In fact, many people don't know much about the network engineer industry, so my answer this time is to give a detailed explanation of the network engineer industry. The original intention is to help fresh graduates who are looking for jobs, students who are interested in online learning, and network practitioners or people who plan to quit their jobs to learn more about the online industry and related employment.
# Dry goods warning. There is a full circuit diagram of the career development direction of network engineers, and there are answers to various experiences and insights of network engineers in the past ten years. Technical panorama of network engineers with zero-based entry and suggestions for entry.
The following is a general brain map made by Master A according to the career trends of colleagues and Master A students in recent ten years. If there are any imperfections, please give us your advice.
First of all, the respondent emphasized that the network engineer here is not limited to a small network, but a large-scale industrial network platform. Because the meaning of the word network is too wide, and because of its TO B attribute, it is deeply misunderstood by the broad masses of the people. They think that the network engineer is web workers, a network administrator, and the network engineer is a very low-level industry and occupation, and even labeled as "hard work", "migrant workers", "no future" and "no technical content".
On some occasions, network engineers are also considered to be engaged in residential broadband, integrated wiring, computer maintenance, websites and other work. In fact, this is a deep misunderstanding of the profession and industry of network engineers. Next, the master will explain the direction of the network engineer industry and career according to these three directions.
1, depending on the technical direction
(1) Route switching (with detailed technical circuit diagram): This is the basis of computer network. If you are engaged in this industry, you must have knowledge of routing and switching, otherwise you can't understand the context of the network and it's easy to get to the mountain. If we want to engage in routing switching, at present, China generally refers to the manufacturer system represented by Huawei and Xinhua, and other manufacturers include Ruijie, Maipu and Shanghai Boda.
The job content is generally to provide technical services for various industries, government agencies and operators. At present, with the integration of the industry, the days when only one VLAN is very popular have passed. At present, it is far from enough to know only routing and switching, and the industry has new requirements for the technical depth and breadth of practitioners.
When applying for a job, the employment requirements of many companies will state that those with intermediate certificates from Huawei, Xinhua III or Cisco are preferred, because it is generally believed that people with intermediate certification skills from manufacturers have the ability to operate general projects and are more easily understood and recognized by customers. I have worked as a network engineer for several years, and the established standard in the industry is to have advanced certification of Huawei/Cisco/Xinhua, that is, IE certification.
In terms of salary, the salary of manufacturers is generally higher, and the annual salary is 10-50W or even higher. Integrators, distributors and small manufacturers are generally treated in general.
If some students don't know their technical level, here is a skill map compiled by the master for reference. If you want the original document, please send it privately.
(2) Network security:
At present, China mainly works in security hardware manufacturers, service providers or integrators, and evaluation institutions. For example, Kai Anxin, Tianrongxin, Venus Star, Lv Meng, Shanshi Net Branch, Shen Xin, Bangbang Security, Golden Shield Evaluation, Huazhong Evaluation, etc., technically require practitioners not only to have security technology, but also to have relatively solid routing and switching technology, and even some companies need to know some programming and automation technologies.
The work contents generally include penetration testing, security incident analysis, traceability and disposal, security rectification, security reinforcement, security assessment, system security construction, security project planning, construction and implementation, and security emergency response.
If you apply, the company generally requires routing switching, and at the same time knows some network security technologies and network security laws.
Generally speaking, companies with network security offer higher salaries. The annual salary of high-paying undergraduate students can reach 16W. If you do penetration test, you can get 18-20W annual salary, and the low salary is also 6- 10W.
(3) Cloud computing:
At present, China is mainly engaged in cloud computing vendors, cloud service providers, large enterprises and institutions, such as Huawei, Xinhua San, Shen Xin and other vendors and their distributors. Generally speaking, established ICT companies will have corresponding cloud computing product lines. In addition, you can choose to work in cloud service providers such as Tencent Cloud, Alibaba Cloud and ucloud. These cloud service providers need technical support from network engineers.
The job content is generally like this: take the manufacturer as an example, in fact, it is similar to a network engineer. If it is a cloud service provider, it is generally technical support or remote technology.
If you are looking for a job, you generally need to know the network foundation, virtualization, linux foundation and network security technology.
If the salary is paid, the annual salary of fresh graduates will be 10- 15W, and even the salary offered by some companies in some first-tier cities will be higher.
(4) Wireless, voice, disaster recovery, storage, data center, big data, applications, etc.
Few specialized companies only do this, but most comprehensive manufacturers will involve one or several businesses. If you want to do these things, you can be a WLAN engineer, a storage engineer, a data center operation and maintenance engineer and so on.
If you are looking for a job, you should have basic knowledge of network, enterprise-level WLAN, enterprise-level storage and other specific professional technologies.
If the salary is paid as usual, the difference will be greater ~ if you want to know more, you can consult privately.
2, according to the enterprise employment situation
Generally divided into these four directions.
If the small partner is not clear about the difference, you can refer to the enterprise description.
Manufacturer: To provide products or services produced by itself for profit.
Operator: responsible for providing operating services to end users according to the products or services provided by manufacturers in order to obtain profits.
Channel dealer (distributor): Manage sales channels to make profits.
Agency: the manufacturer authorizes the representative of a certain region to act as an agent for certain functions of the manufacturer, and to distribute a certain product and obtain profits.
System integration vendor: with certain qualifications. For large-scale projects, the general contractor will be selected through bidding, and the general contractor will subcontract the subsystems.
Generally speaking, the number and types of jobs that manufacturers can provide are more complete, the process is more detailed, each position has its own things, and the treatment is generally higher; Large-scale integrators have done a good job, and they can provide more jobs and benefits.
Channel dealers, agents, distributors and small integrators generally focus on a certain region or several regions. From first-tier cities to eighteenth-tier cities, there may be coverage, and the treatment is generally not as good as that of manufacturers. However, if you can become a business partner of a company, it will be a good choice.
3, according to the job.
This map is subdivided according to the above two general directions, and the points are relatively fine. Generally speaking, the industry is often divided into two general directions: technology and market.
