"Although we are in the same running line with other countries in the R & D and deployment of IPv6, China is undoubtedly faced by severe challenges, even the next generation of Internet CGNI projects. Sun Jianfei, the business directors of the Understand Tiandi Interconnection Information Technology Co., Ltd., revealed that the reporter was discounted to this report.
From the end of 2003 to 2004, the first is Wadin (Netherlands) to apply / 31 (Note: "/ 31" for IP address resources, equivalent to 2128-31, 297 IPv6 addresses, below That); September 12, APNIC (responsible for IP address allocation agencies in the Asia-Pacific region) assigned to NTT (West) / 30 IPv6 address block; Swiss Sunrise applied to / 27 in November.
In May of this year, this record is again refreshed, and the European operator TeliasONERA applies to the RIPE NCC to date the maximum IPv6 address block allocated so far - / 20. So far, China's IPv6 address block applied by each RIR is default allocation value / 32.
The United States will first come first
Since the RIR (Internet Resource Allocation Area Domain NOTICE Regional Internet Registry) Assign IP addresses Following the basic principles of "First-to-Pioneering and on-demand Assign" Expanded, the record was repeatedly refreshed.
The direct cause of this series of phenomena in just a few months is that IPv6 substantive or even large-scale deployments in various regions of the world have produced demand for IPv6 addresses and even largest. The default size assigned by the IPv6 address is / 32, but the current greater address block has been allocated by the RIR to issue a demand - this is the next-generation Internet global deployment process based on IPv6. Inevitable results.
Despite the limitations of 70% of the United States, 70% of the IPv4 era, it is limited to its existing interests, leading to negative wait-and-see attitude towards IPv6, and has once behind the rest of the world, but recently the United States is active. A new round of IP address resource competition.
On July 6 this year, the US Department of Defense Ministry of Defense Information System (Disab) announced in the IPv6 peak forum held in South Korea, the US Department of Defense is currently using the IPv6 address block of / 16, and the United States plans to apply within the next ten years. A larger IPv6 address block to fully meet the modern war demand of its high-level information confrontation in the network.
It is reported that the US Department of Defense is issued in June 2003, the article "IPv6" is issued in June 2003, the equipment supplier who does not support IPv6 will be excluded from the purchase list of the Ministry of Defense. By the 2008 financial year, the entire network of the US Department of Defense must complete the transition to IPv6 and make an IT budget of more than $ 30 billion. Subsequently, the US Department of Commerce also acts.
In October 2003, the US Department of Commerce established a special working group to investigate IPv6. The survey includes: IPv6 domestic and foreign development status, deploying IPv6 cost and benefits, international interconnection, safety issues, US competitiveness and government in IPv6 The role of development should be ... this means that the US government has begun to act, and the US government has begun to act and is carrying out a long-term deployment of careful and orderly.
China starts slow
In fact, the IPv6 address assigned by each RIR in 1999, the world has been deployed and resource allocation processes in five years of IPv6 network deployment. According to the joint statistics issued by each Rir this year: By January 2004, the number of IPv6 address blocks allocated in the world is 499, the US allocated IPv6 address block number is the world, totaling 73 pieces, accounting for the world The total number of addresses allocated in the total number of the United States, Japan, Germany, the Netherlands, the United Kingdom account for nearly half of the total number of global, about 48%, China only 11, accounting for 1.8%. As of June 2004, in the world's 606 IPv6 address blocks, China still only 11 pieces - and this data only statistics the number of IPv6 address blocks, ignoring the size of each address block. The IPv6 address block allocated in my country is the default / 32, which is far from the US Department of Defense / 16 huge address blocks. If the large-scale address allocation of the world's continued increase in the world has taken into account, China's share of IPv6 address resources in China is even more rare.
According to the prediction of the Ministry of Information Industry, by the end of 2007, my country's Internet users will reach 300 million. In addition to the rapid growth of Internet users will produce a lot of demand for IP addresses, with the comprehensive information process based on new generation networks Advance, smart terminals of various networking, even mobile intelligent terminals, such as information appliances, mobile phones, PDAs, network cars, sensors, webcams, and RFID tags, will also produce huge number of uncomfortable demand for IP address resources.
According to the regulations, the IP address can be applied by various national telecom operators and ISP. By the end of 2003, my country's five basic telecom operators (except China Telecom continued to use the IPv6 address of 2002), and the IPv6 address block is applied from the APNIC.
A innumerator revealed that "China Telecom's development is earlier, and there are many IP addresses for the application. Currently, there is currently no crisis, but China Mobile and China Unicom, nearly two years with mobile Internet high-speed Development, now faces a certain degree of IP address lack of threats. "
The current solution of telecom operators is through the network address translator (NAT). This NAT mode is essentially destroyed the nature characteristics of the Internet or information communication: two-way communication between end-to-end. For some real-time communications, such as IP phones, video conferencing, although the "middleware" measures of various repair remedies can also be implemented in the NAT environment, they can also achieve the instability and complexity of the network. Sex, also improved the cost of operators or business deployment, management and maintenance.
Guo Ruo, the Vice Chairman of the International IPv6 Forum, founded by Guo Ruibo, founded by the Beijing Branch of Beijing Cocquet, "To the end of next year, China can build the world's largest CNGi network. However, there is also an application problem - if there is no commercial Network, RIR does not approve the application for IP address blocks. IPv6 address assignment needs to be based on network size, such as how many nodes are available on the network, and how much end users can bring IP address resources, not freely allocation. "
Some of the 3G industry is slow, the most active in the promotion of IPv6 is the upper and lower ends of the industrial chain - equipment manufacturers and receiving terminal equipment, such as router vendors and mobile phone manufacturers. Operators in the middle of the value chain are active. The reason is that China's IPv4 deployment is still using space.
"IPv4-based investment is now only 5% of return. Of course, the operator is not willing to push IPv6 now!" A senior R & D engineer in the Nokia Mobile Manufacturers' Research Center pointed out that "all factors, operators can't see a ready-made The application business that must be based on IPv6 network is the key, that is, the lack of killer products is the largest bottleneck in IPv6 industry! "- This is the upstream supplier, mobile phone manufacturers are enthusiastic about IPv6, but they can't afford to operate their interests. The reason, therefore affected China's planning and resource accumulation on the next generation of Internet IP addresses. Transfer from: Economic Observer
