Chapter 140 Yang Xinxin's Future Plan

After spending three days in Disneyland, Chen Zishan was finally satisfied. She flew back to China to visit relatives. Zhang Lexing actually wanted to go back with her, but Yang Xinxin told her before coming to the United States that she would go to the headquarters of VisualSystem Group after watching the World Cup. Once, the pigeons have been released for more than a week now. If they just run away from Los Angeles, Yang Xinxin might come to pick them up in person, and Zhang Lexing himself will feel embarrassed.

It was more than 500 kilometers from Los Angeles to San Jose. Zhang Lexing and several bodyguards drove in two cars for more than five hours, and finally arrived in San Jose.Without taking a break, Zhang Lexing first came to Yang Xinxin's office at the headquarters of the VisualSystem Group.

Yang Xinxin's office didn't look much different from before. When Zhang Lexing walked in, Yang Xinxin was sitting on the sofa alone and seemed to be thinking about something. The coffee table in front of the sofa was covered with a large piece of silk. Just look at the silk. It is estimated that there should be a lot of things below the raised part.

Hearing someone coming in, Yang Xinxin stood up and said with a smile: "Brother, you are finally here. I have been waiting for you for more than a week."

"Sister Xin, I'm sorry to keep you waiting." Zhang Lexing apologized.

"Forget it, just come here." Yang Xinxin beckoned: "Brother, come and sit here."

Zhang Lexing nodded, came to the sofa and sat down, Yang Xinxin followed and sat beside him, and massaged Zhang Lexing up and down on his side, making Zhang Lexing a little confused.

"Sister Xin, you are..."

"I heard that you and a little sister traveled a lot in Los Angeles. You must have had a good time." Yang Xinxin teased with a smile.

"Well..." Zhang Lexing smiled awkwardly.

"This is normal. Brother, you are not young anymore. It's time to find someone to have a serious relationship with. By the way, how does that girl look like? She should be very beautiful. When can I bring it to my sister to see?" , don’t be too mysterious.” After saying a few words, Yang Xinxin’s gossip-like nature of a woman broke out, and she began to ask questions: “How tall is that girl? What are her measurements? What’s her personality like?…”

Zhang Lexing couldn't help covering his face, begging for mercy, "Sister Xin, just let me go, I haven't known Zishan for a long time, so I can answer so many of your questions."

"I called Shang Zishan so intimate, and said we haven't known each other for a long time." Yang Xinxin waved her hand and said, "Forget it, I'll let you go today, but next time I have a chance, I must take it She brought it to my sister to see."

"Sister Xin, don't worry, I will definitely bring Zishan here."

Yang Xinxin stood up and walked to the small refrigerator in the office. After walking two steps, she turned around and asked, "Brother, do you want something to drink?"

"No need." Zhang Lexing shook his head.

Yang Xinxin stopped in her tracks, walked back, supported the sofa with one hand, and said, "Brother, in fact, I asked you to come here this time mainly because I want you to give advice."

After finishing speaking, Yang Xinxin grabbed a corner of the silk cloth on the coffee table and pulled it off forcefully, revealing a model.Zhang Lexing stood up and took a closer look. It seemed like a sand table for some kind of planning and design.

"Sister Xin, what is this?" Zhang Lexing was puzzled by the fact that this kind of thing didn't seem to have any direct relationship with the VisualSystem Group.

Yang Xinxin leaned down slightly, looked at the sand table, and then replied: "This is the planning sand table of the VisualSystem San Jose campus, which marks the main layout of the planned new park."

"Look at it," Yang Xinxin pointed to the middle part with his finger, and said, "This is the core area of ​​the entire park. More confidential research and key equipment (such as supercomputers) will be placed here. The level will be the highest."

"Here," Yang Xinxin pointed to the outer area again, and said, "There are conventional research institutions around here. Fifty buildings are planned to be built, 42 of which belong to the VisualSystem San Jose Research Institute, which will be used for employees to carry out various researches. The rest Eight buildings are auxiliary buildings, which are used to provide various services for employees, such as cafeteria, fitness center, laundry room, etc. There will be a large green area between the buildings, and there will be ponds, gardens, outdoor sports fields and so on... …In short, it is necessary to provide employees with a comfortable working environment, create a free working atmosphere, and allow employees to give full play to their sense of innovation. When the park is completed and moved there, the place will be bigger, and there is no need to crowd together like now In the building."

After listening to what Yang Xinxin said, Zhang Lexing imagined the future vision of the VisualSystem San Jose Park in his mind, and couldn't help but think of his domestic industries. If he still builds a similar park, it should be much more comfortable.

"Brother, I still have the planning drawings of the park in my bookcase. I'm interested to take a look. Well, it's in the second bookcase on the right."

Zhang Lexing came to the bookcase on the right, pointed with his finger, and asked, "Is this the only cabinet?"

"Yes, that's it." Yang Xinxin nodded: "The password is 85106"

Zhang Lexing entered the number that Yang Xinxin entered on the password disk, and the second bookcase on the right opened in response. There were indeed a lot of rolled up drawings inside. Zhang Lexing took them out one by one, and the content was quite rich. , including the overall blueprint, park underground pipe network planning, park greening, park road planning, division of functional areas in the park, hydropower design, etc., and even detailed planning for each building. These planning designs are very detailed, but most of them It made Zhang Lexing dizzy, after all, it was something he hadn't touched for a long time.However, the network part in the plan brought back memories of Zhang Lexing's work as a network engineer, and he studied this part very seriously.

Zhang Lexing laid out an overall plan of the park network on his desk, and then waved to Yang Xinxin: "Sister Xin, come here."

"Well, brother, did you find something wrong?" Yang Xinxin got up and walked over, looking at the drawing and asked.

"Look here," Zhang Lexing clicked on the drawing with his hand, and said: "The backbone network of the entire park planned on the drawing uses FDDI (Fiber Distributed Data Interface, the physical structure is two parallel, opposite for reverse transmission The dual-ring structure network, using the timing token transmission protocol), although FDDI is a good choice at present, the transmission distance is long, the speed is not slow, and it is relatively safe, but this thing is not cheap, and it is a shared structure, when the amount of data increases in the future, this backbone will become a bottleneck.”

"Brother, I don't understand the Internet, so what do you think will be better?"

"Use gigabit network." Zhang Lexing said casually.

"Gigabit network? I seem to have heard of it." Yang Xinxin asked suspiciously.

Just now, Zhang Lexing knew something was wrong as soon as the words came out of his mouth. There is no Gigabit network these days, and the [-]M network is just beginning to be popular, so he quickly changed his words: "Gigabit network is the most cutting-edge technology, and it is not yet mature. Just now Just thinking about the network capacity, I made a mistake for a while.”

"Oh, that's right, so what kind of network should I use?" Yang Xinxin didn't doubt him, and fortunately she was a layman in network technology, otherwise Zhang Lexing would not have been fooled so easily.

Zhang Lexing is a little hesitant. In fact, he knows that the future network structure will definitely be the world of optical fiber networks, and there is even a trend of developing to the desktop. The backbone of the park is generally a Gigabit or [-] Gigabit optical fiber backbone. Ethernet, while long-distance transmission generally uses SDH (Synchronous Digital Hierarchy) or even DWDM (Dense Optical Wavelength Division Multiplexing System, the capacity can reach hundreds of G, or even more), and now these popular token ring networks, FDDI Everything has gone to the garbage dump, and even the ATM (Asynchronous Transfer Mode, a network switching protocol, not a bank teller machine), which has just emerged now, will gradually become marginalized by then.I want to use Ethernet technology, but the current Ethernet has just reached [-]M, and the relevant equipment has not been on the market for a long time, and the maturity is not high.

After weighing for a while, Zhang Lexing finally made a decision: "Sister Xin, as far as I know, there is an ATM technology with great potential for development. It should be used as the backbone of the park. As for the lower layer of the backbone, Fast Ethernet technology can be used ( [-]M Ethernet), if you want to know more, you can consult with someone from Cisco, and I believe their network engineers will give more pertinent opinions.”

In fact, in Zhang Lexing's view, the current structure is definitely only a transitional one, but under the current technical conditions, it can be so for the time being. We can only find a way to replace it when the Ethernet technology matures in the future.

Yang Xinxin readily accepted Zhang Lexing's opinion, and took a notebook to write it down.After talking about this matter, Zhang Lexing thought it was over, but he didn't expect that Yang Xinxin would have a bigger surprise in the future.

"Brother, our plan is not limited to the San Jose park, but also plans to build in Redmond and Boston. Redmond is because Microsoft is there, and it has developed for so many years and has a certain research and development force, so A similar park is planned, but the scale will be smaller. Because there are famous universities such as Harvard University and MIT in Boston, the construction of a park can make full use of its outstanding talents, so there will also be a park construction plan. This is the construction plan of VisualSystem Group's three major domestic (referring to the United States) R&D parks in the next few years. In the plan, the future VisualSytstem Group will focus on research and development. While determining the leading position in the operating system and application software, it will also develop in other areas. The research and development projects are not limited to the current operating system and application software. There will be more research directions, and there will even be a large number of basic research. I believe that in a few years, the ratio of patent income to the company's total income will increase significantly..."

"Sister Xin, the distance between these three parks is not close. Have you considered the communication between the parks? Are you planning to pull the optical cable?"

"Fiber optic cable? We have inquired that such long-distance ones are too expensive, so we don't plan to use fiber optic cables, at least not until the cost drops. Currently we plan to use satellite communication. In order to have enough security to travel , we consider preparing to launch a satellite of our own."

"Satellite? Your own satellite?" Zhang Lexing felt a little unbelievable.

Yang Xinxin nodded and said, "That's right, it belongs to our own satellite. We have already contacted Hughes (later renamed Boeing Satellite Systems), and it takes about 5000 yuan to produce a satellite that meets our needs and retains enough margin." 3000 U.S. dollars, the corresponding rocket and launch costs are about 20 million U.S. dollars, plus 6% of insurance and some miscellaneous expenses, 8 million U.S. dollars is enough to send a satellite into the sky. But this is just a small head, building a ground control station And the corresponding satellite communication system requires a relatively large investment, with a preliminary estimate of [-]-[-] million US dollars. We have consulted with relevant experts, and our communication satellites can choose to be positioned on medium-high orbits, and it is best to choose synchronous orbits , so that only one satellite can cover the entire North America and a part of Europe, which can meet our communication needs for a long time. If three satellites are positioned in the same area of ​​​​the synchronous orbit interval, theoretically, it can meet the needs of any location in the world. Communication, then I can use my own satellite to call you brother, but the only disadvantage is that the ground station must be fixed."

Thinking of satellites, Zhang Lexing couldn't help but think of the future hot "Google Earth": "Sister Xin, if a camera is installed on the satellite, wouldn't it be possible to take pictures of the ground?"

"You think beautifully, but experts have said that imaging satellites equipped with cameras generally operate in low-Earth orbit, about 2000 meters above the ground, so that high-quality photos can be taken, and it will not work any higher. "

Only now did Zhang Lexing understand that if he wanted to play "Google Earth", he had to launch another low-earth orbit satellite. Otherwise, he could only buy it from commercial companies that provide satellite photos. This kind of digital earth is not so easy to play with.

"Sister Xin, I heard that the position of the synchronous orbit seems to be quite tight, is it true?"

"Yes, it is said that this is related to the resolution of the ground station antenna, so I thought about whether to send three up first."

"Then why don't you just shoot three stars with one arrow and send all the satellites up at once."

"Nonsense, launching a satellite is not just a joke. It's not something you can send as you want. I have consulted people from Hughes and experts on this matter. They all suggested launching it in three times, and satellite production also requires a certain amount of time." Periodic, so I plan to launch three satellites separately within five years, and then we will be able to guarantee our global communication, so that every week, research institutions in Europe and Asia can maintain regular communication through satellites No more damn overseas phone calls."

Zhang Lexing also felt the same way about the overseas phone call. The situation is even better now. The previous overseas phone calls were really bad. The voice was often loud and quiet. Listen to what the other party is saying clearly, it is better in the Internet age.
