The Following is a Brief Introduction To Network Engineers

Brief Introduction To Network Engineers

First of all, let’s talk about the classification of the network engineering industry. The type of service companies, it is divided into party A, integrators, and manufacturers.

Let’s talk about the manufacturer first. The certification CCNA and HCNA we are learning now are the manufacturer certifications of Cisco and Huawei. 

The manufacturer mainly produces and develops equipment, but the manufacturer also provides after-sales problem handling and implementation work, because commercial network equipment is not easy to configure at all, so manufacturers also propose their own certification.

So that more engineers can learn their configuration methods and many customers, they will not be able to use after buying equipment. At this time, they need the technical support of the manufacturer.

Then there are integrators. For many customers, they need more than network equipment, such as servers, integrated wiring, software systems, and so on. The integrator is to provide an overall comprehensive solution, which may be Cisco for network equipment, IBM for server, oracle for database, and so on.

What About Party A?

Party A just spends money to buy equipment. They need to have a set of IT systems that can meet the needs of use.

In most cases, the integrator is responsible for installation and debugging, and then the customer’s IT department is responsible for operation and maintenance. There are also many parties who outsource operation and maintenance work to integrators.

A simple understanding is that Party A spends money, the integrator is responsible for intermediate integration, and the manufacturer produces equipment.

As a network engineer, the best attribution is Party A and the manufacturer. Party A and the manufacturer are relatively stable, the manufacturer’s treatment is good, and it is easy and pleasant to work in Party A.

The integrator recommends the students who have just entered the industry, because they can contact more manufacturers’ equipment, and Technology improves fast.

Classification of network engineers

Next, let’s talk about the choices we have just entered in the industry, which are mainly divided into pre-sale and after-sale.

First of all, 

What is pre-sale?

Pre-sales is the technical support that customers are ready to purchase.

For example, when Party A puts forward requirements and budgets, sales will do customer relations at this time, but the customer needs to provide technical solutions, product selection, bidding, technical testing, etc.,

And these sales are not very understanding. And pre-sale is to have certain technical ability and use technical means to solve the problems raised by customers.

Talking about the digression of the Internet industry, it is often said that pre-sale pits are dug, and after-sale pits are filled. In order to meet the needs of sales and customers before the sale, many times there are plans that are difficult to implement.

When the purchase of the equipment needs to be carried out according to the pre-sales, the after-sales engineer really wants to cry without tears.

What is after-sales?

After-sales is when customers buy equipment, and manufacturers or integrators need to provide after-sales services such as installation, shelf, and debugging. In many cases, after-sales needs to be cut over and transformed, in most cases, it needs to be carried out at night.

Whether it is after-sales or pre-sales, both manufacturers and integrators have positions.
