What are the components of a network management system?

It is mainly composed of three parts: computer system, data communication system, network software and protocol.

The computing system is simply composed of hardware and software, and the hardware system is mainly composed of processors, memory, input and output control systems and various external devices; Software is divided into system software, support software and application software. System software consists of an operating system, utilities, compilers, etc.

Network software generally refers to the system's network operating system, network communication protocol and application-level special software that provides network service judgment functions. Common network operating systems include UNIX, Netware, Windows NT, Linux, etc.; A protocol is a collection of rules, standards or conventions established for data exchange in a computer network, and the network protocols we are familiar with are HTTP, HTTPS, FTP, etc.

The data communication system refers to the system that connects the data terminal equipment distributed in remote places with the computer system through data circuits to realize data transmission, exchange, storage and processing.

Networks can be mainly divided into: local area network, metropolitan area network, wide area network, wireless network.

The network pipe flow management system includes: management process, managed object, ** process, network management protocol and management information base.

The network management system is composed of five parts: management process, managed object guessing spine, ** process, network management protocol and management information leakage database.

There are three ways to unify multiple network management systems together, one is the format conversion method, that is, each subnet management system converts the format through the ** program, so as to identify and share resources with each other, which is a kind of decentralized management.

Manner. The other uses a hierarchical network management platform, that is, to establish a more advanced management system, and the communication between the high-level network management system and the low-level network management system is a kind of distributed management.

Manner. The third is the standard method, which is to follow the standard specifications and protocols, such as the establishment of a comprehensive network management system.

1.Network topology: The envelope includes network devices and network connection methods.

2.Network device information: includes the model, version, and configuration parameters of the device.

3.Host information: includes the host's operating system, applications, and hardware configurations.

4.Network interface information: includes the number of interfaces, bandwidth, and status of each device.

5.Network traffic information: includes the real-time status and historical trends of network traffic.

6.User management information: including users, rights, etc.

7.Device monitoring information: including device running status, alarm information, and fault events.

8.Security management information: includes security management functions such as firewall, intrusion detection, and traffic analysis.

9.Log management information: includes macro log information for devices, hosts, and networks.

10.Troubleshooting information: including diagnostic tools, remote control and other tools and methods for troubleshooting.

The computer network system is composed of computer system, data communication and network system software, and mainly has the following components from the hardware point of view:

1) Terminal: The equipment used by the user to access the network, such as teletypewriters, keyboard monitors, computers, etc. In the local area network, the terminal is generally served by a microcomputer, called a workstation, and users share online resources through the workstation.

2) Host: A computer system that is used for data analysis, parameterization and network control, including external devices, operating systems and other software. In the local area network, the host is generally served by a higher-end computer (such as 486 and 586 machines), called a server, which should have rich resources, such as large-capacity hard disks, sufficient internal storage and various software.

3) Communication processing machine: A communication control processing machine set up between the communication line connected to the terminal and the host unit, which shares the control and management of data exchange and various communications. In the local area network, there is generally no communication processor, and the host directly undertakes the control and management tasks of communication.

4) Local line: refers to the line that connects the terminal with the node host, including a concentrator or a multiplexer. It is a low-speed line with low cost and efficiency.
