General Office of the CPC Central Committee, the State Council recently issued a "promote the Internet Protocol version sixth (IPv6) scale deployment plan of action" (hereinafter referred to as the plan), proposed to use 5 to 10 years, the formation of the next generation Internet technology system and industrial ecology, built the world's most large-scale commercial deployment of IPv6 network, to achieve the next generation of the Internet application in the depth of the integration of economic and social fields, and become an important leading force in the global development of next generation internet.
Plan put forward by the end of 2018, China IPv6 the number of active users will reach 200 million, among Internet users accounted for not less than 20%, the amount of users ranked the top 50 commercial websites full support for IPv6 IPv6; by the end of 2020, the number of active users of more than 500 million; by the end of 2025, the network, terminal application, full support for IPv6.
Due to the shortage of IP addresses, there are about 4000000000 devices sharing IP addresses around the world. In China, there is a widespread use of private IP address translation to deal with the problem of insufficient IPv4 addresses. Compared with IPv4, the IP address length of 128 bits in IPv6 will increase by 340 trillion IP addresses, which not only solves the urgent need of network address depletion, but also provides huge network address space for massive device connections in the era of Internet.
The volume expansion and security upgrading will make the Internet industry ecosystem face a comprehensive upgrade. This will support the rapid development of mobile Internet, Internet of things, industrial Internet, cloud computing, big data, AI and other new formats together with 5G technology.
Upgrade from "room number" to "door number"
The various stages of the planning objectives: by the end of 2018, the benign development of market driven environment basically formed, IPv6 number of active users reached 200 million Internet users in the proportion of not less than 20%; by the end of 2020, IPv6 more than 500 million active users, among Internet users accounted for more than 50%, no longer use private IPv4 address the new network address.
By the end of 2025, Chinese IPv6 network scale, user scale, flow scale will be ranked first in the world, network, terminal application, full support for IPv6, complete the smooth evolution of the next generation Internet upgrade, a global leader in the next generation Internet technology industry system.
The research department of CCID Institute of network space ministry Director Liu Quan told reporters in twenty-first Century economic report, objectives, tasks and steps in the deployment plan had made a very careful deployment, the first stage is now only about a year's time, can be predicted that the next period of time will significantly accelerate the deployment of IPv6.
He said that although the Chinese Academy of Sciences and other institutions are already deploying IPv6, most of them are in the pilot network of education network. The scale deployment is not fast enough. Most of China is currently using IPv4.
It is reported that the current network of IPv6 network has covered more than 800 colleges and universities, and already has 6 million IPv6 network users. There are more than 15 million IPv6 users in the IPv6 pilot cities of Telecom, Unicom and mobile. The number of domestic IPv6 users is about 20 million.
Lu Feng, deputy director of the Internet Research Institute of the CDI Research Institute of the Ministry of industry and information, told the twenty-first Century business reporter that IPv6 had been slower than before. The main reason is that there are corresponding alternative technologies to solve the problems faced by China.
In China, there has been a problem of using private IP address conversion to cope with the shortage of IPv4 addresses, and even to form a trap for private IP address dependence.
For example: a unit only a number, this number is the social general position code, query the number can be found in the unit position, but because the number is limited, each room unit number and their internal number, which is equivalent to the private IP address common.
"In some local area networks, there are usually some IP addresses under the IP address. These IP addresses are not searched on the Internet, nor have they been integrated into the international unified management system. Liu Quan said, "some of the internal websites are not being visited when they are being visited externally, which is worse from the perspective of efficiency, convenience and ease of use."
In the view of academician, China Academy of engineering, Tsinghua University professor Wu Jianping, Chinese IPv6 "got up early, catch a late set: 2003 Chinese started the next generation Internet, trying to seize the development opportunities brought by IPv6 technology, 2008 China was built the world's largest pure IPv6 next generation the Internet, but unfortunately, in recent years to promote the deployment of Chinese IPv6 compared with other countries in the world, gradually widening the gap.
The data show that the proportion of users in the IPv6, the United States is third, Belgium is the first two, this proportion has reached 30% to 50%, Japan has 15% users, relatively backward infrastructure in India also has 11% users, and China ranked fifty-second, only 7% of users.
Liu Quan said that before China was deploying the next generation of Internet, it had faced two routes of IPv6 and IPv9, which slowed down the process to a certain extent. And the two will send this plan to show that the country is more inclined to the IPv6 path in the strategy.
"This may be a result from the industrial system, the openness of the Internet, and the ease of use of the Internet. IPv9 uses another system. It needs to rebuild an ecosystem. IPv6 is the continuation of IPv4 ecosystem. The transition is more simple, which is conducive to smooth migration of IPv4 to IPv6.
The new opportunity for all things interconnected: "every grain of sand has a IP"
In the eyes of Liu right, compared to the IPv4 upgrade to two, the biggest advantage of IPv6 is the number of security: look from the number, the number of IPv6 address is much higher than that of IPv4, which can meet the connection of massive equipment; on the security, the security mechanism of IPv6 is more advanced, which will provide important support for networking the interconnection of all things.
The plan said that the deployment of IPv6 is the inevitable trend of the evolution of the Internet upgrade, the IPv4 global Internet problems restricting network address depletion, to guarantee the quality of service, IPv6 can provide sufficient network address and broad space for innovation, is recognized worldwide as the next generation Internet business applications.
"Vigorously developing the next generation Internet based on IPv6 will help significantly improve the carrying capacity and service level of China's Internet, better integrate into the Internet, share the achievements of global development, strongly support economic and social development, and win the initiative of future development." The report says.
In IPv4, the length of the IP address is 32 and the maximum number of addresses is 2^32; and the length of the IP address in IPv6 is 128, that is, the maximum number of addresses is 2^128.
With a sharp increase in the number of Internet users, with more and more devices connected to the Internet, IPv4 is running out of all the number of addresses, February 2011, responsible for the global IP address allocation of international Internet Organization announced its hands can be assigned IPv4 address are exhausted, but in fact, there are already about 4000000000 devices in a shared IP address.
For China, the inadequacy of the IP address is particularly prominent. This is China at a disadvantage in the international distribution of IP address resources, per capita less than half a IP address, and the address per capita exceeded 5; on the other hand, is that in recent years, with the continued advance of Internet plus ", the emerging Internet industry, business networking, smart city development rapidly. The terminal equipment of large-scale has or will have access to the Internet, IP address of unprecedentedly strong demand. Research predicts that by 2020, the number of global interconnected devices will exceed 30 billion, of which China's IP address demand may exceed 10 billion.
And deploying IPv6 can add 340 trillion IP addresses, which will be more than enough to meet the need for massive devices to enter the network. A number of respondents even pointed out that the deployment of IPv6 could allow a grain of sand in the world to have its own IP address.
Lu Feng said, the future, the deployment of IPv6 cannot take the number of active users to measure, but should be active or active terminal port number to measure, it will be for the interconnection of all things provide an important technical foundation and broad space for development.
He believes that this is a higher requirement for the security of IPv6. "Before a compound of only one number, then every household in the yard, the yard of the house would not be security threats on the street, and the relative isolation structure in the IPv6 will no longer exist, the equivalent of every household has a street number, which will face the safety the threat from the streets."
In fact, IPv6 has a higher security. In the use of IPv6 network, users can encrypt data on the network layer and check the IP packets. The encryption and authentication options in IPV6 provide packet secrecy and integrity, which greatly enhance the security of the network.
The expansion of volume and the upgrading of security make the Internet technology industry ecosystem face a comprehensive upgrading. This will profoundly affect the innovation and transformation of network information technology, industry and application.
The plan said, vigorously develop the next generation Internet based on IPv6, help to improve the network information technology capability of independent innovation and Chinese high-end industry development level, the rapid development of the emerging field of efficient support for mobile Internet, networking, industrial Internet, cloud computing, big data, artificial intelligence, creating new technologies and formats, promote the network the application of further prosperity, build advanced and open the next generation of Internet technology and industrial ecology.
