Rebirth of the Tech Madman

The existence of routers is to provide two important mechanisms of routing and forwarding to connect two or more different networks.

Its concept has existed for a long time. For example, it is called an interface information processor in ARPA, and a multifunctional small computer plays this role.

And like Tang Huan, a full-time router launched in the form of a separate mainframe box equipped with several interfaces is still the first in the market.

In fact, this ns router is essentially a computer without input and output devices such as a keyboard, mouse, and monitor. Special chips optimized for routing and forwarding mechanisms.

However, the research and development of routers is by no means just a matter of modifying the existing system of computers, and everything will be fine, such as the support of communication protocols, the algorithm of routing tables, etc., are all groundbreaking projects.

Fortunately, although the current Internet development situation is full of flowers, it is not so complicated that it is impossible to start. As long as Tang Huan finds a suitable entry point, he can join the new gold industry.

...

Seeing that the time was almost up, Tang Huan stepped onto the stage, looked around at the crowd and said with a smile: I guess the concept of a router is much more obscure than that of a personal computer, so before the official introduction, let's chat casually with everyone, what's the problem? , even if it is brought up on the spot.”

Immediately, someone pointed to the Golden Gate Bridge in San Francisco behind Tang Huan and asked, Tang, do you attach great importance to the router product? Set up a company to operate it.

Of course. Tang Huan nodded solemnly, raised his hand and introduced: The CEO of or1d system, in system company, will be held by Robert Metcalf, the founder of 3, he is an expert who really understands computer networks expert.

After Robert Metcalfe smiled, a reporter from a professional computer magazine asked curiously, We all know that the technology and product promoted by 3 is Ethernet. Does that mean that the ns router supports the interconnection between Ethernets? ?”

More than that. Tang Huan explained with an emphasis: To be precise, there is no problem with ns routers supporting tet. But for other network types, such as ibm's token ring network and sf network, as long as the ts router is implemented It also supports the interconnection between them. Moreover, the ns router supports software system upgrade services to adapt to the ever-changing development of network technology.

Tang Huan stretched out two fingers, In my opinion, as long as there is a ts router.

The nodes scattered in universities all over the United States, even those in European universities, can be connected into a resource-sharing whole.

Tang Huan picked up the product manual and shook it again, So far, four versions have been released: v1, v2, v3, and the most stable v4. In 1975, the communication between the two networks was established at Stanford University. In November 1977, the test between the three networks was carried out between the United States, the United Kingdom and Norway. It can be said that all parties have carried out a lot of practical and effective verification work for practical application. ns Based on these foundations, routers support version v4. In addition, Vientiane running on Fangyuan servers and workstations, and those running on Fangyuan personal computers will support v4 at the operating system level this year.

With the vigorous development of the IT industry, there are more and more professional media and reporters.

After hearing Tang Huan mention the operating system, a reporter asked right away: After AT\u0026T was forcibly dismantled by the Department of Justice, as compensation, it got a license to enter the computer field, and it is also developing Operations in this area. For example, the license from Bell Labs has begun to be tightened, prohibiting the use of source code by universities, and even including learning in lectures. As an advanced operating system that also supports multi-tasking and multi-user. Licensing strategy of Vientiane Will it change? In the future, will there be fierce competition in Vientiane?”

We have noticed this situation. As far as I am concerned, I am willing to support free licensing for the purpose of education. But from the perspective of a commercial company, in practice, the situation encountered is more complicated, and careful research is needed .”

Tang Huan replied in a deep voice. As for competition, besides AT\u0026T's official version, there are several other versions including Berkeley's bsd, and I believe more variants will emerge. Therefore, competition is inevitable, but not Not necessarily a competition with AT\u0026T.

Tang, I am using Pacific bbs, exge mail system and other services, and I even play the online game mud of EA from time to time. A reporter who still has a lot of pimples on his face asked enthusiastically, If the whole United States What will it look like if all the networks are connected together? Will the usage fee be reduced? Are these services you are providing profitable?

Thank you for supporting our products. Tang Huan shrugged with a smile, To be honest, I also think that the current method of connecting to the Internet through the telephone public switched network is a bit expensive, but this is limited by objective conditions. I will Let me tell you a business secret, Pacific bbs, exge mail system, and ea's mud are not profitable yet, we are exploring the way for other peers.

Amidst the roar of laughter, Tang Huan continued: I believe that with the interconnection and expansion of various networks, the cost of use will definitely be reduced, and the services that can be provided will also be more diversified, such as bbs and mud. Form a virtual community that is closer to reality.

...

After Tang Huan completed the interesting and detailed communication session, Robert Metcalfe, David Boggs, Radia Perlman and others began to introduce ns routers, a new product that opened the Internet era, from a technical point of view .

The reporters in the audience kept recording. Undoubtedly, these contents will become the most important reports in various professional magazines, and they will cheer for Tang Huan's layout. (To be continued.)
