?????? 2003 By 2004, the global IPv6 address application continued to heat up, and its significant feature is that the number of address applications is constantly expanding. The reasons of IPv6 address resources, the reasons behind, and the impact generated is profound. It is only the inevitable result of the IPv6-based next-generation Internet global deployment process, and it has also deeply reflects the social competition and long-term development strategy of all regions and the country in a new round of competitions. In September 2003, Vodafone (Netherlands) applied for "/ 31", and in November, Switzerland Sunrise applied to "/ 27". In May of this year, this record is again refreshed, and the European operator TeliasONera applies to date the largest IPv6 address block allocated so far - "/ 20". According to the person in charge of the US Department of Defense, the US Department of Defense is applying for "/ 16" IPv6 address block! It is deeply based on the new round of address resource competitions, and the cause of the new round of address resource is active. Historical Flash IPv4 protocol was set in 1981 and began to deploy in 1983. Originally managed by IANA (Internet Assigned Numbers Authority) to manage IPv4 address resources allocated globally. Later IANA no longer issued IPv4 addresses directly to the Internet resource allocation area, Rir, Rir, Local Internet Registry, national Internet registration body (NIR, National Internet Registry and ISP assignment address. End users can get IP addresses from ISP. On January 10, 2004, the statistics of each RIR jointly released (see Figure 1): By the end of 2003, IANA and the number of RIR remain unallocated IPv4 addresses were 108 A-class addresses. In the 148 A-class addresses that have been assigned, 22 are allocated by each RIR, 94 directly allocated by IANA (most of which assign most of the US company, accounting for 70% of all allocated addresses), and the remaining 32 For experimentation and multicast use. By the end of 2003, China's allocated IPv4 address is 41 million, which is equivalent to less than 3 A-class addresses, accounting for nearly 2% of all assigned addresses.
IPv4 A address space status
Crisis of IPv4 era
From the distribution of IPv4 addresses, IPv4 address resources are extremely unbalanced in global distribution: US 300 million, 16.5 billion Internet users, accounting for 70% of the global allocated address (75 A-class addresses, such as MAC The college has a Class A address). China 1.3 billion population, 80 million Internet users only 41 million IPv4 addresses, which are equivalent to 3 Class A addresses. The most critical problem is: Can we expect IPv4 to change the current status of current resource distribution?
As my country's broadband Internet and the rapid development of mobile Internet, my country's Internet users will continue to grow rapidly. According to the forecast of the Ministry of Information Industry, by the end of 2007, my country's Internet users will reach 300 million, and in addition to the rapid growth of Internet users will produce a lot of demand for IP addresses, with the new generation of network-based information processes Comprehensive advancement, intelligent terminals and even mobile intelligent terminals, such as information appliances, mobile phones, PDAs, network cars, sensors, RFIDs, etc., will also have huge demand for IP address resources. The key issue is: Is there any current remaining IPv4 address to meet the huge demand for the Internet development on IP addresses?
The global IPv6 Forum announced in March 2004, the IPv4 address demand forecast for ARIN confirmed, the forecast results are: only the country with the top 15 address requirements requires additional 298 A class addresses, exceeding current IANA Three times the remaining IPv4 address library! Among them, only China needs additional 105 A class addresses! Comprehensive data analysis, the conclusions are already very clear: the remaining IPv4 addresses are far from satisfying the needs of the global and even the Internet development of the Internet in the next five years. IPv6 is our only choice.
Tomorrow's IPv6 battle
China is lagging behind other countries based on IPv4-based traditional Internet fields, which is already unbelivered. For China, in the next generation of networks, in the field of future information technology, it is a more urgent and strategic goal.
Just as the deputy dean of the Chinese Academy of Engineering said: "In the new technologies such as IPv6, China is standing on the same running line with other countries. IPv6 provides an opportunity to change the old rules and re-delineate the starting line. However, we also It must be soberly recognized that we are also facing severe challenges and tests on this new runway. "
The IPv6 protocol was developed in 1995 and began deployment in 1999. As of June 2004, 606 IPv6 address blocks have been allocated through each Rir (see Figure 2). Among them, China 11, which accounts for 1.8% of the number of IPv6 address blocks, but so far, my country's IPv6 address block allocated is default "/ 32" without a larger IPv6 address block.
Each RIR IPv6 address allocation
In fact, from 1999, each Rir began allocating IPv6 addresses. After five years of network deployment and resource allocation process, the new round of address resource competition has been initially exposed. In the new round of address resource competition, the United States still has a wind. According to the joint statistics released by each Rir (see Figure 3): By the end of 2003, the number of IPv6 address blocks allocated in the world is 499, of which the IPv6 address block allocated in the United States ranks first in the world, a total of 73 blocks The total number of addresses accounted for 15% of the world's total number, the United States, Japan, Germany, the Netherlands, and the United Kingdom accounts for nearly half of the world's total (48%).
Global IPv6 address country distribution
The above data only statistics the number of IPv6 address blocks, and ignoring the size of each address block. In fact, the current application IPv6 address block is the default application size "/ 32". If the large-scale address allocation of the world's continued increase in the world has been taken into account, the share of IPv6 address resources we allocated is even more rare.
The meaning behind the address resource
In fact, IP address resources have the meaning of the Internet and even the entire information technology, which is equivalent to the meaning of land resources, mineral resources, etc. for a country. The global pattern of resource distribution in traditional Internet has become a fact, and there is no more opportunity and development space for later people. For China, it is a more urgent and strategic goal for the initiative of the next-generation Internet resource allocation.
The information technology industry is both a national national economy's basic industry and pilot industry. At the same time, the openness and global characteristics of the Internet and even information technology itself determine the development of information technology industries inevitably based on the big background of the global information industry, while Conduct specifications must also follow the principles and norms of global unity. In terms of address resource allocation, the most basic allocation principle is: First come to pre-served and on-demand assignment. This basic criterion applies to address assignments based on IPv4-based traditional Internet fields, and also applies to address assignments based on IPv6-based new generation.
In a new round of resource reorganization and distribution, it is possible to preemptive resource allocation, which requires rapid decision-making and rapid deployment of "first" as a "demand" for long-term planning and strategic layout. Taking the United States as an example: The US Department of Defense not only currently actively applies for "/ 16" huge IPv6 address block, which is used for development needs within 2 years, and has even made planning and apply for address requirements within 10 years. The resource is fully guaranteed to achieve the implementation of its "information grid network full to IPv6 transition" strategic objectives. The address resource allocation is based on decision and deployment, and the long-term planning and strategic layout is based on the application. This is the premise of obtaining address resources. In fact, once a bad address resource is obtained, it will promote and promote the entire deployment process, and support the countries in the world's information technology, products, and commercial operations.
In addition, it is worth noting that the address resources are the same as the land resources, mineral resources, etc., is a limited resource that is not renewable within a limited time. Even if today, it seems that IPv6 can provide, and it is also exhausted. One day, we must strive for sufficient address resources as soon as possible, provide full protection for the flying development of the next generation of Internet industries in my country.
China demand and potential
The competition for the next generation of Internet address resources has just opened the battle, it is worthy of being, on this new starting line, there is no insurmountable gap. We should maximize our development services to our development services under the premise of fully understanding and grasp the rules. There are many people in my country, the development of networks, the development of networks, and business operations urgently requires large-scale address resources. At the same time, due to the natural advantages of China's own huge market potential, the development potential of the next-generation Internet based on IPv6 is unmatched by other countries. As Mr. Latif, Chairman of the World IPv6 Forum: "China is not ordered for global IPv6 development, IPv6 'killer application' will take the lead in China!" In other words, China itself is the "killer application" of global IPv6 development! " China's market size is developing IPv6's largest driving force. Developing the next generation of Internet will gain a leading advantage in the core technical field, promoting product development of domestic, driving manufacturing development, which will drive the transformation and upgrading of traditional enterprises, promote industrial informationization and national defense informationization Implementation of strategic objectives, enabling China to enter the first camp in the world information technology field, and even become a chased object.
In fact, our country will fundamentally solve the problem of IP address depletion of high-speed growth in China's communications market, and is expected to obtain core technology development opportunities in IPv6. Soon after CNGi, the five basic telecom operators in China (except China Telecom continued to use IPv6 addresses in 2002) have been applied to the IPv6 address block from the APNIC "/ 32". CNGi itself has driven my country's IPv6 address application process.
Further, with the CNGI project as an opportunity, China's IPv6 enters the substantive development stage, and the integration between various networks, the integration between different businesses will gradually launch, IPv6 market and upstream and downstream of the entire industrial chain will be driven, and pass through Large-scale network deployment and application development brings unlimited business opportunities for the development of my country's information industry.
Suggestions
The next generation of Internet features "greater, faster, safer, more timely, more convenient, more manageable and more efficient", the following generation of Internet-based information industry will become the basic industry and pilot industry of the national economy, and Drive industrial informatization and national defense informationization, ultimately realize national informationization. It is a new topic under the situation of the informationization age. It is a long-term and arduous historical goal. It is not a mature development model to learn from the national strategic height macro guidance and overall plan. It also requires close communication and echo between government and industries, and requires comprehensive innovation in the direction of ideas, mechanisms, technology, and business operations. Under the current situation, our government and industry community urgently need to in-depth development of the development status and trend of the next-generation Internet technology, from address resource application, standard development, core technology research and development, key product development and business promotion, network size deployment, penetration Rate and commercial operations, etc., propose complete and long-term development strategies and planning, and have a targeted deployment of corresponding topics, to form a technical standard with independent intellectual property, master key technologies, develop network equipment and software to implement Industrialization lays a solid foundation, promoting and accelerating the industrialization process of my country's next-generation Internet.
Taking the information manufacturing industry as an example: Information manufacturing is the top priority of my country's information industry development, which will become the key development direction of core technology and key products in the field of information technology in my country. Whether online car, sensors, information appliances, RFID, or Other intelligent information terminals, etc. In the next 5 to 10 years, there is a huge demand for next-generation Internet address resources and west to develop potential. We should seize opportunities, premature planning and large-scale applications, for my country The development of manufacturing provides adequate address resource security.
