Chapter 11: Private Experts

Guo Pengfei and Zhou Buqi were the first to go.

In the network center, several maintenance workers were smoking and blowing away, wearing uniform uniforms.

However, the failure of the campus network this time was not a construction problem, but a technical problem, which these maintenance workers could not handle.

"Xiao Guo, are you here?"

A middle-aged man wearing glasses stood up, smiled and waved to Guo Pengfei.

"Brother Liu, have you found out? Where is the problem?" Guo Pengfei obviously knew him, and then introduced to Zhou Buqi in a low voice, "This is Captain Liu of the construction team, and they laid the optical fiber."

"It's not our problem."

Liu Dui casually threw the cigarette butt in his hand on the ground, and stomped it hard with his foot.

Zhou Buqi frowned secretly.

This work style is really wild. This is the monitoring room on the IP side, which is at the laboratory level.

Guo Pengfei went to check the router.

Zhou Buqi didn't understand technology, so he hilariously spanked these maintenance workers, told two nasty jokes, and they hit it off after a while. Someone offered him a cigarette, but he hesitated a few times before refusing.

He was used to smoking in his previous life, but in this life he has not yet become addicted to smoking. There are a lot of good times waiting to be enjoyed in the future, there is no need to affect your health for a moment of refreshment.

When they were almost familiar with each other, Zhou Buqi showed his fangs and began to sell calling cards.

Every time a hero slaughters more dogs.

When these maintenance workers saw the pitiful appearance of the mountain children in the photos, they were a little moved and sighed. When they heard that Zhou Buqi would cooperate with the business hall to donate money, they all applauded. I heard that this kind of campus card has great discounts, and when the denomination of 100 yuan has an extra gift of 25 yuan for phone calls, I am all excited.

Then, six maintenance masters bought more than 20 copies in one go.

If it weren't for the limited cash on hand, they might have bought more.

Guo Pengfei squatted over there to check the router, and at the same time pricked up his ears, listening to Zhou Buqi chatting with these social people without any barriers, he was startled for a while, and felt more and more that this kid had a future.

Seeing him casually selling more than 20 cards, I couldn't help laughing and crying.

It's true that no grass grows anywhere.

"How? Have you found out what's wrong?"

After selling the cards, Zhou Buqi walked over with a smile.

Guo Pengfei said: "I came here once the day before yesterday. When I let the traffic run, everything was fine. But it was disconnected yesterday. I thought it was because the optical port was down, so I told the staff to restart it, and it was fine. I didn't expect , it broke again today..."

Zhou Buqi felt dizzy for a moment, "Don't tell me these things, I don't understand technology, what I'm asking is the result."

Guo Pengfei looked at him contemptuously, "I speculate that the optical power of the DDN and the central switch does not match. But this is just speculation, and the data needs to be copied out to compare with the parameters on the other side."

Zhou Buqi nodded and didn't say much.

He understands simple computer knowledge, but he doesn't understand it.

After a while, four big cows came.

One is a postdoctoral fellow, and three are PhD candidates.

Everyone else stayed behind, and only Guo Pengfei went over to introduce the situation to them.

After a while, a doctor surnamed Li asserted: "It should be right, it is a problem of optical power. I have data here, and compare it."

Then, take out the laptop, connect, and operate in one go.

Check it out, it really is!

The optical communication of Long March Technology used at the other end has relatively high power, but not too much, so it can run when it is started. However, if the running time is long and the load is heavy, the optical port of the router will be killed.

Found the problem, how to solve it?

The postdoctorate had a heated discussion with the doctors, and Guo Pengfei obediently stepped aside.

"Why don't you discuss it?" Zhou Buqi pushed him.

Guo Pengfei rolled his eyes, "Do you think I'm a god? I'm just a sophomore, okay? I don't understand the theory of optical transmission they're talking about."

Zhou Buqi just smiled, "You don't understand, and neither do I. It seems that our level is similar."

Guo Pengfei didn't want to talk to this shameless guy.

Five minutes later, the results of the discussion came out.

Dr. Li said: "You need to apply for a fund from the school to buy an optical attenuator, and just reduce the strength of the transmitted signal at this end."

"Optical attenuator? Doesn't it exist in China?"

"Well, it needs to be imported."

"how much?"

"It's not expensive, maybe $5,000."

After thinking about it for a while, Dr. Wang said.

Zhou Buqi and Guo Pengfei looked at each other and said "ho".

As expected of a postdoctoral fellow, what a bold tone!

5,000 US dollars, this is foreign exchange, how difficult is it to apply?

But if you don't apply for the purchase, the campus network will have frequent failures this semester, which will be troublesome. The key is that even if the funding application is successful and the order is successful, it will take half a month to ship it back from abroad.

School has started!

Many courses require network services.

At this time, Captain Liu from the maintenance team came over, lit a cigarette, took a deep breath, squinted his eyes and asked, "Well, I'm just a big bastard, I haven't graduated from junior high school, and I don't know any advanced theory. I heard that the power of the two sides does not match?"

Postdoctoral fellows and Ph.D.s kept silent.

Zhou Buqi didn't discriminate by status, and said with a smile: "Yes, that's about it. Our power here is low, and the power coming in is a little bit bigger, and it won't be able to handle it after a long time."

"That's not easy?"

Team Liu let out a hey laugh, revealing his big yellow teeth.

"Simple?"

Several high-achieving students all sneered, mocking.

Guo Pengfei also frowned, feeling that Team Liu's tone was too loud, like Zhou Buqi.

Post-doctoral Wang took three doctors to check for so long. Do you, a maintenance worker, understand optical principles and network data transmission protocols?

If it is really that simple, do we still need to spend huge sums of money to buy optical attenuators?

Zhou Buqi had a different expression. He glanced at him and asked with a smile, "Brother Liu, can you handle it?"

Captain Liu grinned, "Try it?"

"Then try it." Zhou Buqi made a gesture of invitation.

"Don't move!" Postdoctoral Wang felt humiliated and shouted, with a gloomy face, "This is a high-tech product, what if it breaks? Also, this is the network center and the experimental base, so no smoking!"

Captain Liu was stunned for a moment, then laughed, "I'll just talk casually, haha, then I won't try it, I won't try it."

After finishing speaking, he kept waving his hands, not annoyed at all.

Zhou Buqi was not happy, and grabbed him, "Brother Liu, you should take action, maybe it will be repaired? It can also save the country's foreign exchange reserves of 5,000 U.S. dollars."

Postdoctoral Wang felt offended and said displeasedly, "Who are you? What right do you have to be here?"

Zhou Buqi glanced at him and didn't bother to respond.

What is a postdoc?

That is, after graduating from a Ph.D., there is no job yet, and a special position that stays in the school and participates in the project with the tutor.

You know, this is 2004!

All walks of life in the country are in urgent need of high-end scientific and technological talents. Doctors in the communications industry from top universities like HKUST are all leaders.

If you are really capable, is it necessary to stay in school and continue to help the tutor?

I have already gone out to lay down my own world.

Guo Pengfei didn't want to make a fuss, so he smoothed things over and said, "Senior Brother Wang, why don't you...or just let Team Liu try it out. He has been in the industry for more than ten years, so he might not be able to do it in theory, but he is still very good at it. .”

Dr. Wang snorted coldly and stopped talking.

Guo Pengfei has a lot of face. His mentor, Changjiang scholar, Ph.D supervisor, and vice president Li Zhengming once said that this kid's future is limitless.

With the help of Zhou Buqi and Guo Pengfei, Captain Liu still made a move.

He didn't seem to have dealt with any high-tech equipment at all. He tilted his head, smoked a cigarette, squinted one eye, picked up the fiber optic cable a few times, and then turned around and said, "Old cow, where's the marker?"

The old cow came over to take a look, and said naively: "Use a pencil, that's fine."

Captain Liu took the pencil, circled the aperture a few times around the pencil, and as soon as he stretched out his hand, Master Niu handed over the black tape. Captain Liu wrapped it casually with black tape a few times, and the whole set of movements did not have any precise calculations and high-tech content.

It's all about guesswork!

Or rather, it's all about experience.

"Let's try it now."

Captain Liu fixed the pencil to the base of the wall, then waved his hand, "I don't understand the computer thing."

In the network center at this time, it was so quiet that even the sound of breathing could be heard.

Post-docs and Ph.Ds, including Guo Pengfei and Zhou Buqi, all had bright eyes.

Even Zhou Buqi can understand Captain Liu's handling methods.

This is the simplest physics I have learned in junior high school, it is the principle of transformers!

Reliable!

Guo Pengfei knew that this was the expansion of optical decay, so he couldn't wait to operate the laptop, compare the parameters, test the optical power... everything is normal, it's done!

"Captain Liu, you have done us a great favor, now we don't need to purchase optical attenuators."

Guo Pengfei was very excited. When he looked back, he found that Post-Dr. Wang and the three doctors had very ugly faces.

The corner of Zhou Buqi's mouth curled up, and he started selling cards again, "Several seniors, I have a batch of campus cards here, and the discounts are great..."

"don't want!"

Before he finished speaking, he was interrupted by Post-Dr. Wang.

Zhou Buqi continued: "We got in touch with Telecom, and the funds raised will be donated to children in impoverished mountainous areas. Buying a card is equivalent to showing love..."

"Not interested in!"

Post-Dr. Wang interrupted him directly, with a gloomy face, and waved his hand, "Let's go!"

Then, several high-achieving students left directly.

Guo Pengfei stared blankly at their backs, his face full of disappointment.

The maintenance team also packed up and left.

Zhou Buqi patted him on the shoulder, "Do you understand what happened this time?"

Guo Pengfei was a little frustrated, "Senior Wang's technology is very high. I admired him very much for a time. I never thought... I didn't expect that a technical problem that they couldn't solve was solved by a maintenance master."

Zhou Buqi said: "The sophistication of theory cannot be equated with the level of ability. In fact, if you look at the world's business tycoons, few of them are highly educated. Doctors and post-doctorals rarely succeed in starting a business. Do you know why? ?”

"To get out of the ivory tower." Guo Pengfei narrowed his eyes and sighed.

"It's here."

Zhou Buqi pointed to his head, "The way of thinking needs to jump out."
