China's IPv6 Network Officially Up And Running
China's IPv6 Network Officially Up And Running

The China Education and Research Network Information Center (CERNIC) reported that it has implemented the world's first - and largest - Internet based on the new IPv6 (Internet protocol version 6). Known as CERNET2 (China Education and Research Network 2), it links up 25 universities in 20 cities across China. Networks configured with the new IPv6 protocol can transfer data at speeds up to 10GB per second.

China has high hopes for this technology, that it reportedly will spend $168 million to develop, half that amount going to CERNET2. Xinhuanet, the country's state news agency, said, "By creating a digital network in their own homes, in the near future Chinese people can use it to enjoy video and audio communications, informational resources, and the benefits of far-away education and health care services."

One immediate benefit to China from IPv6, is the addition of a far greater number of IP addresses than what is now offered by IPv4. IP addresses number around 4 billion, with the US controlling 74 percent of these, Xihuanet reports. This has created an imbalance in the distribution of IP addresses, which the new network will help to correct.

Other Asian companies and governments, including Japan and South Korea, have been working to roll out IPv6-based networks to resolve this imbalance and avoid a shortage of addresses.

While 10GB per second is an accepted figure for data transfer speeds over IPv6 Internets, speeds four times that amount are being reported. A news report said that a CERNET2 trial, in which data was passed from Beijing to Tianjin on December 7, clocked in at a peak speed of 40GB per second. Chinese officials say this is the fastest transfer speed ever achieved anywhere, with real applications.

"This next-generation Internet protocol can transmit data at 10 gigabits per second."
I guess the author of this article isn't familliar with networking concepts. IP has nothing to do with speed, it's a communications protocol, not a physical layer protocol. I could run IPv6 over a dial-up modem, would that automatically make it 10Gbps? No. It'd still run at whatever the connection speed is.

One big benefit of the IPv6 is to solve the problem of the shortage of IP addresses so I'm all in favor of this. At last!
