Chapter 361： Last Campus Life - Network Switch

Bao Zixuan didn't know what happened in Xiangjiang, and he didn't have time to know. He is now constantly improving his network switch ideas in the laboratory every day, and he only wants to complete the thesis on network switches. Even if there is no real object, people must see the feasibility of the plan. Only in this way will everyone recognize his vision and further increase research efforts in this area.

A network switch is a device for expanding the network, which can provide more connection ports in the sub-network to connect more computers. With the development of the communication industry and the advancement of the informatization of the national economy, the network switch market has shown a steady upward trend. It has the characteristics of high cost performance, high flexibility, relative simplicity, and easy implementation. Therefore, Ethernet technology has become the most important LAN networking technology today, and network switches have become the most popular switches.

Broadly speaking, switches are divided into two types: WAN switches and LAN switches. WAN switches are mainly used in the telecommunications field to provide a basic communication platform. The local area network switch is used in the local area network to connect terminal devices, such as PCs and network printers.

The main functions of a switch include physical addressing, network topology, error checking, frame sequence, and flow control. At present, the switch also has some new functions, such as support for pairing, support for link aggregation, and some even have the function of firewall.

In addition to being able to connect networks of the same type, switches can also interconnect different types of networks. Many switches today offer high-speed connectivity ports that support Fast Ethernet or FDDI, etc., to connect to other switches in the network or to provide additional bandwidth for bandwidth-hungry critical servers.

Bao Zixuan's paper on network switches is improving at a speed visible to the naked eye every day. As the feasibility becomes higher and higher, everyone in the laboratory is shocked.

Professor Clay-Freeman said: "I didn't believe that there were geniuses in this world, but after seeing your performance these days, I found that I was extremely wrong. It's not that I don't have a genius, I'm just a mediocre person."

To be honest, Bao Zixuan really doesn't know how to refute it. Could it be that I came back from time travel? After a few decades, these are just the most common basic knowledge on the Internet, and it is the principle that an ordinary middle school student can understand.

Since all MIT professors have assigned him the title of genius, it is reasonable to develop any products that amaze the world by himself, so why not do it!

Bao Zixuan: "The main reason is that you have helped me build a good foundation, and also that I am not low-level in computer skills."

Clay Freeman: "Knowing that you comfort me, any teacher in electronic technology can teach this job. But without your imaginative ideas, I really can't do it. It's just that I don't have feelings for large switches and multi-protocol routers. Understandable. But a friend of mine might be able to help, it's just a bit of a hassle to have him come over to help."

Bao Zixuan: "Professor Klay, as long as you list the name of someone who can help, I will get him no matter how expensive it is."

Clay Freeman: "Yeah, you're a super rich kid. You can throw money at the other party; the so-called trouble is because the other party is a professor at Stanford University."

Hearing this, Bao Zixuan was taken aback, why would Clay Freeman recommend someone from Stanford? The competition between the two universities of MIT and Stanford in electronic technology, especially in computing, has never stopped; both want to compete for the reputation of the world's first computer professional university,

Clay Freeman: "I knew you kid would be curious, but he's one of the few engineers I've met who understands and prepares to tackle large switches and multi-protocol routers."

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

Clay Freeman: "Leonard Posack."

Hearing the name, Bao Zixuan was immediately pleasantly surprised. Now John Chambers is working at Heiyun. How could such an important God be forgotten!

In December 1984, Cisco Systems was established in the United States. The founders were a couple of faculty members at Stanford University: Leonard Posak, director of the Computer Center of the Department of Computer Science, and Santi Lerner, director of the Computer Center of the School of Business, The couple designed networking devices called "multi-protocol routers" for the Stanford campus network to bring together incompatible computer LANs on campus into a unified network. This connected device is considered to be a sign that the Internet age is truly coming. John Chambers joined Cisco in 1991, and in 1996, Chambers took the helm of Cisco, and it was Chambers who turned Cisco into a dynasty.

Leonard Bosack, who was born as 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 to be the director of the computer center .

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

Clay Freeman: "He also just came to Stanford University to teach not long ago, and I heard that he is still in love. Now is the time for both career and love to be harvested. There may be hope for him to help him temporarily with some expenses."

Bao Zixuan: "It's okay if there is hope. I don't believe that there are people who don't like money. It's really impossible to recruit his girlfriend together!"

It has always been Bao Zixuan's character to do what he says, but who should he send to persuade Leonard Bosack! After thinking about it, I still think that John Chambers is the most suitable, his ability is beyond doubt. Another point is that Chambers could join Cisco in 1991, which would not have been possible without the approval of the founder couple; now it is just a meeting between Chambers and the former boss in advance.

Looking at Bao Zixuan's expression, Clay Freeman said: "It seems that you have already thought about what to do, but I remind you. Some people can't just use money, but also need to use platforms and technical support that he can't refuse. ."

Hearing Professor Clay-Freeman finish speaking, Bao Zixuan suddenly woke up. Yes! The couple who were able to sell all the shares in their previous life because they were not in line with the management philosophy were people of character, and their desire for money would never be particularly strong.

Bao Zixuan: "It's still as thoughtful as you think, or else you've almost missed a major event."

John Chambers was watching a new car test in Detroit when the phone rang. When he received the call, the other party just said something and asked him to rush to the Black Cloud headquarters in Cambridge immediately.

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

John Chambers saw John Howard, the head of the security department, and said, "Why are you here to pick me up today?"

In fact, in the black cloud, John Chambers and John Howard are known as the Double John combination They spend a lot of time together on business trips, but most of them are with Bao Zixuan; Rarely.

John Howard: "It was arranged by the boss. After you and the boss meet, we will go to California together. As for the specific situation, I don't know, but the boss has already explained that everything will be under your command after arriving in California."

John Howard's words made Chambers a little confused, so let's wait until he sees what Bao Zixuan is talking about!

Chambers was taken directly to MIT's Freeman Laboratory, and looking at the scene in front of him made Chambers feel as if he had entered a future time and space.

Bao Zixuan: "John, how is it! This is a product we plan to produce in the future, but now the research and development has reached a bottleneck. And this time I asked you to come here because I want you to find a helper. This is his information."

After he finished speaking, he handed over Leonard-Bosac's information to Chambers. The information can be said to be very detailed. There are investigations at Stanford University, of course, including the memories of Bao Zixuan's previous life.

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

Bao Zixuan: "It's best to join Heiyun. I really can't ask him to help me complete a large network switch and a multi-protocol router. Anyway, I want to meet people this weekend. As for the means, I don't care, I just want the result."

Hearing what the boss said, John Chambers knew that Bao Zixuan was serious. This boss can be said to be very generous to his opponents and knows how to delegate power, but he is very domineering at critical moments. If the task given to you is not completed, your status in his heart will decline. It is estimated that it will be difficult to have a large room for promotion in the future. .
