Zhou Shuo looked at the only person sitting in front of the computer in the software laboratory, and couldn't help asking, "Director Huang, isn't she a staff member of the Science and Technology Commission?" Why is it in the sixty-four again? ”

Huang Shi said with a smile: "You said that it is less than, hehe, let's let Director Yu talk about this matter." ”

Hearing Huangshi's name, Zhou Shuo faintly guessed. Sure enough, Director Yu said proudly: "Ha Luha, in fact, this is my daughter, Yu Qiong." She is not a staff member of the Science and Technology Commission, but the youngest researcher in the 64th Institute! ”

Zhou Shuo saw that Yu Qiong was twenty-three or four, and she had already become a researcher at this age, even if her father was the director of the Science and Technology Commission, it was not easy.

Yu Qiong was wearing a white coat today, and her hair was still tied behind her head with a pencil, even if a group of people were standing around and talking about her, they didn't see her look up.

As soon as the crackling sound of her keyboard stopped, she stood up and took two steps towards the door, and suddenly said to Zhou Shuo, "Please give way." ”

Zhou Shuo hurriedly dodged aside when he heard this, only to find that there was a filing cabinet behind him. Yu Qiong and the others didn't even say hello, they took out a folder inside, opened the folder and sat back while looking at it.

Director Yu smiled awkwardly: "Hehe, this kid is not very good at coming to trouble, don't mind Principal Zhou." ”

Zhou Shuo waved his hand, looked at the folder in her hand curiously, and said, "It's okay, Director Yu don't care." If I'm not mistaken, Yu Qiong is doing cascade dynamics analysis, right? ”

As soon as the so-called connoisseur makes a move, he will know if there is one. Zhou Shuo's only one question immediately made everyone know that he was by no means an ordinary civil science, but had a considerable understanding of the Internet. People's success really doesn't depend on luck, and Microsoft won't be wronged.

Zhou Shuo took two steps forward, looked at her computer screen, pointed to a string of formulas on it and said, "You can't do this, the network topology has the characteristics of scale-free, and the node degree division in the network is heterogeneous and obeys the power-law distribution. If you distribute connections according to your model, if you are attacked or an unexpected situation occurs, it is likely to overload the nodes and even lose their efficiency! ”

Yuqiong raised her head, helped her thick-framed glasses that took up half of her face, frowned and said, "And then?" ”

Once this happens, the packets can be rerouted though, choosing to transfer to a neighboring node. However, this will cause more nodes to become clogged, and at the very end, cascading failures will be formed. And once this cascading fault contagion occurs, it will be a disaster for the network! ”

Zhou Shuo said, casually pulling out the pencil from her hair. Surprised, she glared at him, but didn't say anything.

I saw Zhou Shuo writing on the paper with a pencil and saying: "In the classical ER and BA models, the average link betweenness of the two is these two formulas. The visible average betweenness only reflects the static nature of the network, and does not reflect the impact of congestion on routing. At this time, the congestion function must be introduced to redefine the routing rules of the packet......"

Hearing this remark, everyone couldn't help but be stunned, if they just thought that Zhou Shuo was a little level just now, now it is the level of shock. I can roughly explain the principle, as long as I have read one or two journals, I am always a little impressed. But if you can come up with a formula while talking about it, you have to study it yourself.

Because the Internet has been around for a short time, all kinds of public research materials are general, such as the two classic models cited by Zhou Shuo, which are the secrets of communication equipment manufacturers. If you can improve it, or even come up with a more efficient model, it will be a proper student.

Director Huang stood aside and asked curiously, "Principal Zhou is so familiar with the knowledge of routing?" ”

Zhou Shuo put the pencil on the table, put his hands in his pockets, looked into the distance, and said silently: "Where, just a little research." ”

In his previous life, the Huaxing Group he worked for was a large group with network communication equipment as its main business direction, and the performance of the routers optimized and designed by him far exceeded that of Tongji.

When he came back to his senses, the entire laboratory was silent, and everyone was watching him silently.

Zhou Shuo coughed embarrassedly, couldn't he be a little pretending to be forced in his heart, everyone is silently despising me?

"Principal Zhou, you see that this is my research topic, can you give some advice?"

A young man suddenly took out a notebook and handed it to Zhou Shuo.

This made everyone wake up as if they had just woken up, and they all squeezed up and said: "Principal Zhou, the generation algorithm of homogeneous topology and heterogeneous topology is about ......"

"President Zhou, how does the nonlinear relationship between capacity and load ......"

Director Huang saw that everyone was really making trouble, so he dragged them over one by one and said angrily: "Why are they so undisciplined, let's talk about it after there is any problem!" ”

Finally, Zhou Shuo's side calmed down, and Director Huang took his hand and said, "Principal Zhou, when do you think we will start working?" The enthusiasm of the comrades is very sufficient! ”

Zhou Shuo smiled bitterly: "You know, I am also ordered to be in danger, and the task of earning foreign exchange from 10 million is not yet visible." The main reason for this visit is to ask Director Huang to recommend someone who can go to the United States with me to see what opportunities can be fought for. ”

"Oh?" Director Huang's eyes lit up, this is an opportunity to go abroad! Hurriedly asked earnestly: "I don't know what Principal Lu Daozhou has for candidates?" Do you think I can do it? ”

"What are the requirements......" Zhou Shuo scratched his head and thought about it, and said: "Good image, good temperament, fluent spoken English, familiar with the specific situation of the 64th Institute, superb personal business, and it is best to have experience in living and working abroad......"

After Zhou Shuo finished speaking, he suddenly found that everyone's eyes were on Yu Qiong. Director Huang smiled and said, "Principal Zhou's request, I'm afraid only Yu Qiong can meet it." ”

Zhou Shuo asked in surprise, "For what?" ”

"President Zhou probably doesn't know what to do, but he came back from studying at Columbia University in the United States! Otherwise, in terms of experience in working and living abroad, she is the only one. ”

"Oh, no wonder!" Zhou Shuo suddenly realized. It seems that Yu Qiong was a publicly-funded international student in the early nineties, so it is no wonder that she became a researcher at a young age in a research institute that attaches great importance to seniority. In these years, even if there is an establishment, scientific research institutes are often unable to retain outstanding overseas talents.

Director Huang lowered his head, stepped forward and asked, "Less, the organization hopes that you can go on a business trip to the United States with President Zhou, what do you think?" ”

Yu Qiong picked up the pencil on the table and pulled her hair back together. Silently glanced at Zhou Shuo, nodded and said, "Okay, I agree." ”

I don't know where she developed this cold character, obviously it is an opportunity for others to go abroad, but when she says it, it is like "bringing a watermelon home", and there is almost no emotional fluctuation.

However, Director Yu was more happy, and it was not easy to go abroad at this time. When my daughter goes out once, she can bring back some American novelties, which are very convenient for her own use or gifts.

"By the way, there's one more thing." Zhou Shuo pulled Director Huang and said: "Since our 64th Institute is in the direction of optoelectronic network communication, can we apply for access to the Internet?" ”

Huang hesitated and said, "This, we also want to." However, now that the state is short of funds, it will definitely not be approved when it is reported. Unless, we can raise the funds to build ourselves. ”

"What if you use a landline line? Carrier modulation and demodulation on a landline so you don't have to add additional lines, right? This is also a common practice in the United States. ”

"It's not impossible, but the long-distance call fee is not cheap, one dollar a minute."

In 1994, the long-distance phone call fee of one dollar per minute. It means that one day after hanging on the Internet, the two researchers' salaries for a month will go in. With the speed of today's Internet, the maximum speed is only 28.9Kbps, and the transmission speed per second is not even more than 4K, and a picture may be 60 yuan away.

Zhou Shuo patted him on the shoulder and said, "Director Huang, don't worry, I will bear the equipment and network fees." In this way, I can learn more about our work when I am abroad, and it is worth paying a little. ”

"Okay, then." Director Huang reluctantly agreed.

In the following time, Zhou Shuo asked Microsoft to send an invitation letter, and rushed to Beijing with Yu Qiong non-stop.

While waiting for a visa at the embassy, he ran to 173 again.

Professor Zhao saw Zhou Shuo, pulled him and asked, "Okay, you kid, when you said that you would put Shao Shiming back after learning the program, what about people now?" ”

Zhou Shuo scratched his head and pretended to be stupid: "Isn't this still learning." ”

"Learn from you, big-headed ghost! It's been more than two months, and I haven't finished learning any program......"

Zhou Shuo tried his best to appease Professor Zhao.

Zhou Shuo said mysteriously: "Professor, are you interested in making China's first mail server?" ”

"Huh?" Sure enough, Professor Zhao was very interested in this topic.

Linked to Zhou Shuo's level of network skills, Professor Zhao's eyes lit up and said, "Do you kid know how to do it?" ”

At this time, China's Internet was completely chaotic, and even the .cn domain name servers had just returned to China from the United States, and there were only more than 20 websites providing services in China, which were basically research projects of scientific and technological workers, and there were no commercial services.

Zhou Shuo nodded and said, "Hehe, it's just a little while." ”

"Okay!" Professor Zhao slapped him on the back, almost knocking him down. He looked at Zhou Shuo with joy and said, "I really don't know where you learned all these skills, there is no such environment in China!" ”

"Hehe, I'm also scared, I can't afford to say that!" Zhou Shuo argued in a hurry.
