Chapter 136 Don't worry about everything

My father came over and was obviously ready to talk to Niu Ben about what had just happened.

Although he is old and doesn't know anything about Sora Aoi, Ozawa, Yui Hatano, etc., even according to the traditional vision and views of the older generation, he can clearly know what is good and what is bad. Like that Hatano Yui teaching**, although the picture is very short and did not enter the stage of * live ammunition at the beginning, the shooting method and angle of this film make people know what will happen next at a glance.

After all, the so-called island love action blockbuster sells meat, not the plot or anything at all.

In this situation, my father naturally quickly recognized that the big screen was not a good thing. Therefore, I want to come here to remind Niu Ben to pay attention to the impact. However, when he walked this way, he saw Niu Ben righteously scolding the students-like guys. While he was full of great comfort, he felt that he didn't need to say anything. Look, my child is a very upright young man. His position is so firm that he will obviously not be affected by those evil spirits!

Therefore, my father came over and just chatted with Niu Ben casually. Not long after, he walked away leisurely. He just told Niu Ben to take care of the Internet cafe by himself.

Of course, this is just a small episode. After that, although Niu Ben called Zhao Tuozi to him and scolded this guy fiercely, he could only give up the matter. By the time the full-color screen was fully debugged, it was almost noon. After dinner, Niu Ben found Zhao Tuozi again. The purpose of his coming to the Internet cafe this time was to find inspiration. Although he needed to deal with some trivial things like before, he could not reverse the primary and secondary.

The two sat down in the small corner for people to rest on the second floor. Niu Ben did not beat around the bush and asked directly, "Lao Zhao, as a supervisor for so many days, you must have a considerable understanding of the Internet cafe. Please help me think about it. If you urgently need a software, the Internet cafe needs the most What kind of software should be installed first to make everyone feel satisfied.

"Software!" Zhao Tuozi swore and said, "If I say so, of course it's better to get a bandwidth diversion software. You don't know. I have a headache these days. There are 300 computers and 40 megabytes of optical fiber access in the Internet cafe, but during the peak of the Internet, the network is still not very smooth. Sometimes people even play World of Warcraft, and after entering the game, it shows a delay of more than 1,000. How can it be comfortable to play!"

"Well, the bandwidth is not enough?" Niu Ben was stunned and immediately attracted attention by Zhao Tuozi's words: "Didn't the main router make a strategy? 40 megabytes of optical fiber is evenly distributed, and each computer can be used for more than 100K. This should not be a big problem."

"At ordinary times, this problem is not too big. After all, Internet cafes are optical fiber access, and the upstream and downstream are the same width. Each computer is allocated 100K, which is almost the standard configuration of most Internet cafes. Under normal circumstances, whether you play games or do other things, it is enough. But the problem is..." Zhao Tuozi looked at Niu Ben and said helplessly, "We are next to the school, and the situation is relatively special."

Niu Ben was somewhat puzzled and said, "What a special law!"

Zhao Tuozi muttered a little depressedly: "Internet cafes in the city play a lot of games, and they also watch movies downloaded by themselves. But we are different here. Those students, especially some girls, spend almost all their time surfing the Internet on PPTV, fast broadcast, or software such as Penguin Live. As you know, all these things can drag the network speed. One or two are fine. If there are more, basically, the game can't be played!"

"That's it!" Niu Ben finally understood what Zhao Tuozi said. That is, although the routing strategy set by the Internet cafe allocates bandwidth evenly to each computer, in fact, this only refers to the downline bandwidth. The so-called downbound bandwidth is actually how much data you can transfer at a fixed time. Like Internet cafes, the most basic is 10 megabytes of optical fiber, which means that from the network to the Internet cafe, it can accommodate up to 10 megabytes of data traffic in a fixed time.

This statement is also common in home broadband. For example, your home is four megabytes of broadband, and his home is two megabytes, or one megabyte, which means that the maximum amount of network data can be transmitted to your computer at a fixed time.

Some people may say that I use 4 megabytes for a computer in my home, and many computers in the whole Internet cafe only use 10 megabytes together. Isn't this Internet cafe so scum and painful? Of course, we have to explain the difference between broadband and optical fiber, although the former is the access mode, and the latter is defined as the transmission medium, which are two different concepts. However, according to the low-end practitioners in Internet cafes, they can also be clearly divided.

This is the so-called up and down.

Upline refers to your bandwidth. For example, your home is four megabytes of access, while downbound is the maximum amount of data traffic that can be transmitted from your computer to the network. Why is the Internet called the Internet? Because it requires communication and transmission between each other, the so-called network speed is not only the maximum value of the data you get from the network, but also includes the maximum amount of traffic that can be transmitted from you to the network.

The optical fiber of the Internet cafe is the same. For example, if the Internet cafe has 10 megabytes of access, then its downstream has the same maximum traffic of 10 megabytes.

As for home users, the size of the down line is generally much smaller than that of the upline. For example, if your home goes to telecommunications to receive two megabytes of broadband, then your downline is much smaller than this two megabytes. Generally, the up and downbound and down of home users are two to one. In other words, your two megabytes of broadband, then the downs that telecommunications give you are generally up to one megabyte, and in some places, it is even less than one megabyte.

Well, this is a very simple thing. In fact, there is no need for popular science.

It is also very simple to know the up and down data of your home. You just need to open a website and enter "192.168.1.1" in the web address bar. After entering, a window will pop up and let you enter your account password. Generally, if the broadband cat in your home has not been moved by anyone, this account password is set uniformly when leaving the factory. The account number and password are exactly the same, and they are all "admin".

......

Back to the point, I heard Zhao Tuozi say that many people use tools such as QQLive. Niu Ben also felt a headache at that time. This tool is very comfortable for single computers for home users. However, for Internet cafes, it is a headache for every Internet cafe practitioner. Because this kind of thing transmits data from you to the Internet while looking at it, which will crazily use up your large amount of down traffic.

Up and down can be compared to two roads going in and out. When the way out is occupied a lot, there are still so many people when you come in, so it will be very difficult to get out after coming in, just like encountering a traffic jam. The data enters the Internet cafe through the upbound road, but the down road transmitted is occupied. It can be imagined that after the data congestion, you absolutely can't get up quickly.

In this case, many Internet cafes have set restrictions on the use of playback tools such as Qvod or Penguin Live on their servers.

Perhaps many people have had the experience that there is an icon of this kind of tool in the Internet cafe, but when you double-click to open it, the whole tool just flashes on the desktop and completely disappears.

Basically, Internet cafes have restricted the use of this player.

Khan, after the update yesterday, I have been working part-time on the vertical and horizontal website until ten o'clock in the morning, but I still have three-fifths of the work to finish. It seems that after finishing the code today, I have to stay up all night. Sad, ask for some red tickets to comfort you.
