Reborn in Hong Kong: The Tycoon Grows Up

Although voting is subjective, it is still a fair practice. After the final vote, the University of California, Johns Hopkins University, Harvard University and Princeton University won and got the auxiliary root server quota.

Stanford University will get the main root server, and the UK and Continental Europe will each get a secondary root server. As for which university will be placed in the end, they need to make an internal decision. Japan and Xiangjiang Yulin Institute of Technology each received a secondary root server. In the United States, MIT, the University of Chicago, the University of California, Harvard University, Johns Hopkins University, and Princeton University each received a auxiliary root server quota.

At this point, the Internet cake has been initially distributed, and Bao Zixuan is very satisfied with the result. Yulin Institute of Technology is happier than making 1 billion yuan by getting a secondary root server.

Joe Douglas continued: "Now that the servers have been determined, the problem now is to link them together. We must ensure that each auxiliary root server can connect to the main root server. Only in this way can global interoperability be achieved."

"At the same time, a new generation of industrial computers must also be put on the agenda. I hope Heiyun and IBM can pay attention to this aspect."

There are two ways to connect to the server. In the early days, people would lay lines in the sea to connect. Now there is satellite assistance. However, the transmission data of satellites is limited and is not suitable for connections and data transmission between various servers on the Internet.

Seeing that everyone was silent, President Reagan said with a smile: "Whether it is the laying of optical fiber, the conversion of interfaces, or server applications. Heiyun Group has R\u0026D and participation. Mr. Xiaobao, please don't be modest. I can introduce it to you." .”

In fact, Reagan was also very helpless. If he wanted to develop the Internet, he actually had to find a Hong Kong company to participate. Moreover, according to the opinions given by think tanks and experts, without the participation of Heiyun Group, the matter would not be possible at all. Unless you are acting rogue and don't care about patent laws. But that would damage the national image of the United States and would not be recognized by mainstream society.

The advice given by experts is that if Bao Zixuan is willing, he can create an Internet by himself. The Americans would never tolerate similar things happening, so they put the ARPANET upgrade on the agenda.

When President Reagan personally named him, Bao Zixuan knew he couldn't shirk it. So he stood up and said: "Servers are easy to solve. Heiyun Group has reached an agreement with Intel. The two companies will jointly develop new industrial computers. The performance is definitely more than three times that of the most advanced computers currently available, and the price has almost no increase."

"As for the connection problem between servers, submarine optical cable transmission technology needs to be used."

"Compared with terrestrial optical cables, submarine optical cables have many advantages: First, laying does not require digging tunnels or supporting brackets, so investment is low and construction speed is fast; second, except for landing areas, most cables are on the seabed at a certain depth. It is not affected by the damage of the natural environment such as wind and waves and the interference of human production activities. Therefore, the cable is safe and stable, has strong anti-interference ability and has good confidentiality performance."

"As for the construction method, the design of submarine optical cable must ensure that the optical fiber is not affected by external forces and the environment. Its basic requirements are: it can adapt to submarine pressure, wear, corrosion, biological and other environments; it has a suitable armor layer to prevent fishing trawls, anchors and sharks damage; when the optical cable breaks, minimize the length of seawater penetrating into the optical cable; prevent hydrogen from penetrating into the optical cable from the outside and prevent hydrogen from being generated internally; have a low-resistance remote power supply circuit; be able to withstand the stress during laying and recycling Tension; service life is generally required to be more than 25 years."

"Deep sea; submarine optical cables with a depth of more than 1,000 meters adopt a steel-free armored structure, but the structure and reinforcing components of the optical cable core must be able to protect the optical fiber to prevent the high pressure of seawater and the high tension during laying and recycling. In order to prevent shark damage , two layers of steel tape should also be spirally wrapped around the sheath of deep-sea optical cables in shark-infested waters, and a layer of polyethylene outer sheath should be squeezed."

"Shallow sea; the core structure of submarine optical cables with water depths within 1,000 meters is the same as that of deep-sea optical cables, but shallow-sea optical cables must have single or double layers of steel wire armor. The number of armor layers and the outer diameter of the steel wires should be based on the submarine environment and the route of the submarine cable. It depends on the water depth, whether it can be buried, fishing, etc.”

"At present, Heiyun Group has developed a special construction ship that can be used for laying submarine optical cables. In shallow seas, such as sea areas with water depths less than 200 meters, cables are buried, while in deep seas they are laid. Hydrojet burial is the main method Burial method.”

"There are several rows of water spray holes at the bottom of the buried equipment, distributed in parallel on both sides. During operation, each hole sprays high-pressure water columns to the seabed at the same time, washing away the sediment on the seabed to form a submarine cable trench; there is a fairlead on the upper part of the equipment , used to guide the optical cable to the bottom of the submarine cable trench, and the trench will be automatically filled by the current. The burial equipment is towed forward by the construction ship, and various instructions are given through the working cable. The cable laying machine generally does not have underwater burial equipment and relies on the submarine cable The dead weight is laid on the seabed surface.”

"The ship keeps moving forward, then uses the underwater robot to dig a ditch and put the optical cable in. Then the underwater robot washes back the sand and covers the optical cable, and then keeps moving forward. When it needs to be connected, it is completed on the ship first. Then it is sealed and laid again. All submarine optical cables are optical fiber. There are very few cables, and all the ones laid are buried in the soil. They use underwater robots to dig a trench and put it in and then bury it in the soil. "

"As for the underwater robot, it actually uses a high-pressure water pump to pressurize the water to a very high pressure and spray it out, so as to rush out of the trench. As for maintenance, there is no maintenance at all. It usually does not require maintenance and only needs regular maintenance. Just use an underwater robot to check whether the optical cable is exposed, and if so, cover it with sediment. In addition, if it is broken, use an attenuation detector to measure it to get the specific location, and then go there and fish it up for connection or other methods. Usually the damaged section is completely cut off and replaced with a new section.”

After Bao Zixuan finished speaking, not only President Reagan, but also the experts in the computer field present were dumbfounded. It turns out that this kid has taken everything into consideration, and it is really impossible not to play with others.

Harry Roland didn't expect Bao Zixuan to be so well prepared. Seeing Reagan's expression made him very worried. Everything that is beautiful in the forest will be destroyed by the wind. It is not a good thing to show your sharpness, especially in this situation.

Joe Douglas knew that Reagan didn't understand technology, so he was the only one who could speak at this time. So he said: "Mr. Bao is really well prepared. He can be said to be a hero. Servers, routers, submarine optical cables and construction ships can all be solved. It seems that the Internet plan can be implemented immediately."

It's a compliment on the surface, but what it actually means is self-evident. If you can't even hear this, you may not be able to leave the United States.

Bao Zixuan: "As for servers, Heiyun needs to borrow Intel's latest CPUs. As for optical cables and routers, Heiyun cannot currently produce them. After all, they are too big. Fortunately, a preliminary agreement has been reached with Motorola, and Heiyun will authorize them. Motorola produces routers and optical cables. All optical fibers and routers in the European and American markets are produced by Motorola, and Heiyun is only responsible for the markets in other continents."

Everyone was relieved after hearing this. If all Heiyun products were used, confidentiality requirements would not be met at all. It seems that this kid knows how to make choices, and things will be much easier to handle. Chip suppliers are still all American companies. As long as they master the core technology, the rest doesn't matter.

Now everyone looks at Robert Calvin with envy. Europe and the United States are the major consumers of routers and fiber optics. If you get such a big piece of cake, the financial data must be very beautiful; you can buy more Motorola stock.

Reagan: "Now that the servers and construction methods are available, let's get started on the Internet plan!"

"The Computing Machinery Association must play its role and do a good job in coordinating the work. The government will also allocate funds for Internet projects. I want to see the results within two years."

After the meeting, everyone left the White House.

Bao Zixuan personally drove Harry and Rowland back to the hotel as a sign of respect for the teacher. As for cooperation with Intel and Motorola, the people below will take care of it.

In the car, Bao Zixuan said apologetically: "Teacher, I have put you in a difficult position and caused the school to lose such a precious opportunity."

As the head of the Department of Computer Science at the Massachusetts Institute of Technology, you can imagine what your heart will be like when you see Stanford University getting the main root server of the Internet.

Although it cannot be said that the opportunity was lost because of helping Yulin Institute of Technology obtain the auxiliary root server; it also has a lot to do with maintaining a balance between the US government and the Computer Association. If Harry Rowland had not taken the lead in taking a stand on Yulin Institute of Technology, MIT would not have lost so embarrassingly, with less than half of the votes of the other party.

Harry Rowland: "It's okay, it has nothing to do with you. Stanford has grown too fast in recent years, and it seems it needs to pay more attention to it. What does it have to do with losing the main root server? As long as the MIT computer room server is powerful enough, Stanford may not be able to take up much of it. It’s cheap. Moreover, contacts for European servers must go through MIT, so I really can’t say what the future will hold.”

Regardless of whether it is comfort or not, Bao Zixuan will always remember this love in his heart. At the critical moment, these teachers really support him. Compared with others, the friendship between teachers and students will be purer.

If you are kind, you must remember that at least you must not let Harry Rowland and his descendants suffer, and you must find opportunities to repay him in the future.

After experts in the computer field, well-known professors, and heads of major companies left, Reagan said to his assistant: "Pay attention to Heiyun Group and Bao Zixuan. They are growing too fast."

Bao Zixuan didn't know that President Reagan had begun to pay attention to Heiyun Group, and its future development might not be as smooth as before.
