Although voting is subjective, it can be regarded as a fair practice. In the end, after voting, the University of California, Johns Hopkins University, Harvard University and Princeton University won and won the auxiliary root server places.

Stanford University gets the main root server, and the UK and continental Europe each get a secondary root server. As for which university to put in the final, they need to decide internally. Japan and Hong Kong Yulin Institute of Technology each get a secondary root server. In the United States, the Massachusetts Institute of Technology, the University of Chicago, the University of California, Harvard University, Johns Hopkins University and Princeton University each got a secondary root server quota.

So far, the initial distribution of the Internet cake has been completed, and Bao Zixuan is very satisfied with the result. Yulin Institute of Technology gets a secondary root server, which is happier than earning 1 billion.

Joe - Douglas continued: "Now that the servers have been identified, the problem is to link them together. Make sure that each secondary 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 will also be put on the agenda, and I hope that Heiyun and IBM will pay attention to this aspect."

There are no more than two ways to connect to the server. In the early days, people would lay lines in the sea to connect, and now there is satellite assistance. The transmission data of the satellite is limited, and it is not suitable for the connection and data transmission between the various servers of the Internet at all.

Seeing that no one was talking, President Reagan said with a smile: "Whether it is the laying of optical fibers, the conversion of interfaces, and the application of servers. Heiyun Group has research and development and participation, Mr. Xiaobao, don't be modest, you can introduce it to everyone. ."

In fact, Reagan was also very helpless. If he wanted to develop the Internet, he had to find a Hong Kong company to participate. Moreover, the opinions given by think tanks and experts, without the participation of the Black Cloud Group, would not have been possible at all. Unless you play hooligans and ignore patent law. But that will damage the national image of the United States, and will not be recognized by mainstream society.

According to the opinions given by experts, if Bao Zixuan is willing, he can create an Internet by himself. Americans must not tolerate similar things happening, which is why the upgrade of the ARPANET is on the agenda.

Hearing President Reagan's name personally, Bao Zixuan knew that he could not shirk. So he stood up and said: "The server is easy to solve. The Black Cloud Group has reached an agreement with Intel, and the two will jointly develop a new industrial computer. The performance is definitely more than three times that of the existing state-of-the-art computer, and the price has hardly increased."

"As for the connection between servers, we need to use submarine cable transmission technology."

"Compared with terrestrial optical cables, submarine optical cables have many advantages: First, laying does not require digging tunnels or using brackets to support, so the investment is low and the construction speed is fast; It is not damaged by the natural environment such as wind and waves and interfered by human production activities, so the cable is safe and stable, with strong anti-interference ability and good confidentiality."

"As for the construction method, the design of the submarine optical cable must ensure that the optical fiber is not affected by external forces and the environment. The basic requirements are: it can adapt to the environment such as submarine pressure, wear, corrosion, and biology; there is a suitable armor layer to prevent fishing reels from trawling, anchors and sharks. When the optical cable is broken, the length of seawater infiltrating into the optical cable is minimized; it can prevent the hydrogen from penetrating into the optical cable from the outside and the hydrogen generated inside; it has a low-resistance remote power supply circuit; Tension; service life is generally required to be more than 25 years."

"Deep sea; the submarine optical cable with a depth of more than 1000 meters adopts a steel-free armored structure, but the structure of the cable core and the strengthening members 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 In addition, two layers of steel tape should be spirally wrapped around the deep-sea optical cable sheath in shark-infested waters, and a polyethylene outer sheath should be extruded."

"Shallow sea; the cable core structure of submarine optical cable is the same as that of deep-sea optical cable within 1000 meters of water depth, but shallow-sea optical cable should be armored with single-layer or double-layer steel wire. The number of armoring layers and the outer diameter of steel wire should be based on the submarine environment, It depends on the water depth, whether it can be buried, fishing, etc.

"At present, Heiyun Group has developed a special construction vessel that can be used for the laying of submarine optical cables. In shallow seas, for example, in the sea area where the water depth is less than 200 meters, the cables are buried, while in the deep sea, they are laid. Hydro-jet burial is the main Burial method."

"There are several rows of water spray holes at the bottom of the buried equipment, which are distributed in parallel on both sides. During operation, each hole sprays a high-pressure water column to the seabed at the same time, and the seabed sediment is washed away 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 gully will be automatically filled by the tide. The burying equipment is towed forward by the construction ship, and various instructions are made through the working cable. Generally, the cable laying machine does not have underwater burying equipment, and relies on the submarine cable. It is laid on the surface of the seabed by its own weight.

"The ship keeps moving forward, and then the underwater robot rushes a ditch, puts the optical cable in, and then uses the underwater robot to flush the sediment back to cover the optical cable, and then keeps moving forward. When it needs to be connected, it is completed on the ship first. Then seal it, and then continue to lay it. All submarine optical cables are optical fibers, and there are very few cables, and all the laying is buried in the soil, that is, use an underwater robot to dig a trench, 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, thereby rushing out of the groove. As for maintenance, there is no maintenance at all. Usually no maintenance is required, only regular maintenance is required. Use an underwater robot to investigate whether the optical cable has dew, and if so, cover it with sediment. In addition, if it is broken, you can use an attenuation detector to measure the specific location, and then go there and fish it up for docking or other methods. Usually, the damaged section is completely cut off and replaced with a new one."

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

Harry Roland didn't expect Bao Zixuan to be so well prepared, but seeing Reagan's expression made him very worried. Mu Xiu will be destroyed by the forest wind, and it is not a good thing to show her sharp edge, especially on this occasion.

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

On the surface, it is a compliment, but what it actually means is self-evident. If you can't even hear this, you may not be able to get out of the United States.

Bao Zixuan: "In terms of servers, Heiyun needs to borrow the latest CPU from Intel. As for optical cables and routers, the Heiyun family is still unable to produce them. After all, the volume is too large. Fortunately, a preliminary agreement has been reached with Motorola, and Heiyun will authorize it. Motorola produces routers and optical cables. The optical fibers and routers in the European and American markets are all produced by Motorola, and Black Cloud is only responsible for markets in other continents.

Hearing this, everyone was relieved. If all Heiyun products were used, the confidentiality requirements would not be met at all. It seems that this kid knows how to make trade-offs, and things are much easier to handle. The supply of chips is still from American companies. As long as they master the core technology, everything else does not matter.

Now everyone casts envious glances at Robert Calvin. Europe and the United States are the big consumers of routers and optical fibers. With such a big pie, the financials must be pretty good; Motorola stock can be bought a little more.

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

"The Computer Association must play a role and do a good job of coordinating the work. The government will also allocate funds for Internet projects. I will see results within two years."

After the meeting, everyone left the White House.

Bao Zixuan personally drove the Harry-Roland couple back to the hotel, which was a respect for the teacher. As for the cooperation with Intel and Motorola, the following people will handle it well.

In the car, Bao Zixuan said apologetically, "Teacher, I made you embarrassed, and the school lost such a precious opportunity."

As the dean of the Department of Computer Science at the Massachusetts Institute of Technology, seeing Stanford University getting the main root server of the Internet; one can imagine the state of his heart.

Although it cannot be said that the opportunity was lost because of helping Yulin Institute of Technology to obtain the auxiliary root server; but it also has a lot to do with the US government and the Computer Association to maintain balance. If Harry Roland hadn't taken the lead at Yulin Institute of Technology, MIT would not have lost so badly, with less than half of the other party's votes.

Harry Roland: "It's okay, it has nothing to do with you. Stanford has developed too fast in recent years, it seems that we need to pay attention to it ~www.mtlnovel.com~ What does it have to do with losing the main root server, as long as the MIT server room is strong enough, Stanford It may not be able to take much advantage. Moreover, the contact with the European server must go through MIT, and it is really uncertain what will happen in the future.

Whether it is comfort or not, this love Bao Zixuan will always be remembered in my heart. At the critical moment, it was really these teachers who supported him. Compared with other people, the friendship between teachers and students was purer.

Remember that if you have any kindness, at least you can't let Harry Roland and his descendants suffer, and you must find opportunities to repay 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, his growth rate is too fast."

Bao Zixuan did not know that President Reagan had begun to attach importance to the Black Cloud Group, and the future development may not be as smooth as before.
