagement, SecurityManagement, and BillingManagement.
1, FaultManagement (FaultManagement): used to monitor faults in the network and notify the administrator in a timely manner to deal with them to ensure the normal operation of the network.
2, ConfigurationManagement (ConfigurationManagement): used to manage the configuration information of various devices in the network, including hardware information, software information, network topology, etc., in order to ensure that the network is correctly configured and updated in a timely manner.
3, performance management (PerformanceManagement): used to monitor the performance indicators of the devices in the network, and timely feedback to the administrator, so that administrators can optimize the network. SecurityManagement: Used to protect the security of the network, including authentication, access control, data encryption and so on, in order to ensure the safe operation of the network.
4. SecurityManagement: Used to protect the security of the network, including authentication, access control, data encryption and so on, in order to ensure the safe operation of the network.
5, BillingManagement (AccountingManagement): used to collect the use of resources in the network, and generate the corresponding reports and bills in order to billing and accounting for the network’s resources.
Briefly describe the concept and main functions of network management
Network management refers to the process of monitoring, configuring, controlling and maintaining computer networks. It includes the following main functions:1. Monitoring: By monitoring network devices, links and traffic, etc., real-time access to network status information, timely detection and resolution of problems.2. Configuration: Configuration of network devices and services, including IP addresses, routing, security policies, etc., to ensure that the network operates normally.3. Control: Management of network traffic and resources, optimize network performance, to ensure that the data transmission is smooth and reliable. 4. Maintenance: Troubleshooting and troubleshooting, implementing network security management, regular performance evaluation and optimization, and safeguarding network availability and security.
What are the functions of network management
1, failure management, the function includes the following five modules.
(1) monitor the failure phenomenon of the management object, or accept the failure report of the management object;
(2) use of spare network objects to replace the failure object to provide temporary network services;
(3) create and maintain the failure log record library, and analyze the failure log;
(4) carry out diagnostics of the fault, track down the point of failure to determine the fault nature, and define fault solutions;
(5) Repair and dispatch object faults to restore normal network services.
2. Configuration management
Configuration management is the process of obtaining data from the network and using that data to manage the configuration of all network devices. Through the realization of this function, network managers can grasp and control the state of the network, including the network of individual devices and their logical relationships, and the exact physical layout of the network in order to be the proportion of the party mapped to this logical map.
3, performance management
Performance management is mainly to evaluate the main performance indicators in the process of network operation, in order to verify that the network service is up to the expected level, to find out what has happened or potential bottlenecks, to form and report on the trend of network performance, to provide managers with a basis for decision-making. Performance management enables network administrators to monitor parameters of network operation, such as throughput, response time, and network availability.
4, security management
The responsibility of security management is to ensure that the network will not be illegal to use and damage, to ensure the safety of the entire network management system, while protecting the user will not be harmed by the use of the network. Security management is the constraints and control of access to network resources and their important information, including verification of network users’ access rights and priorities, detection and recording of illegal operations attempted by unauthorized users.
5, billing management
Billing management is used to measure the user’s use of network resources, and accordingly establish metrics, set quotas, determine the cost and bill the user. Billing management statistics help network administrators make decisions about how to allocate network resources.
