Why are there so many computers in Internet cafes that are not stuck? What router are they using?

What router should I use in an Internet cafe? Many people think that Internet cafes will use soft routing. Let’s put it this way, Internet cafes that use soft routing are either backward Internet cafes or have limited budgets.

Most Internet cafes today use firewalls as network exits, plus a behavior manager for traffic control.

Let me give you a simple example. I worked on a project before. There were about 400 people in a dormitory. The company provided them with wired and wireless networks. The export bandwidth was a 100M dedicated line. At that time, it was A firewall of a certain brand comes with professional flow control. I won’t say much else. I will just talk about how I do flow control. I first divide the entire broadband into two pipes, a large water pipe and a small water pipe. My water pipe is allocated 70 MB, and the small water pipe is allocated 30 MB. The flow between the pipes does not occupy each other. Even if the small water pipe reaches 30 MB, it will not occupy the 70 MB of the big water pipe. I use the big one for key tasks. , such as web browsing, network communication, online games, etc. As for the small water pipe, I use it to run P2P, software updates and other applications that occupy a lot of bandwidth. Then each user is limited to 4 megabytes of bandwidth, and there are also other things within the 4 megabits of bandwidth. Without flow control, each user can only use 2 MB out of 4 MB to run small water pipes.

I am only speaking roughly about the flow control mentioned above. There are many details. How detailed is it? I can even limit the maximum bandwidth of a certain application. For example, if I limit the total bandwidth of Thunder to 10 MB, it is not 10 MB for one person, but 400 people can only run 10 MB at most. If there is sufficient bandwidth, I allow each user to have a maximum bandwidth of 10 MB, and when the bandwidth is under pressure, it will be reduced to 4 MB.

Such fine traffic control is not available in soft routing. What I mentioned above is just the traffic control function of a firewall. It will be even more powerful if it is replaced with professional behavior management equipment.

Why don’t computers in Internet cafes freeze? The reason why you say this must be because there is a comparison. For example, your own computer has lag when playing games, but the Internet cafe does not have lag, right? This cannot be said to be related to the router. Although it is somewhat related, it is not the main reason.

There are three main reasons why Internet cafe computers play games without lag

1. Configuration

Today’s Internet cafes, especially new ones, have very high configurations. Because it wants to ensure that his computer can play various large-scale online games for at least three years, it will have this budget when configuring the computer. After all, configuring hundreds of computers at once is a huge expense, so it must be calculated carefully. Therefore, the configuration of Internet cafes is generally not low. If the configuration fails after three years, the Internet cafe owner can also replace a small part of the computers first, and the others will not be replaced immediately. If the computers in the game area are replaced first, the fee will be more expensive. If you play with game cards , If you can’t carry it, the Internet cafe owner will let you go to the game area to play.

2. Real optical fiber broadband

The broadband used in Internet cafes is different from that used in our homes. Although we now have 100M optical fiber broadband, it is not the same as the 100M optical fiber in Internet cafes. Yes, the one in the Internet cafe is much stronger in terms of stability, and its uplink and downlink are equal. The stability is mainly reflected in the fact that its network basically does not fluctuate. It is a dedicated line and is as stable as a mountain. The uplink and downlink are equal. This is one of the reasons why it is not stuck. If Internet cafes also use our home 100M broadband, the entire Internet cafe will basically go out of business and the card will not be good. Because the uplink is not enough, playing games requires uplink and stability. Have you noticed that, for example, if you go to an Internet cafe to play LOL, you will find that its value is almost fixed. It is the same and fixed on every computer. This is why the network is too Stable performance. Because of the stability, the latency in Internet cafes is much smaller. This is actually the main reason why Internet cafes play games without lag. If you don't believe it, just buy a computer with the same configuration as an Internet cafe, take it home and try it out, and it won't be as fast as an Internet cafe.

3. System

The system of the Internet cafe is installed on the server and is a diskless network.

It's the same as installing and restoring in an Internet cafe with a disk. Whenever the computer restarts, the computer will be restored, ensuring that every time you use the computer system, it will be the same as the one you just installed. This is why it does not freeze. In the past, when there were no solid-state drives, mechanical hard drives were too slow and not as fast as Gigabit networks. Therefore, many internet cafe computers with Gigabit networks could read and write faster than local computers. However, this is no longer the case. Just because it is restored every time it is restarted, the system used every time is new. This is also one of the reasons. At least it has something to do with it.

Probably these three points, I hope my answer will be helpful to you

Pay attention to playing computers and teach you how to play computers

.

To put it simply, Internet cafes have relatively strict requirements and professional management on computer configuration, system management, broadband bandwidth and Internet equipment.

1. The computer configuration of Internet cafes is actually not low.

For the sake of long-term interests, Internet cafe operators generally choose more mainstream computer configurations, especially in the now popular "Internet cafe" competition areas. In order to allow customers to enjoy a better experience, the CPU is generally They are all i5 or i7, with large memory of 8G or more, and most of the graphics cards configured are 1050, 1060 or even 1070.

"Internet cafe" e-sports area

2. Professional system management and optimization

At present, most Internet cafes adopt diskless technology and use specialized The computer system and software (games) are installed on this server. The computer host in the Internet cafe does not have a hard disk. Instead, it starts the system directly from the server image and reads the required application software and games. It is not only fast , and there is no problem of disk fragmentation, and it will not get stuck with more use.

Diskless system server

Another advantage of using diskless technology is that no matter when the customer is using the computer, no matter how the user operates, when the computer is shut down and restarted, the loaded system will still be The system status of the necessary applications is pre-packaged and installed, just like a newly installed system. There will be no accidental installation of various rogue software, and there will be no redundancies.

3. 100M (Gigabit) optical fiber broadband, exclusive bandwidth, fixed IP dedicated line. And uses professional-grade routers and enterprise-grade switches.

Using large-bandwidth optical fiber access can ensure that there are no obvious bottlenecks in download and upload speeds. Especially in some online games, it can bring a smoother gaming experience.

When the broadband speed is guaranteed, in order to ensure the stability of the network, it is also necessary to choose good network equipment to build the network.

Taking an Internet cafe with 150 computers as an example, the Feiyustar VR4920G router can be used with the VS6148XA Gigabit core switch to form a network.

Finally, professional network equipment requires specialized maintenance personnel to ensure that the equipment can operate at its best. Ensure that computers in Internet cafes run smoothly without lags.

Most people should have been to Internet cafes, and most of the people who go to Internet cafes do so to play games. If you often play electronic games in an Internet cafe, you will find that no matter how big the game is running or how many interfaces are opened at the same time, the computer in the Internet cafe will not freeze. This seems to be different from our own broadband. You may be wondering, what router does an Internet cafe use to ensure Internet speed? Let me take you to analyze why Internet cafe computers are not stuck:

First, Internet cafe computers have high configuration. As we all know, running games, especially large-scale games, has extremely high requirements on the computer's CPU, graphics card, and memory. In order to maintain the customer experience and maintain the operation of the Internet cafe, Internet cafes assemble high-end computers. Although the cost is higher, in the long run, the production-to-investment ratio is still relatively high.

Second, Internet cafe computers adopt a diskless system. All software including games are extracted directly from the server, eliminating the process of reading from memory, saving time and making you feel that the operation is particularly smooth. In addition, reading data directly from the server avoids generating a large amount of cache garbage and does not cause excessive load.

Third, Internet cafes have large bandwidth. Everyone knows that the decision-making power of Internet speed lies in bandwidth. No matter how good the equipment or router is without sufficient bandwidth, it will be half the result with twice the result. The fixed IP usually used in Internet cafes is different from the IP used in our homes. Our family uses an automatically obtained IP, and we use one server in one building, and a fixed IP in the Internet cafe. The running speed of each computer is parallel and will not decrease layer by layer. In addition, the routers used in Internet cafes are indeed relatively high-end and can match more devices. Coupled with customized switches, the Internet cafe's network is even more powerful.

Through the above aspects, you can know why the computers in Internet cafes are not stuck. The router is only one aspect, and the hardware and server are the key.

Why are there so many system computers in Internet cafes that are not stuck? It needs to be analyzed from several dimensions such as system, optical fiber access, and computer configuration.

System

1. Diskless system

On the one hand, it saves costs. On the other hand, you can choose a server hard disk with fast speed and large storage to improve the overall network. performance.

2. System restore

The system will return to the initial installation state after each shutdown, avoiding redundant configurations such as disk fragmentation, rogue software, and Trojan viruses.

3. Operating system optimization

Special system optimization has removed many unnecessary functions of the home and enterprise versions of the system and streamlined them. A dedicated maintenance company regularly upgrades and maintains the system.

Fiber optic access

Backbone 100M fiber optic access, with consistent uplink and downlink bandwidth. Internet cafes with good conditions will use dual line access to reduce game and web page delays. The mainstream uses TPLINK routers, and stability is guaranteed.

Computer configuration

Most Internet cafes play games, so the graphics card configuration is relatively high. It is biased toward mainstream configurations and has high gaming performance. Internet cafes do not have high requirements for stability. The purchase of motherboards and power supplies is relatively cheap, and the cost is tilted toward graphics cards.

Everyone is welcome to leave a message for discussion. If you like it, please follow it.

There are several main reasons why computers in Internet cafes are not stuck

1. Hardware configuration

Most of the computers in Internet cafes are not bad in terms of configuration, and some are still With standard e-sports configuration, you can play stand-alone online games without any problem. Some more luxurious ones will also be equipped with i7 1070 or above hardware. Therefore, in terms of hardware capabilities, most of them are very good, running Windows and games smoothly and easily.

Moreover, many Internet cafes have made improvements in heat dissipation, using water cooling or forced ventilation or other methods to improve heat dissipation efficiency, so as to minimize the deterioration of computer performance caused by overheating and frequency reduction.

2. Network configuration

Some online games, such as LOL, CF, Chicken Fighting, etc., have very high requirements on the network and require low packet loss rate and delay. That is to say, a stable connection and as few routing forwardings as possible are needed, so many Internet cafes optimize the network, on the one hand, by accessing high-quality optical broadband, and on the other hand, they are willing to use good machines in routing switches and other equipment. , and then cooperate with special network optimization software to achieve good network quality.

3. Storage optimization and operating system optimization

Many home computers actually have high CPU and graphics card configurations, but their storage performance is very poor. In this case, they generally do not have solid state configurations. It is caused by the hard disk, so generally adding a solid-state hard drive can solve it well. This has great advantages in the loading speed of games and timely reading of small files. Anyone who has played DNF knows that loading with a solid-state drive is completed very quickly, but some users who use mechanical hard drives may be stuck for a long time.

However, solid-state drives are too expensive, and the cost is high for Internet cafes. However, there is a way to solve the storage performance of mechanical hard drives, and that is disk array (RAID) technology. If you are interested, you can Baidu To put it simply, the work that originally only required one hard disk storage is handed over to several hard disks for coordinated work. Disk array technology solves the problem of incompatible storage capacity and storage performance, and the cost is also acceptable. Therefore, Internet cafes generally use diskless systems made of resource servers, that is, the host itself does not have a hard disk, so the resources, including the operating system and game clients, are stored on a dedicated resource server. The resources are obtained through a high-speed LAN or a dedicated interface, and the resource server It is a high-performance server using a disk array. By loading the image to run the operating system and games, you only need to build a high-performance resource server as a diskless system, and you can obtain high storage performance without installing a hard disk on each computer, thus saving costs.

In addition, many Internet cafe operating systems are customized win7, and some of the original win7 features that are not commonly used or that ordinary players will not use are deleted, and even office and other functions are deleted, and third-party WPS is used instead. Wait for replacement. This can reduce the background startup items of the operating system as much as possible and improve the smoothness of the system.

The fact that Internet cafe computers are not stuck has nothing to do with the router

First, the diskless system

The second configuration

The third real optical fiber

Let’s talk about the diskless system first. The diskless system is installed on the server. To put it simply, every time you restart, the system will be restored to the way it was set. When you just installed the system Whether the computer is fast or not, it must be fast. Every time you turn on the computer in an Internet cafe, the system has just been installed, so it must be fast too

Now let’s talk about the second configuration. My coordinate is Anyang, Henan Province. In third- and fourth-tier cities, the configuration of the 5-yuan area in the Internet cafe lobby here is generally a configuration of 7500 1065, 8g memory

With this configuration, it is no problem to play chicken or something, and Since you have gone to an Internet cafe, you must be playing some mass games. Basically, the most demanding mass game is chicken, so this set of configuration is completely satisfactory

And I don’t often play in the lobby. Yes, because I rarely go to Internet cafes. Now, I go to the private room to play.

What configuration is in the private room?

7700K 1080 16G memory, 2k screen 144, because my own computer is not 144, plus if we have friends to play hack together, we will go to this Internet cafe. This configuration costs 10 yuan an hour. I think it is a bit expensive, but it only costs 20 yuan all night. I think this is still acceptable.

And if we want to play some niche high-end games, this computer can also carry it

Finally, real optical fiber

What does real optical fiber mean? Well, we have two network cables at home, and I won’t talk about one mobile one. My mother gave me a mobile phone card, which can be plugged directly into the TV for use. I have one network cable for my computer, which was also given by paying the phone bill. What he said is 300M optical fiber

But the download speed is only 15-20 Mbit/s for the fiber optic cable in the Internet cafe.

The fiber optic cable provided by the Internet cafe is not given by charging the phone bill. The Internet fee is several thousand a year, and the download speed at home is the same as Internet cafes are incomparable.

The above

That’s it

As an Internet cafe practitioner, Xiaoxu will answer your questions!

First of all, why are there so many computers in Internet cafes that are not stuck? This question is obviously about your internet speed! Why isn't it stuck? Because the total bandwidth of the optical fibers used in Internet cafes is relatively large. For example, in my current Internet cafe, there are two commercial optical fibers of 50Mbps and three household optical fibers of 200Mbps. The download of one optical fiber can reach 20M/S, and usually when playing games It doesn't take up much network resources. Only watching videos or downloading files will occupy a lot of network resources.

People who go to Internet cafes to surf the Internet usually play games, and those who watch videos and download files only account for a small part. In order to prevent those who watch videos and download files from occupying all network resources, this involves routers, which are used in Internet cafes. It is an enterprise-level router, but it is under the management of the Cultural Affairs Bureau. Nowadays, formal Internet cafes basically use Wenwang Guardian. This is also an enterprise router. The most important function of enterprise routers is to limit the speed. For example, the total bandwidth download speed of Internet cafes is 50M. /S, then for the sake of balance, you can use the speed limit function and set the maximum download speed of each IP address to not exceed 2M/S. In this way, even if 10 people are downloading files, there will still be a total bandwidth of 30M available for each gamer. This way This ensures that players who download files will not occupy too many network resources and cause game players to freeze.

Enterprise routers also have an NB function, which allows you to add policies. For example, you use one telecommunications network (telecoms are expensive and must be used to play games) exclusively for playing games, and another cheap broadband network (taking mobile as an example). ) is used to watch videos and download files, then you can add policies in the routing to separate games and videos. Playing games will only use the telecommunications network, while watching videos and downloading files will only use the mobile network, so If they do not affect each other, the game will not freeze...

The above situations can only be played smoothly when the game official and the network are faultless!

First:

Most of the Internet cafes I have seen use the E3-1230V2 processor. This processor is a server processor, which is the number one brand of the E3 cult. Processor,

Second: And the computer in the Internet cafe does not have a hard disk, so there is no need to read the disk repeatedly and cause system lag.

Third: The computer in the Internet cafe restarts every time it is turned on. After that, you enter a virtual system. After you complete the operation on this system and restart it, the computer in the Internet cafe is equivalent to reinstalling the system.

In summary, for a relatively good configuration , and it's a new system every time you use it. A computer like this will definitely not be stuck.

If you have any questions, you can go to my GZH Thumbtack to ask.

Internet cafes use hubs, and the Internet cafe system has an independent server. Each computer in the Internet cafe has a restore Elf, so it’s generally not too stuck! Moreover, the Internet cafe has engineers who regularly come to maintain the machine
