China has successfully built its next generation Internet with Internet Protocol Version 6 (IPv6), replacing Internet Protocol Version 4(IPv4), to become the world leader in this field.
China's next generation Internet, or CNGI, has proposed a new search system structure and developed a special method for the transition between the two Internet generations. It has present seven draft standards to the International Internet Organization.
In developing the CNGI, China built the world's first IPv6-only network and for the first time used domestic IPv6 routers, the core Internet components in the national network.
The CNGI-CERNET2/6IX passed an examination by an expert team organized by the Ministry of Education at Tsinghua University over the weekend. Experts say the network is world standard and its three innovations will give China more clout in this field.
China launched the CNGI project in 2003 and in 2005 completed its first next generation internet, the CNGI-CERNET2.
The success of the CNGI's core network has freed China from dependence on foreign key internet technologies and products and ensured national information security.
Proposed in the mid-1990s, it is estimated that the next generation Internet will transmit information 1000 times faster, at a speed of 40 gigabytes per second.
With this new technology, many things are possible. A doctor may be able to clearly see a live broadcast of tumor surgery on a liver in another country. The IPv6 is much less vulnerable to security breaches, but if there is a problem, it is easier to expel the virus or hacker and resume services. An IPv6 source address validation system has been created to ensure network safety.
The new generation Internet has more safety features, is easier to manage and has an almost inexhaustible supply of Internet addresses.
Experts say this development is of strategic significance as China will no longer need to rely on foreign technology for Internet construction.
With transmitting speeds ranging from 2.5 to 10 gigabytes per second, the CNGI's backbone network connects core nodes in 20 cities across the country.
In 2002, 57 research fellows wrote to the State council proposing they build the next generation Internet backbone network. In August 2003, the project was launched. By the end of 2004, the CERNET2 was built to connect with 25 core nodes across 20 major cities so that Chinese universities and research units could be connected by high speed internet as well as with other countries' next generation internet.
It's believed that in the IPv4 era, China's technology was 8 to 10 years behind other countries. IPv6 will reach an international standard and even be ahead of the standard of some nations.
What is the next generation of the Internet?
There isn't a unified definition of what the next generation of Internet is as it is a gradual process of change. However, the major consensus includes the following:
Larger: With IPv6 protocol there will be a huge space for addresses, greater variety and a higher quantity of information allowing for the wider application of the Internet.
Faster: Over 100 gigabytes per second
Safer: It can identify Internet addresses, as well as the identity and rights of visitors.
More timely: With good quality control, people can watch live broadcasts easily.
More convenient: Wireless telecommunication application
More manageable: Orderly management, effective operation and maintenance.
More effective: There will be social and economic benefits from this model.
