Bao Zixuan didn't know what happened in Xiangjiang, and he didn't have time to know. He now spends his days in the lab refining his ideas for network switches, and he just wants to finish his thesis on network switches. Even if you can't make a physical object, you have to let people see the feasibility of the plan, and only in this way will everyone recognize his idea and further increase research in this area.

A network switch is a device that expands the network, and can provide more connection ports in the subnetwork to connect more computers. With the development of the communication industry and the advancement of national economic informatization, the network switch market is on a steady upward trend. It has the characteristics of high performance-to-price ratio, 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, there are two types of switches: WAN switches and LAN switches. WAN switches are mainly used in the field of telecommunications to provide a basic platform for communication. LAN switches are used in LAN networks to connect terminal devices, such as PCs and network printers.

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 support for VLANs (virtual local area networks), support for link aggregation, and even firewall functions.

In addition to being able to connect to the same type of network, switches can also interconnect between different types of networks, such as Ethernet and Fast Ethernet. Many of today's switches are capable of providing 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-intensive critical servers.

Bao Zixuan's network switch paper is improving at a speed that is visible to the naked eye every day, and as the feasibility becomes higher and higher, everyone in the lab is shocked.

Professor Clay Freeman said: "I didn't believe there was a genius in the world, but after seeing how you have behaved these days, I realized that I couldn't have been more wrong. It's not that there is no genius, it's just that he's a mediocre person. ”

To be honest, Bao Zixuan really doesn't know how to refute it, could it be that I have traveled back, these are just the most common basic knowledge of the Internet after a few decades, and they are principles that an ordinary middle school student can understand.

Since MIT professors have assigned the name of genius to him, it makes sense to research any product that amazes the world by himself, so why not!

Bao Zixuan: "The main reason is that you helped me lay a good foundation, and my own computer attainments are not low." ”

Clay Freeman: "Knowing that you're comforting me is that any electronics teacher can teach this job. But it's really not okay without your whimsical thinking, but I don't know much about the feelings of large switches and multi-protocol routers. A friend of mine might be able to help, though, but it's a bit of a hassle for him to come over and help. ”

Bao Zixuan: "Professor Clay, as long as you list the name of someone who can help, I will get him at a great cost." ”

Clay Freeman: "Yes, you're super rich. It's really not possible to smash the other party with money, and the so-called trouble is because the other party is a professor at Stanford University. ”

Hearing this, Bao Zixuan was stunned, why would Clay Freeman recommend someone from Stanford. The two universities of Massachusetts Institute of Technology and Stanford have never stopped competing in electronic technology, especially in the field of computers;

Clay Freeman: "I knew you kid was curious, but he's one of the few engineers I've seen who understands and prepares to tackle large switches and multiprotocol routers. ”

Bao Zixuan: "You better tell me who he is! I'm not very familiar with people at Stanford. ”

Clay Freeman: "Leonard Bossak. ”

Hearing this name, Bao Zixuan was immediately pleasantly surprised, and now John Chambers is already working in Black Cloud. How could you forget such an important god!

In December 1984, Cisco Systems was founded in the United States by a faculty couple at Stanford University: Leonard Bossak, director of the Computer Center of the Department of Computer Science, and Santi Lerner, director of the Computer Center of the School of Business. This connected device is considered to be a sign that the connected age has truly arrived. 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 Bossak, a DEC engineer by training, is already a well-known figure in computer and electronic science in the United States, otherwise Stanford, one of the world's top two computer science schools, would not have invited him to be the director of the computer center.

Bao Zixuan: "Then how can I invite him, as long as the money, reputation, and status are capable people, I will not hesitate." ”

Clay Freeman: "He also just came to Stanford to teach, and I heard that he was in love. Now is the time for both career and love, and it may be hopeful to pay a little money for him to come over temporarily to help. ”

Bao Zixuan: "It's okay to have hope, I don't believe that anyone doesn't like money." It's really not okay, can't you even recruit his girlfriend together!"

It has always been Bao Zixuan's character to do what he says, but who to send to convince Leonard Bossack? After thinking about it, he still feels that John Chambers is the most suitable, and his ability is beyond doubt. Another point is that Chambers was able to join Cisco in '91, which would not have been possible without the approval of the founding couple;

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

After hearing Professor Clay Freeman's words, Bao Zixuan suddenly woke up. Yes, this couple, who were able to sell all their shares in their previous lives because they did not agree with the management, are people of character, and their desire for money is never particularly strong.

Bao Zixuan: "It's still thoughtful and thoughtful, otherwise you almost missed a big event." ”

John Chambers was in Detroit watching a new car test when suddenly the phone rang. When he received the call, the other party just said that he should rush to the headquarters of Black Cloud in Cambridge immediately.

Knowing the personality of the boss, he took the nearest plane to Boston after handing over the work to the people below, and as soon as 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 security, and said, "Why did you come and pick me up today?" ”

In fact, within the black clouds, John Chambers and John Howard are known as the double John combination, and they spend a lot of time on business together, but most of them are with Bao Zixuan;

John Howard: "It was arranged by the boss, and we are going to go to California together after you meet the boss." As for the specifics, 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, everything is still waiting to see what Bao Zixuan is saying!

Chambers was taken directly to MIT's Freeman Lab, and looking at the scene in front of him made Chambers feel like he had stepped into a future space-time.

Bao Zixuan: "John, how about it! This is the product we are going to produce in the future, but now the research and development has entered a bottleneck. And this time I called you here to ask you to find a helper, this is his information. ”

After saying that, he handed over Leonard Boss's information to Chambers, and the information can be said to be very detailed. There is an investigation at Stanford University, and of course, there are memories of Bao Zixuan's past life.

John Chambers read the information and said, "What the boss means. ”

Bao Zixuan: "It's best to be able to join Heiyun, but it's really not okay to let him help me complete a large network switch and a multi-protocol router." Anyway, I'm going to meet people this weekend, and I don't care what means I use, I just want the result. ”

Hearing the boss say this, John Chambers knew that Bao Zixuan was serious. This boss can be said to be very generous to his subordinates, and he also knows how to delegate power, but at the critical moment, he is very domineering, and if the task given to you is not completed, then your status will decline in his heart, and it is estimated that it will be difficult to have a large promotion space in the future.
