Netherlands local time July 28, at the 78th Annual Internet Engineering Organization IETF conference, Tsinghua University Computer Science and technology department Professor Wu won the Internet's highest award-Jonathan Postar Award.

The Jonathan Postar Award, which was created in 1998 by the Internet Association, is the highest award in the Internet world. Wu This award, is the first time Chinese scientists won the award.

As one of the main pioneers of the domestic Internet, Wu almost participated in the whole process of building the Internet from scratch in China. As early as the late 70, when the vast majority of Chinese people did not even hear the computer, Wu has begun to carry out the relevant research on internet technology.

According to Wu recalls, at that time China faced the international technical blockade, the research is difficult. However, it is in this difficult environment, he has presided over more than 20 national large-scale research projects and projects.

It is recognized that the most outstanding contribution in Wu's many projects is that he created "China Educational and Scientific Research Network (CERNET) demonstration Project" in 1994, and promoted it to become one of the backbone of China's internet, and CERNET has been used in more than 1800 universities and units in China.

Since 1998, Wu is also committed to the next generation of Internet technology, that is, IPv6 research, become China's IPV6 technology, the most important catalyst. IPV6 is the acronym for the Sixth Generation Internet Protocol, which is the next generation IP protocol designed by the IETF to replace the current version of the IP Protocol (IPV4).

In the current IPV4 framework, the world's IP address is only 6%, compared with the rapid development of the Internet, about 4.5 billion of the world's IP address will be nearly exhausted this year. With IPV6 technology, the number of IP addresses around the world will increase from the existing 2 32 to 2 of the 128 times, the number of which can be described: if the Earth's surface paved with a layer of sand, then each grain of sand can have a separate IP address.

Promoting IPv6 is of special significance to China. Under the IPV4 framework, the global IP address is distributed by international organizations, the United States with 300 million people with 1.5 billion IP addresses, 5 IP addresses per capita, and as the world's fastest-growing internet, as of last year, the average Chinese Internet users only 0.6 IP addresses.

Under the impetus of Wu, China has built IPV6 backbone network, and has made breakthrough achievements in some key technologies, such as real source address authentication, IPV6 transition technology and so on.
