If the United States shuts down 13 global root servers, not only our domestic Internet can not function normally, the United States Internet can not function normally.
The so-called root server is the most important strategic infrastructure of the Internet, is the hub and core of the Internet, it is used to manage the Internet home directory. All IPV4 root servers are managed by ICANN, an Internet Domain Name and Number Assignment Agency authorized by the US government. It is responsible for the management of the global Internet Domain Name Root Server, Domain Name System and IP Address. There are only 13 root domain name servers in the world. 10 of them are in the US, 2 in Europe, 1 in Asia and 1 in Asia.
If 13 global root servers are shut down, then the global Internet is at a standstill. OK, everyone is not playing.
On June 23, 2015, the Snowman Project, a pilot project for testing and operating the root server of the Global Next Generation Internet (IPv6) based on the new technology architecture, was officially launched. On November 28, 2017, the "Snowman Project" has completed 25 IPV6 (Internet Protocol Version 6) root servers worldwide, and China has deployed four of them, breaking the predicament that China did not have a root server in the past. By this time, 13 new roots and 25 IPv6 roots have been formed. In this case, if the United States shuts down the original 13 root servers, then most of China's networks will not be available, only a small portion of the resources that have been transferred to IPv6 can continue to be accessed.
In fact, the focus of this problem is that China is still subject to the status quo of people in many core technologies, which is determined by historical factors, for a considerable period of time, there is still no way to change. Like ZTE, Americans send a "supreme ruler" to monitor ZTE's development.
But from a further time perspective, China's technological progress is still very fast, especially since the reform and opening up, especially in the last decade, China has made a lot of investment in technology research and development.
For example, in 2016, China's R&D investment intensity reached 2.11%, 0.05 percentage points higher than the previous year, more than 2% for three consecutive years. This is still far from the OECD average of 2.40%, but it has exceeded the EU average of 2.08%.
In 2017, the total R&D expenditure in China was 1750 billion yuan, an increase of 11.6% over the previous year, and an increase of 1 percentage point over the previous year. The intensity of R&D expenditure (R&D expenditure to GDP ratio) was 2.12%, which was 0.01 percentage point higher than the previous year.
In February 2018, the British magazine Nature published Why Scientific Researchers Want to Go to China, saying that China will surpass the United States as the world's largest R&D investor by 2019.
In other words, China's economy is shifting from a demographic dividend to an engineer dividend, and technology drive will bring the most profound changes to China. According to McKinsey Co analysis, by 2025, the contribution rate of innovation to China's GDP will be as high as 50%.
Strive hard, young partners, if you want to get rid of the core technology by others, it needs every Chinese to work hard to contribute to the country's scientific and technological progress.
