"Hey, Jeff, hand me the papers!"

"Hey, Jeff, I've got this line of code over to you, I'll go to the bathroom. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo”

Although the decoration of an office of Cisco Systems is very simple, the desks and computers are all high-end configurations, and the working environment of a team of seven or eight people is very comfortable for Jeff Bezos, who has just found his first job.

Sipping free black coffee, tasting the free lunch meal and fruit, typing your favorite code, and experiencing the mutual help and friendship between colleagues, this is simply paradise!

I've been working for a while, and thanks to his Princeton University degree and excellent grades, Bezos was fortunate enough to join Cisco in the development of a new project.

Switch, that's the name proposed by the Minister of Technology, Leonardo Bossak, but as he recounted the specific features of this instrument, Bezos keenly perceived from the details of his words that it did not seem to be the brainchild of Bossak himself. But since the leader didn't explain anything, of course he didn't care.

In fact, for Bezos, whether it is Cisco's current flagship product router, or the so-called switch that Bosak is now starting to study, it is a very magical new thing. During his four-year college career, Bezos studied computer science, but the products he came to produce by this company were something that had never been seen in the industry. It can be said that he is absolutely motivated from all angles, and now that he has joined the research group of the switch, his enthusiasm for his work is simply beyond everyone!

However, both Bezos and his colleagues quickly discovered that many of the manufacturing steps in the current router space would have to be modified if the planned switch was to be made.

As for the difference between routers and switches, and what kind of technology do new products need to have...... Posak has provided information.

This is something that surprises Bezos very much, and it is also very confusing. Because practice has proved that Bosak does not know anything more than the rest of them, and everyone is on the same starting line. But he just came up with a very detailed and crucial document, which gave a detailed explanation of what technology the switch needs to use, what technology is like, and even compared it with the router, which is incredible.

However, since 80% of the company's employees were recruited quickly in a few months, everyone did not ask Bosak in detail for the time being.

To say exactly what a switch should look like, you must first understand the characteristics of a router.

First of all, the router is a third-layer network device, and the so-called third-layer is actually a definition made by the document that integrates the functions of the switch. The first layer of network equipment is the hub, which belongs to the physical layer, has no data processing capabilities, and its function is simply to send current to other ports, and the second layer is the switch that everyone is currently studying, which should be able to distinguish the details of the MAC source and destination addresses, that is, the physical hardware address, and then establish a connection between any two ports. After that, there is the third layer, where the router is responsible for resolving the IP address in the data.

Secondly, it can connect to different types of networks, which is also the original intention of the router development. The router is capable of connecting different types of LAN and WAN, such as Ethernet, ATM, FDDI, Token Ring, etc. Different types of networks transmit different data units, frames, in different formats and sizes, just as road transport is loaded with goods in units of cars, while railway transport is loaded with goods in wagons. When data is transferred from one type of network to another, a frame format conversion is required.

Finally, the router also has a path selection feature. Because in the network, there may be many paths from one node to another, and the router can choose a smooth and fast short circuit, which greatly improves the communication speed, reduces the communication load of the network system, and saves network system resources.

It's fair to say that after initially learning what Cisco was producing, Bezos couldn't help but get excited. As he sees from time to time, all employees in the entire company are working hard all the time, and working overtime until 10 o'clock at night is completely normal.

Because the products they are producing are the treasures that can cause the development of the global network!

As for the idea of the switch......

According to the idea provided in the document, there are two types of switches, namely Ethernet switches on Layer 2 networks and node switches on Layer 3. Used to expand the LAN, the working principle is relatively simple, that is, according to the MAC address addressing, and then select the route through the station table, as for the establishment and maintenance of the station table, it is carried out by the switch, but it is also fully automatic.

Undoubtedly, this so-called Ethernet switch will be the company's most mainstream product. The difference between it and the so-called node switch is that the node switch works on the WAN, while the Ethernet switch works on the LAN. The second is that the node switch is used to store and forward data packets, with built-in forwarding tables, which implements the routing protocol and is the node in the network topology; the Ethernet switch is used to connect the host inside the LAN, there is no forwarding table inside, only the MAC address and the mapping table of the host, and it is logically a bus structure.

In a word...... It's complicated.

This was Bezos's first thought after reading the document.

And he is really curious, the company has not even appeared in the trial works, why can Bosak come up with such systematic information?

"Donko, I'm going to the bathroom, don't stop me, I've been doing it here for five hours in a row. ”

Working from midnight to early in the morning, with a table full of disposable paper cups for coffee and two dark circles under his eyes, Bezos yawned and walked into the hallway, and ran into the bathroom with a cigarette.

Bezos, of course, doesn't know the company's finances, but it can be seen that the profitability is really not ordinarily good, at least from the decoration of the bathroom. The bright copper faucet and the high-end brand sink, I don't know that the perfume placed there still exudes a charming smell, and if you add a little soft music, it looks like a high-end hotel at all.

This was not something that the Bosses could have devised it, and Bezos could have guessed it even if he was stupid. A marketing minister and a technical minister, they are all typical pedantic people, and for the same amount of money, of course, they will spend it on buying more equipment, rather than doing small things like decorating the bathroom.

So, after thinking through the structure of the entire company, Bezos happily realized, I'm afraid that only the chairman who has never shown up would think so, right?

In other words, what is the name of the chairman?

After patronizing the research and development of new projects all day long, Bezos suddenly realized that he had forgotten such an important thing.

After using the bathroom, he wandered around the hallway. Indeed, it was about ten o'clock in the morning, and it should have been the beginning of the day. However, companies in the IT industry can't be viewed with common sense, from last night after work until late at night, after a break, and from 5 o'clock in the morning to now, can't people rest and rest?

"Ah~ I'm tired, isn't it better to have another drink when I go back?"

Even though he was a little confused for his walk, Bezos didn't pay attention to where he was heading, and his mind was full of thoughts about another cup of coffee. When he finally came back to his senses in a trance, he realized that before he knew it, he had walked to the door of the CEO's office printed on it.

Well, the chairman is the CEO, and the company is not too big to be too complicated, but the small print under the name plate is also talked about by many colleagues, and they wonder who the boss of their own company is.

Under the big golden words of "CEO", the handwriting in a line of flowers is very delicate, but the content of the words is not polite at all.

“i-am-ceo，bitch！”

Seeing it, the boss has a lot of personality, so it's no wonder he doesn't go to work all day.

"What's wrong with not going to work? Lao Tzu is the CEO, who dares to say anything!?"

As soon as Bezos finished speaking, the door suddenly opened.

Suddenly, it opened.

Then it opened.

It's on.

Finish.

Bezos's whole body was in a cold sweat that was really flowing down without money......

However, when he looked at the figure at the door, he was immediately dumbfounded. (To be continued.) )
