The exchange lecture lasted for three hours, and although the content of Zhou Shuo's lecture became more in-depth the further he went, the students present listened to it with relish.

Unlike the students who just listened with relish, the lecturers, professors, and some experts who happened to arrive with nothing happened to be frowning the more they listened.

Without him, the level of these things that Zhou Shuo talked about is too high.

Is this his own level, or is it the result of the collective research of the Pan Han Group? If it's at its own level, it's terrible. But even the collective achievements of the Pan Han Research Institute may show that the Chinese have come to the forefront of the world in network technology.

This news is not good news for the network, which is already showing more and more power. Many of you are even eating this line of food, so would it be nice to have a strong competitor popping up?

The bell rang again, and Zhou Shuo's lecture came to an end. The students happily talked about what they had heard in the lecture and walked out of the classroom.

However, many of you who looked a little older did not rush out of the classroom.

"Hello Mr. Zhou, can I take the liberty of taking a little time for you?"

Zhou Shuo stopped packing his hand, raised his head, and said with a dumb smile: "It turned out to be Professor Allen, of course it's no problem, do you have something?" ”

"That's it-" Alan hesitated for a moment, and nodded reluctantly: "We have a few old friends who want to have an in-depth exchange with Mr. Zhou, I wonder if you have time tonight?" ”

"Okay." Zhou Shuo didn't expect it to be so smooth, rolled up his sleeves and looked at the time, and said with a smile: "It's better to find a restaurant nearby." Professor Allen can invite a few more peers, and I'll pay for it. ”

"That's embarrassing. Mr. Zhou is a guest, and there is no reason for guests to spend money......"

Alan waved his hand repeatedly. I feel a little embarrassed in my dark heart. The so-called exchange he mentioned was actually just that the Dutch colleagues wanted to explore Zhou Shuo's bottom line and see how in-depth the research level of the Pan Han Group was. To put it bluntly, it was to talk to Zhou Shuo, not to really want to have any academic exchanges.

"That's it, it's five o'clock in the afternoon, and I think it's half past six. Locations and guests, and have to trouble Teacher Allen. ”

Zhou Shuo couldn't help but say, and settled the matter like this.

After the lecture. Zhou Shuo first went back to the hotel to change his clothes, and then received a call from Allen. The two agreed on the time and place, and everything was ready, only the east wind was owed.

While there was still some time, Zhou Shuo even made an international call to China and asked someone to investigate Allen's background in detail. Just after six o'clock, he flagged down a taxi and rushed to the address that Allen had said.

"This is Mr. Zhou Shuo from China, the discoverer of graphene. This is Professor Bob of Network Engineering at Leiden University, where he focuses on cybersecurity. ”

Alan pulled Zhou Shuo. One by one, they introduced him to the identities of the guests who went to the banquet today.

It's a European-style dining room with long tables lined with crisp white tablecloths filled with silver candlesticks, bone china cutlery and gold-encrusted knives and forks, and guests are seated on either side. Talking to each other close to each other.

When Zhou Shuo arrived, everyone's eyes fell on him. Even if the reputation of the Chinese was not obvious in 1997, no one would ignore a billionaire.

Of course. There may be people who don't care about power and money, but they certainly won't appear at today's dinner.

There were about twenty people sitting on either side of the five or six metre long table. Everyone looks dressed formally. There are many people who are very familiar with Zhou Shuo, and they should have met at the exchange symposium in the afternoon.

One by one, I got to know the guests who came to the banquet today. It should be said that Alan is still very concerned about this matter. Although they are all his colleagues at Leiden University, at least there is not much parallel goods mixed in. These people are basically experts in communications, software and chip design, and manufacturing, and the scope of Zhou Shuo's lecture in the afternoon coincides very much.

As Zhou Shuo sat down, soon the restaurant began to serve. Western food is different from Chinese food in that it is not served all at once, but one is eaten in order before the second dish is served. Therefore, everyone can eat more neatly, and there will be no messy feeling of cups and plates. Of course, this is indeed a boon for patients with selection difficulties.

"Mr. Zhou, I heard Allen say that you have formed a Pan Han Group in China, and you have a deep research in network equipment? Can you tell us a little bit about what you've achieved? ”

Zhou Shuo put down the knife and fork, wiped the corners of his mouth with a napkin, and nodded with a smile: "No problem, we have two most important projects in the network equipment of our Fanhan Group. One is the R&D project of a single-chip 100G router, and the other is the R&D project of a wireless LAN. ”

Looking at the different expressions of everyone at the table, Zhou Shuo smiled secretly in his heart. He is very aware of the level of research in Europe in this area, not to mention the single-chip 100G router in 1997, even if it is a single-router 100G solution, they can't come up with it now. It's already very good that their backbone network can have 10G routing equipment.

“100G？ Is what Mr. Zhou said true? The speaker was Professor Jim Haaker, who majored in IC design at Leiden University, and he sat at the front, probably a professor with a very high status in the university.

"As far as I know, at present, even Cisco has not achieved 100G single-chip technology, and Panhan Group can achieve it on a single chip? But it's not a 10×10G solution, right? ”

Zhou Shuo smiled, shook his head and said: "Of course it is not a 10×10G solution, we are a 100G single-chip technology realized through guòOTN technology." While construction costs have risen, the unit cost of communication has dropped significantly. ”

“OTN？ This is the wavelength division multiplexing technology of optical fibers, but as far as I know, this technology is still in a state of research......"

All the relevant industry scholars present put down the knives and forks in their hands and carefully pricked up their ears to listen to Zhou Shuo's words.

"The difficulty of WDM technology is in the split multiplexer and the dewavelength multiplexer, which are applied to both ends of the fiber optic line. We started to study this technology in 1995, and at present, it has only completed the simplest dual-channel wavelength division multiplexing, and the transmission bandwidth has barely reached 100G, which is still far from the theoretical 25T bandwidth. ”

Don't look at the modesty that Zhou Shuo said, but just a little bit of tone in his mouth has already surprised the professors present. OTN technology was still in the incubation stage in 1997, and unless you are a professional, you probably have never heard of it. The International Telecommunication Union (ITU) only began to develop the OTN series of standards in 1998, and the main standards were basically perfected by 2003.

This is thanks to the consistent tracking of international advanced technology by Huaxing Group, where Zhou Shuo worked in his previous life, and this OTN technology is also a project that he has followed from beginning to end. The level of technology in 2015 cannot be replicated, but it is not a problem to implement an early technology model.

For example, the early prototype of this technology may not be technically demanding, but more importantly, it is actually a way to solve the problem. Like this kind of thinking, how much does Zhou Shuo want in his head? Just a few words of advice can already save the relevant personnel how many detours. It takes two or three years to come up with a basic application product, which is already a relatively slow progress.

Zhou Shuo saw that everyone did not dwell on the topic of OTN anymore, so he turned to another technology: "We have developed a Solar chip based on SPARC architecture, and the Solar processor uses MIP macro technology, 0.25 micron process, and 400MHz frequency. With this chip, two upstream and downstream processing units are designed separately, each of which can handle 100G of digital quantities. ”

"I heard you right! 400MHz CPU, oh my! This is the world's first CPU with a clock speed of 400MHz, right? Jim Hack shook his head, looked at Zhou Shuo with a sigh and said: "Even if it is optical communication, uplink and downlink branch processing unit, 400MHz main frequency, can achieve 100G transmission capacity, this is also incredible!" ”

Zhou Shuo gently sipped the wine in the glass, shook his head and said: "Intel also has a CPU under development, which should be the PentiumII processor that will be launched next year, and it will also use a 0.25 micron process to reach a 400MHz frequency. We are only one step ahead of Intel to use our own advanced lithography machine, and this advantage may not be maintained for long. ”

He looked at the professors on the table whose faces had improved a little, and said with a smile: "The advantage of this Solar chip is not its process technology, but the MIP macro technology designed by our Fanhan Shi yàn room, which can greatly reduce the amount of computing of the processor and increase the number of processing per unit of time. It can be said that this Solar chip is a CPU that is extremely optimized for network transmission. ”

Speaking of which, Zhou Shuo's status in the later Huaxing Group is not low, and many projects have been followed. But his main focus is still on chip design and manufacturing. Among Huaxing's network equipment products, this Solar processor can be regarded as a classic, and he can design it even with his eyes closed. Later, the reason why Huaxing Group was able to bring Cisco to the sky and the earth is that the Solar-based solution can be said to have contributed a lot!

Just the two techniques that Zhou Shuo casually revealed made the professors present a little frightened. Originally, they just wanted to touch the bottom of the Chinese in this field, but they found that the other party was like the Mariana Trench, and there was no bottom at all.

There is already a Cisco in this world, if another Panhan Group emerges, then what are the European companies in the market of communication equipment?

They don't know that there was no such thing as European companies in the original history. (To be continued......)
