Yaoguang Electronics wants to start making network equipment, although the networking target required by customers is still only limited to the government agencies and units of the Shudu government, Dingtian can be regarded as a large local area network, but this can definitely be regarded as a huge breakthrough.

When looking at Chambers again, Wang Zhengguo must admit that talents are always talents, no matter where he puts them, he can make a big news that makes people jaw-dropping unexpectedly.

If you think about it carefully, God really destined Chambers to be associated with network equipment, even if it is impossible for this person to work in Cisco in the future, but after this thousand changes, he still can't escape his fate after going around a big circle.

In the car leaving from the airport, Chambers was very talkative: "The Shudu government asked Yaoguang to provide a data exchange system that can connect to different computer terminals, which is probably the concept of local area network. ”

The concept of LAN took shape in the early 70s, and then began to be used on a large scale in the market, among which schools and scientific research institutions used the most, and by the 80s, there were thousands of LAN systems in operation in the United States.

Therefore, the concept of LAN has been fully mature in technology, and the introduction to the Republic to solve the data exchange of different computer terminals in the same office building can of course meet some of the needs of the Shudu Municipal Government.

However, according to the requirements put forward by the Shudu Municipal Government, it is necessary to connect the organs, enterprises and institutions in the entire urban area, including the organs and units where the newly established high-tech industrial park is located in the northwest of Shudu City, so as to realize network data transmission within such a huge range, which is not something that LAN technology can meet.

Wang Zhengguo was very worried about this and was a little puzzled: "The Shudu Municipal Government requires that the computers in the entire urban area be interconnected online, covering a radius of more than 20 kilometers, and the number of computers will definitely reach more than 100,000 in the next five years.

As for the shortcomings of LAN technology: coverage and the number of terminals, even after 2000, it cannot be perfectly solved, let alone in terms of the current technology of the 80s, think about it to know what the result is.

LAN has a fixed number of computer terminals limit, in terms of transmission distance, the top of the sky is to cover a few hundred meters, for the Shudu Municipal Government proposed "Shudu computer interconnection plan", a single LAN technology is absolutely impossible to achieve.

Chambers is not an engineer who develops technology, he only knows that the United States has realized the interconnection of different computer terminals, but he is not very clear about the specific limitations of network interconnection technology.

Hearing Wang Zhengguo suddenly say this, he was anxious: "What do you mean, do you mean that the current computer terminal interconnection technology can only support small-scale computer data exchange within a small range, and the technology that can meet the requirements of the Shudu Municipal Government does not exist at present?"

"That's right, the current LAN technology is far from meeting the requirements, this is the architecture of the technology itself is limited, it is destined to be unable to solve the large-scale, large-capacity computer networking needs in the next ten years, as far as I know so far, there is only one way. ”

Speaking of this, someone also laughed, this time Chambers still started the network interconnection device, and it still can't avoid contacting Cisco.

In Silicon Valley, on the west coast of the United States, 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 business school, designed a networking device called a "multi-protocol router" to integrate the incompatible computer LANs on campus to form a unified network, and they established a company called Cisco, whose main business is to engage in the sales and production of the equipment. ”

Cisco is the key to opening large-scale, long-distance computer interconnection, and the current "Shudu computer interconnection plan" is essentially the concept of the Internet.

So, in the early days of Internet technology, was LAN technology still needed?

There is no doubt that in the 80s, in terms of computer networking technology, LAN technology is the most mature and cost-effective product, even Cisco, its initial products are based on LAN technology to play a role, "multi-protocol routers" are connected to many LANs, rather than computer terminals directly connected.

Of course, the technology in Cisco's hands can definitely meet the needs of the "Shudu Computer Interconnection Plan", which does not need to have any doubts.

"Stanford University faculty couple, what you say has a certain credibility, after all, this is the best university in the United States in terms of semiconductors and electronic technology, no one, no matter what kind of technology it develops, I will not have the slightest doubt. ”

Americans' admiration for Stanford University is even greater for Tsinghua University and Peking University, especially when it comes to electronics and semiconductors, which is almost a pilgrimage mentality, and Chambers, as a practitioner in the computer industry, is even more convinced of this.

As for Wang Zhengguo's so-called "multi-protocol router" networking equipment, whether it can meet the needs, Chambers did not think too much, whether the technical problems can be solved, and when the time comes, you will know that it is useless to say more now.

"So, I'm going to fly to the United States next week to have a look, I had planned to introduce LAN technology before, this time it's just one more company, Stanford University and Cisco, okay, I remember. ”

For Chambers at this time, he is the CEO of Yao Optoelectronics, a super giant that monopolizes the PC computer market in a billion-dollar country, although the company's market value is not as large as that of the United States, but in terms of potential and importance, it is far more than the so-called large companies in the United States.

He knows very well that with the policy of reform and opening up of the Republic and the sustained rapid economic growth, in the next ten years, Yaoguang Electronics will become a world-class company, and it is a major opportunity for professional CEOs to lead such a company to develop from small to large.

So Wang Zhengguo was very relieved, because he understood that it was absolutely impossible for Chambers to leave Yaoguang Electronics at this time and go to work at Cisco, which had just been established for less than a year.

Chambers was able to work at Cisco in 90 years, the first reason was that he was unemployed, and secondly, Cisco at that time had begun to take shape, the physique of the industry giant had already taken shape, and the founder of Cisco left in 90, and there was a vacancy in the company's top management, which gave Chambers the opportunity to take advantage of the vacancy.

If it is only 85 years old, Cisco is still a typical start-up company, neither getting any investment, nor showing signs of industry hegemony.
