Scarce for IPv6 applications, including Duan Xiaodong, including some of the experts, can be cut into from the Internet of things, things networking applications for separate network to carry out IPv6.
The development of Internet of Things has been attached great importance to the national level, the next few years, Internet of things will be a large-scale popularization of high-tech networking application materials market will reach 1 trillion yuan on the scale, over intelligent transportation, environmental protection, public safety, industrial monitoring, logistics, medical and other fields.
Address the development of Internet of Things made a huge demand. Telecommunications Research Institute Ministry of Industry and Internet center Baohong communications standards, said the next five years, demand for our IP 34.5 billion, of which 1.0 billion for the mobile Internet, Internet of things is expected to demand 100 million to 500 million fixed internet, and in accordance with the IP address used to estimate the utilization rate of 33%, China's future demand for IP 34.5 billion. At present, only the remaining IPv4 address is clearly no longer supports the development of networking applications.
On the other hand, with the triple play to accelerate work on IPv6 also made a strong demand. "One operator carried out three-screen business, you need to televisions, computers and mobile phones, Internet terminals, requires a lot of IP addresses, and radio and television building hoping to triple play NGB, enter the broadband market, but radio and television are more scarce IPv4 addresses allowed to launch broadband services on a tight budget at. "a device for those who wish to" communications industry newspaper "(Network), told reporters.
China Academy of Engineering Vice President, CNGI Expert Committee Academician Wu Hequan director also pointed out that Internet TV has accounted for sales of flat-panel TV sales 15% to 20%, and 50% annual growth. Triple Play makes the TV as a network terminal, a fixed rather than dynamic IP address allocation method as a major address assignment method, which requires IPv6 support. Similarly, the development of mobile Internet can not do without the same support for IPv6.
However, for China's IPv6 address should also be careful not to repeat mistakes Ipv4 times. Although the commercial deployment of IPv6 in China in the lead of other countries, but also the world's Internet users than any other country, the demand for IPv6 addresses and more strongly, however, apply to the IPv6 address is lagging far behind other countries.
According to APNIC (Asia Pacific Network Information Centre), the latest data show that China currently assigned to the IPv6 address is only 63, ranked 18th place in the world, far behind Brazil, 65000, United States, 1.5 10000, Germany and Japan more than 9800 pieces of more than 8300 pieces.
Insiders pointed out that China should establish IPv4 to IPv6 transition mechanism for the effective organization, systems and measures, a clear timetable for attention from the national level for IPv6 addresses.
Operators in action
It's understanding, encouraged by the Government, our country has overcome the three major operators currently using some of the key IPv6 technology, the choice of transition strategy With a clear direction, Wangluozhunbei basically completed.
China Telecom has deployed the first to start the next generation Internet, the experimental work of a variety of comprehensive and fully demonstrate the evolution of technology, end to end business opening, operation and maintenance and security, and explore new business models, to seek the best evolution path to next-generation Internet. At present, China Telecom has started in Changsha, Hunan, Jiangsu, Wuxi, Chengdu and Guangzhou cities in four commercial IPv6 test, and the second half of the pilot extended to Hangzhou, and Jinan.
China Mobile in 2009, completed the bearer network for IPv6 equipment, laboratory scale testing up to 912 stand-alone test, network test up to 396; and domain for the mobile group conducted a number of IPv6 testing. Duan Xiaodong noted that in 2010, China Mobile will be LTE, IMS, and the terminal as an entry point, use PNAT in IP bearer network, mobile networks and IMS networks expand current network pilot.
Nevertheless, the time is still urgent, because the pace of development of the Internet does not allow operators to conduct business in accordance with the usual rhythm of the layout, top-down option is to force speed.
