Chapter 361

Baozixuan didn't know what happened in Xiangjiang and didn't have time to know. He is now constantly improving his network switch in the laboratory every day. He just wants to finish the paper on the network switch. Even if we can't make a real object, we should let people see the feasibility of the scheme. Only in this way can we recognize his idea and further strengthen the research in this area.

Network switch is a device to expand the network, which can provide more connection ports for the sub network in order to connect more computers. With the development of communication industry and the promotion of national economic informatization, the network switch market is rising steadily. It has the characteristics of high performance price ratio, high flexibility, relatively simple and easy to implement. Therefore, Ethernet technology has become the most important LAN networking technology, and network switch has become the most popular switch.

In a broad sense, switches are divided into two types: Wan switches and LAN switches. Wan switches are mainly used in the field of telecommunications and provide a basic communication platform. The LAN switch should be used in the LAN to connect terminal equipment, such as PC and network printer.

The main functions of the switch include physical addressing, network topology, error checking, frame sequence and flow control. At present, the switch also has some new functions, such as VLAN (virtual local area network) support, link aggregation support, and even some have the function of firewall.

In addition to connecting the same type of network, the switch can also play an interconnection role between different types of networks (such as Ethernet and fast Ethernet). Nowadays, many switches can provide high-speed connection ports supporting fast Ethernet or FDDI, which are used to connect other switches in the network or provide additional bandwidth for key servers with large bandwidth consumption.

Baozixuan's network switch papers are improving at a speed visible to the naked eye every day. With the increasing feasibility, everyone in the laboratory is shocked.

Professor clay Freeman said: "I didn't believe there were geniuses in the world, but after seeing your performance these days, I found myself wrong. It's not that there is no genius, but that he is a mediocre person. "

To tell you the truth, baozixuan really doesn't know how to refute it. Can I say that I came back through the Internet? These are just the most common basic knowledge of the Internet after decades, which is a principle that ordinary middle school students can understand.

Since the professors of MIT have assigned him the name of genius, it is reasonable to develop any products that amaze the world. Why not!

Bao Zixuan: "the main reason is that you help me lay a good foundation, and my computer literacy is not low."

Clay Freeman: "I know you are comforting me. Any teacher in electronic technology can teach me this job. But I can't do without your unrestrained ideas. It's just that I don't know much about large switches and multi protocol routers. But a friend of mine may be able to help, but it's a little troublesome to ask him to come and help. "

Bao Zixuan: "Professor clay, as long as you list the names of those who can help, I'll get him at any cost."

Clay Freeman: "yes, your boy is a super rich. It's really not good. You can smash each other with money; The so-called trouble is because the other party is a Stanford professor. "

Hearing this, baozixuan was stunned. How could clay Freeman recommend Stanford people. The competition between MIT and Stanford Universities in electronic technology, especially in computer science, has never stopped; All want to compete for the reputation of the world's first computer University,

Clay Freeman: "I knew your boy would be curious, but he is one of the few engineers I have seen who can understand and prepare to tackle large switches and multi protocol routers."

Bao Zixuan: "you'd better say who he is! I'm not very familiar with people at Stanford. "

Clay Freeman: "Leonard possack."

Hearing this name, baozixuan was surprised. Now John chambers has worked in heiyun. How can you forget such an important god!

In December 1984, Cisco Systems was founded in the United States by a couple of Stanford University Teachers: Leonard posack, director of the computer center of the computer department, and sandy Lerner, director of the computer center of the business school. The couple designed a networking device called "multi protocol router" for the Stanford campus network, Integrate the incompatible computer LAN in the campus to form a unified network. This networking device is considered to be a sign of the real arrival of the networking era. John Chambers joined Cisco in 1991. In 1996, chambers took charge of Cisco. It was chambers who turned Cisco into a dynasty.

Leonard possack, a Dec engineer, is already a well-known figure in computer and Electronic Science in the United States. Otherwise, Stanford, the world's top two school in computer science, would not have invited him as the director of the computer center.

Bao Zixuan: "then how can I invite him? I won't spare money, reputation and status as long as they are capable people."

Clay Freeman: "he just came to Stanford University to teach, and I heard he was in love. Now is the time for both career and love to have a good harvest. It may be promising to pay some money for him to come and help temporarily. "

Bao Zixuan: "if there is hope, I don't believe that some people don't like money. I can't even recruit his girlfriend! "

It has always been the character of baozixuan to do what he says, but who should be sent to persuade Leonard bosack! After thinking about it, I still think John Chambers is the most suitable. There is no doubt about his ability. Another point is that chambers could join Cisco in 1991. Without the recognition of the founders, it would be impossible to achieve; Now it's just for chambers to meet his former boss in advance.

Looking at the expression of baozixuan, clay Freeman said, "it seems that you have thought of what to do, but I remind you. Some people can't only use money, but also need platforms and technical support that they can't refuse. "

When Professor clay Freeman finished, baozixuan suddenly woke up. Yeah! This couple, who were able to sell all their shares in their previous lives because they disagreed with the management concept, is a man of character and will never have a particularly strong desire for money.

Bao Zixuan: "you are considerate, or you will almost miss the big event."

John Chambers was watching the new car test in Detroit when suddenly the phone rang. After receiving the call, the other party just said that he should rush to the black cloud headquarters in Cambridge immediately.

Knowing the boss's character, he handed over his work to the following people and took the nearest plane to Boston. When he got off the plane, he saw where the company's security personnel were waiting for him.

John Chambers saw John Howard, the director of security, and said, "why did you come to pick me up today?"

In fact, in the dark cloud, John Chambers and John Howard are called the double John combination. They spend a lot of time on business together, but most of them are with who baozixuan; It's rare for two people to chat alone.

John Howard: "it's arranged by the boss. After you meet the boss, we'll go to California together. As for the specific situation, I don't know, but the boss has told me that everything will be under your command after arriving in California. "

John Howard's words puzzled chambers. I'd better wait to see baozixuan talking!

Chambers was taken directly to the Freeman Laboratory of MIT. Looking at the scene in front of him, chambers seemed to feel like entering the future time and space.

Bao Zixuan: "John, how's it going! This is the product we are going to produce in the future, but now R & D has entered a bottleneck. And this time I asked you to come here to ask you to find a helper. This is his information. "

Then he handed over Leonard possack's information to chambers, which can be said to be very detailed. There is a survey at Stanford University, including the memory of baozixuan's previous life.

After reading the information, John Chambers said, "what the boss means."

Bao Zixuan: "it's best to join the black cloud. It's really not good. Let him help me complete large-scale network switches and multi protocol routers. In short, I want to meet people this weekend. I don't care what means I use. I just want the result. "

Hearing what the boss said, John Chambers knew that baozixuan was serious. The boss can be said to be very generous and know how to delegate power, but he is very overbearing at the critical moment. If the task assigned to you is not completed, your position will decline in his mind. It is estimated that it is difficult to have a large promotion space in the future.
