Since both parties knew the purpose of the meeting, after a brief exchange of pleasantries, Mr. and Mrs. Bossak immediately led Alice and her family to their office. Pen ~ fun ~ pavilion www.biquge.info

On the way there, Bosak explained their own situation, after all, it was the first time they had seen James.

"My husband and I used to belong to different departments of the computer department, and when we contacted each other, we found that without a device like a router, it was too cumbersome for computers to communicate between different networks by email alone. So a long time ago, we started working on this project, but we didn't expect to be preempted by Alice! ”

No matter how Santi talked in a high tone, James listened very indifferently, Alice looked at her family, very good, no one showed a particularly happy and unacceptable appearance, which gave her face.

It's just that Hannah is a little special, always looking at the couple's formal clothes. When everyone passed a corner, she tugged at Alice's clothes and said, "It's not going to the restaurant for a banquet, why are they wearing so good?" ”

Alice also has this question in her heart, after all, everyone knows what the life style of Silicon Valley workers is, and it is too awkward to see people like Posack actually wearing a BOSS suit, and Santi changing into a new Chanel suit this year.

"I'm sorry, the work area is always so messy, just pay attention to your step, it doesn't matter what is on the table."

Soon, Mr. and Mrs. Bossak ushered everyone into the school building and into a small office.

It was full of electronic components, or paper papers piled up to the ceiling, but as soon as Alice stepped inside, she noticed a young man sitting in the corner with his head up, reading something carefully.

"I'll introduce you."

Coming here, the home game is Posack himself, not Santi: "Bill? Hey, Bill! ”

Seeing the young man look up blankly, Posack said, "This is a colleague from the same group as me, Bill Ig, who has studied information technology very well. Bill, this is ......"

"You're Alice-Wang?"

Alice once again keenly noticed that this man was just like Chen Jingrun, who seemed to be wandering all the time, and his speech was even more light: "That genius girl who invented that cheap and cheap and small device that can connect to different networks one step ahead of us? ”

Alice: "............"

Oscar read Iggy's sentence lightly and muttered, "It's such a long sentence, why doesn't he fill in a few more sentences?" ”

Because most of Frankenstein's talents are like this, just look at the future American drama "Scorpio Network".

With a secret smile in her heart, Alice greeted Eagle in a proper manner.

Although I don't know what the hell this benevolent brother is, he really fits the image that Alice should have in her mind, a technical geek: thick-rimmed glasses, hair that hasn't been washed for a week, stubble, and raunchy clothes that smell sour, etc., are much more qualified than the Bossaks at this time.

"Oscar, Hannah, you two just sit there, be obedient and don't touch anything."

Sophie hurriedly arranged the two children, although she is not an expert, but in the face of this kind of thing, of course she and James must be present. Mr. and Mrs. Posack and Iggy got busy preparing for Alice's router function check.

"The case of the instrument is excellent, the texture is good, and the matte texture is ......"

While busy preparing for the scene, Eagle kept talking to himself, speaking lightly in a distracted tone, and looked and stroked the dark shell of the router from time to time: "Are you looking for a product made by a small factory?" Miss Wang? ”

"Just call me Alice, that ...... Leon? ”

Without answering Iggy's question, Alice whispered to Bossak, "Is this Iggy really capable?" Are you going to get him to join our group? ”

"Of course, Iggy is almost a pioneer in the field of computer information and communication, and although you developed the router before us, he ......"

Bossake's voice was not low at all, and while plugging the computer cable into the router, he said in a loud voice: "Iggy, show your work to Alice first, I guess her eyes will be like bullfrogs!" ”

"Oh, okay."

Still in the same tone as if he wasn't in this world, Eagle said softly, pulling out another rough-shaped metal box from somewhere.

"Alice, this is my Jerry, it's designed to be the same as your router, but it's still a half-finished ......"

As soon as she saw that Eagle actually took out such an instrument, Alice still had the energy to think about other things, so she rushed to him in one step and took the box over.

How about this semi-finished product!?

Of course, Alice is a hundred assured of her product, although it is limited to the times, many functions are not yet used, but in terms of programming skills, it is definitely Windows-95 level!

But it's a competitor's thing!

"There's no utility yet, I'm still programming it."

Iggy's words made Alice's heart fall suddenly, and he then asked, "By the way, you named your instrument Router, is that a nickname or the name of a product?" ”

"Of course it's the name of the product, hey, the nickname is ......"

"Oh, Alice, you know, I have a lot of colleagues who like to give their products ......"

"Ahem, Bill, why don't you listen to Alice first, she's already made the finished product."

"Oh, okay......"

It's still the kind of light and fluttering, as if you've been dreaming......

Oscar and Hannah have been sitting in the corner, but they don't feel bored at all. After all, this is an office in the computer science department of Stanford University, and both the meaning of the term itself and the stacks of documents around it are enough to raise the interest of the two of them.

James and Sophie, of course, don't understand the technical level, but watching Alice and Posack and the others gather in front of a pile of computers, of course they have to straighten their necks to observe the situation.

"Let's give you a brief introduction to my design idea, here's how it works, Iggy."

The computer was connected, but Alice didn't rush to do it, but first drew on a piece of paper.

"First of all, the word route itself doesn't mean a route, a road. The basic function of a router is to transmit information from the source through the network to the destination...... Hey, Oscar, Hannah, don't patronize and play, Teacher Alice is teaching you for free! ”

"Okay sister!"

"Cut, annoying!"

"The process of routing consists of two basic actions, determining the best path and transmitting information over the network. In this process, the latter is also known as data exchange, and the exchange is relatively simple, while the choice of path is complicated, right, Iger? ”

Eagle nodded, "That's right, that's the difficulty I'm currently overcoming. ”

"As for the routing algorithm, I just use the decimal method to determine the measurement criteria for the best path to the destination, such as the length of the path. Here, we also need to use a program called a routing table, I don't know if you've made it this far, anyway, I've written a copy, and I'll show you later, it's stored on a router or networked computer, and it has a path to a specific network address. ”

So, of course, every networked router is both a provider and a receiver of information. The routing algorithm populates the routing table based on a lot of information, and the so-called routing is the best way to tell the router to reach the destination by the destination address pair. Specifically, the destination router sends packets of information to the host, and when the host receives a packet, it checks its destination address and tries to contact it. ”

Looking at Iggy's pensive appearance, Alice kept continuing: "As for the exchange algorithm, it is relatively simple. First of all, we need to set up the routing protocol, that is, the heterogeneous network interconnection mechanism. When packets from one network are sent to another, the router directs the path information for the IP packets to send. The so-called agreement is the pre-agreed rules and standards in the process. ”

"Then, it's based on that protocol that the data is exchanged, and the data exchange is based on path selection. This is the best way to transfer information between different networks! ”

"Well, Oscar, Hannah, how much do you understand?"

Finally, Alice looks at her younger siblings in the corner.

Of course, Alice didn't know how far the Bossaks had studied, so at least half of her explanation just now was for the surrounding family. After all, although they built this car behind closed doors, it was only a week before and after, and the so-called router is a magic thing, they can understand a ghost!

But, despite her own explanations, Alice smiled wryly and realized that Hannah's eyes had long since been replaced by a string of mosquito coils.

And Oscar kept scratching his head and said slowly: "That routing algorithm or something, path selection or something, it's all a college math course, right?" ”

There was a flurry of laughter in the office, and Posack laughed, "That's right, that's right, if you want to make a big career in the field of programming, you must excel in mathematics!" ”

"Uh...... I hate math ......"

For the rest of the afternoon, Alice never stepped out of the office again, and in addition to simply experimenting with various types of network interconnection, she had to answer various design ideas to the three experts, especially Iggy's repeated questions.

It was only half an hour before Hannah dragged Sophie and asked her to accompany her to the campus for a walk. Oscar was very interested in these experiments, and listened with wide eyes as he patiently accompanied James.

"So, the efficiency of a router is closely related to the CPU it uses, which is the largest part of the cost. Look at Intel's latest one, $320, I bet you, it doesn't cost even ten dollars! ”

When she said this, Alice was really unambiguous. She knows very well that when Jobs first founded Apple, in the face of Intel's CPU of about 300 dollars, he cut the price to 75!

Three hundred, seventy-five, and Intel can still make money, super profiteering!

Gradually, the sky outside the window has been shrouded in twilight, and the orange light is all over the land, but there are only a few more students on campus, maybe it is dinner time.

"This is huge profits, otherwise, how can Intel become one of the world's top 100 companies? You know, it was founded in '68. ”

Sitting in the computer chair, Bossak sighed: "If you set up a business, I don't expect to make the company bigger, as long as I can popularize the technology of routers." After all, we're in an industry that's changing the world! ”

"yes, isn't that the whole of Silicon Valley? Change the world, how many founders with a net worth of billions just drive a second-hand Chevrolet to work...... Wait, not planning to make the company bigger!? ”

Seeing Alice's eyes glaring in shock, Bosak naturally shrugged his shoulders.

"yes, as long as we can spread the technology? Isn't it the highest enjoyment to sit in an office and watch your products change the world? ”
