C114 News May 25 (Beishan). On May 22, the 3rd Future Network Development Conference was held in Jiangning Future Network Town, Nanjing. Nanjing, as an important hub of Chinese culture in the Six Dynasties, witnessed the vicissitudes and vicissitudes of ancient and modern times.

And the city is the greatest invention of mankind. In the evolution of thousands of years, people have slowly built roads, power grids, metros These urban infrastructures are the blood of maintaining a city's operation. And the city, there is an unprecedented rich resource, that is "data resources".

Although many Internet practitioners are increasing traffic economy today, Alibaba CTO Wang Jian believes that only by relying on "data + computing + infrastructure" to make the city cohesive as a whole and become a brain can the Internet realize its real value and bring more possibilities to society.

Fragmented cities have no networks

"Today, so many experts are here, I have always felt that the understanding of the Internet and the Internet is not fixed." Wang Jian said at the Forum on the Global Development Strategy of the Future Network that the earliest Internet and the Web were almost equivalent, and then the mobile Internet came into being at the time of Web 2.0. After the combination of industry and Internet has produced industrial internet, the former Internet is also called consumer internet. "Often I'm in this industry, and I'm confused about where the Internet is?"

It was the city (brain) that made him clearly feel the need for the carrier of the network for the first time. Wang Jian further explained that if in the earliest era of the web internet, the single device was the PC terminal, the carrier of the mobile Internet era would be the smartphone. But in today's world-wide era, there is no carrier similar to PC and smartphone, so we can not really focus on it. And the city may be a whole that the Internet will connect in the future.

But the current network architecture makes the city unable to integrate, fragmentation is not our time, but the whole network space. Speaking about what the future network is, Wang Jian said, "The future Internet will treat the city as a single node", rather than a container of content and services on demand, so that data can flow smoothly, computing power can be shared, and all the data of a city can be condensed, so that the data really has the value of changing society.

There will be no more chaotic terms like mobile internet, industrial Internet and consumer internet. "There will be only one Internet in the future."

Hand over cities to data and make data change the world

How many cars are there on the road in a city at this moment? How many cars are there on the road when the road is blocked? This answer was unimaginable all over the world in the past, but today it can be answered by consuming the power of cities.

"In Hangzhou, we went to calculate for the first time, you can guess, I put this figure out, like Hangzhou, which has more than 2.8 million motor vehicles. Every day, about 1.3 million to 1.8 million vehicles pass through the road by traditional statistical methods. In fact, when there is no traffic jam, there are only 200,000 vehicles on the road." When traffic jams occur, the city brain calculates, "In fact, there are only 90,000 more cars, that is, 300,000 more cars."
