For the network management of internet cafes, it is basic to have comprehensive knowledge and practical ability.
However, qualified network managers still have many things. Let's see:
Knowledge structure of network administrators
Just graduated from computer-related major, far from a qualified network manager. With the rapid development of network technology, the content of textbooks has become very outdated. Therefore, we should extensively dabble in network management related fields and complete the most basic knowledge accumulation.
● Understand network design.
Have rich knowledge of network design, be familiar with network wiring specifications and construction specifications, understand network equipment such as switches, routers and servers, master the basic and related technologies of local area networks, plan and design local area networks and wide area networks including routing, and provide complete solutions for small and medium-sized networks.
● Master network construction.
Grasp the basic knowledge of network, deeply understand the TCP/IP network protocol, independently complete the installation, connection, configuration and operation of network equipment such as routers and switches, build a multi-layer exchange enterprise network, and realize network interconnection and Internet connection. Master the use of network software tools, quickly diagnose, locate and eliminate network faults, and correctly use, maintain and maintain hardware equipment.
● Familiar with network security
Design and implement a complete network security solution to reduce losses and attack risks. In Internet and LAN, routers, switches and applications, and even loosely managed security devices may be the targets of attacks. The network must go all out to strengthen its alert and prevent hackers, outsiders and even disgruntled employees from threatening information security, information integrity and daily business operations.
Familiar with network operating system.
Familiar with Windows and Linux operating systems, capable of using advanced Windows and Linux platforms to provide successful business solution design, implementation and management for enterprises.
● Understand the Web database.
Knowing the basic principle of Web database can be used to implement and manage the Web database system and realize the comprehensive application of enterprise data.
Quality and ability of network management
A real network administrator should have a deep understanding of network hardware and operating system. In other words, as a network administrator, you should be familiar with the performance, connection and configuration of network equipment, master the construction, configuration and management of network services, have a deep understanding of network protocols and network security, skillfully use network diagnosis software tools, and eliminate network faults in time.
● Self-study ability
Network management should have a strong thirst for knowledge and a strong ability of self-study. First, network knowledge and network technology are constantly updated, and there are many things to continue to learn. Second, most of the knowledge in school textbooks is too old and divorced from the reality of network management. A lot of knowledge must be learned from scratch. Third, network devices and operating systems are very complex, each with its own advantages, which are suitable for different environments and needs and need to be fully understood and mastered.
● English reading ability
Because most of the new theories and technologies are in English, and most of the instructions of network equipment and management software are in English, network managers must master a large number of computer professional vocabulary in order to read the original white paper and technical materials smoothly. The easiest way to improve reading ability is to choose the technology you are familiar with first, and then log in to official website, the manufacturer, to read the technical white paper, so as to understand the expression of technical documents. When you encounter new words, you can use an electronic dictionary to translate them online.
Low hands-on ability
As a network administrator, there are many times when you need to do it yourself, such as the connection of network equipment, the construction of network services, the setting of switches and routers, the implementation of integrated wiring, the expansion and upgrading of servers, and so on. Therefore, network management must have a pair of dexterous hands and strong hands-on ability. Of course, you should read the technical manual carefully in advance and make necessary theoretical preparations.
● Creativity and adaptability
The direct functions provided by hardware devices, management tools and application software are often limited, but the network demand is unlimited. Satisfying unlimited demand with limited functions requires network management to have strong adaptability, and creatively realize various complex functions by using existing functions, means and technologies to meet various needs of users. Taking the access list as an example, port restrictions can not only restrict access to network services, but also limit the spread of worms.
● Ability of observation, analysis and judgment.
Have keen observation ability and excellent analytical judgment ability. Error messages, logging, LED indicators, etc. Will prompt the possible cause of the failure from different sides. The more detailed and comprehensive the observation of the fault phenomenon, the greater the chance of troubleshooting. In addition, through frequent and careful observation, potential network hidden dangers can be eliminated in time. Network is a complete system, and the relationship between fault and cause is complicated. It may be that one cause has multiple influences, or that one influence has multiple reasons. Therefore, network management must analyze problems with a comprehensive, dynamic and connected vision, be good at logical reasoning, and discover the essence of things from complex phenomena.

Knowledge and ability are complementary, knowledge is the foundation of ability, and ability is the application of knowledge. Therefore, the two should not be neglected. We should follow the principle of network theory first, then actual operation, and improve our practical ability on the basis of understanding the basic principles. It is suggested to use VMWare virtual machine to build a network experiment environment and build and configure various network services. "Interest is the best teacher." As long as you love the network management profession, I believe that through your own efforts, you will soon grow into a qualified network management!
