Three departments issued a document proposing to further promote the scale deployment and application of IPv6. 3

The Central Network Information Office, the National Development and Reform Commission, and the Ministry of Industry and Information Technology recently jointly issued the Work Arrangement for Further Promoting the Scale Deployment and Application of IPv6 in 222, which requires highlighting innovation and empowerment, stimulating the vitality of the main body, opening up key links, consolidating the industrial foundation, enhancing endogenous motivation, improving security, and solidly promoting the scale deployment and application of IPv6.

ten key tasks, such as strengthening network carrying capacity, improving terminal support capacity, optimizing the performance of application facilities, and expanding industry integration applications, have been deployed in the work arrangement.

according to the work arrangement, by the end of 222, the number of IPv6 active users will reach 7 million, the number of Internet of Things IPv6 connections will reach 18 million, the fixed network IPv6 traffic will account for 13%, and the mobile network IPv6 traffic will account for 45%. The IPv6 support rate of government portals at or above the county level reached 85%, and the IPv6 support rate of major domestic commercial websites and mobile Internet applications reached 85%. IPv6 network security protection capability has been greatly improved.

Looking back at the development of IPv6 technology in China, China has entered the first year of IPv6 technology development since the launch of the China Next Generation Internet Demonstration Project (CNGI Project) in 23. Supported and driven by national policies, after more than 2 years of development, the scale of domestic IPv6 users has increased rapidly, the network infrastructure construction has been basically improved, and the IPv6 network "expressway" has been fully built and entered the "opening to traffic" stage.

1. Assign an IP address to each grain of sand

as the basis of the IP protocol, and the IP address can be described as the only identification for network devices to access the Internet or local network. According to the evolution of IP protocol, IPv4 protocol was born in the early 198s, which can provide 4.3 billion communication addresses. IPv6 was officially launched by IETF in 1998, 17 years later than IPv4. However, compared with IPv4, IPv6 has a comprehensive promotion and improvement in address resources and transmission characteristics.

evolution of IP protocol

specifically, the number of IPv6 addresses has greatly increased to 2 128, which is 2 96 times that of IPv4. Even if an IP address is assigned to every grain of sand on the earth, the problem of IPv4 address shortage has been fundamentally solved. Secondly, IPv6 protocol optimizes the datagram header, deletes unnecessary fields, and the datagram header can be flexibly expanded, which greatly improves the data processing efficiency.

at the same time, IPv6 protocol also supports automatic address configuration, IPSec authentication and encryption, and defines security objectives (confidentiality, authentication and integrity) and mobility characteristics, so that hosts can be automatically addressed and devices can be plugged and played, which reduces maintenance workload with higher network manageability and effectively improves data transmission security and mobile communication processing efficiency. Continuing the advantages of IPv6 technology, the industry is constantly promoting technology-driven protocol innovation and industrial ecological improvement.

On the basis of IPv6, IPv6+ has achieved a comprehensive and systematic upgrade, with improved network programmability and network maintainability, further optimized SLA and further reduced network delay.

on the whole, as the technical foundation of the next generation internet, IPv6 and IPv6+ have broken through the bottleneck of IPv4 in terms of address space and performance security, and strongly promoted the evolution of network technology and ecological construction. Continued expansion of the scale deployment of IPv6 and its derivative technologies will be of great significance to the development of emerging fields such as mobile Internet, cloud computing and Internet of Things.

according to Xi Guohua, chairman of the China Communications Standards Association, IPv6 is the main direction of Internet evolution and upgrading, a new starting point for the innovation and development of the next generation Internet, and an important part of the construction of a network power and a digital China. The importance of IPv6 technology innovation and converged application can be seen.

2. what is the development level of IPv6 in China?

driven by national policies, the development of IPv6 in China has achieved remarkable results. Wu Hequan, an academician of China Academy of Engineering, pointed out that at this stage, China's IPv6 address resources rank first in the world, and the number of IPv6 active users and traffic have increased substantially. By the end of 221, China has applied for IPv6 address resources totaling over 6,, and the number of active users has reached 68 million, accounting for 6.11% of China netizens.

in terms of traffic, mobile network IPv6 traffic accounts for 35.15%, fixed network IPv6 traffic accounts for 9.38%, home wireless router IPv6 support rate reaches 16%, government portal IPv6 support rate reaches 81.8%, and major commercial websites and mobile Internet applications IPv6 support rate reaches 8.7%.

From 23 to 217, the development speed of domestic IPv6 and the number of broadband access users both failed to meet expectations, and once fell into a bottleneck period of stagnation. Wu Hequan said at the China Internet Conference in 218 that by the end of 217, the number of IPv6 users in China was only .3% of the national Internet users, and the number of users was only over 2 million.

As early as 212, in the Opinions on the 12th Five-Year Development and Construction of the Next Generation Internet jointly issued by the National Development and Reform Commission and other seven departments, the future development goal of IPv6 was defined, that is, the number of IPv6 users exceeded 25 million during the 12th Five-Year Plan period. From this point of view, the development of domestic IPv6 is slow, even in 217, it still can't reach one tenth of the development goal.

in November 217, after the official release of the Action Plan for Promoting the Scale Deployment of Internet Protocol Version 6 (IPv6), the development of IPv6 technology in China has improved. Since 218, the Ministry of Industry and Information Technology has organized a special campaign for IPv6 scale deployment for three consecutive years to promote the rapid increase of domestic IPv6 scale.

in order to accelerate the development of IPv6 in China, the Ministry of Industry and Information Technology and the Central Network Information Office issued the Three-year Special Action Plan for Improving IPv6 Traffic (221-223) in 221, aiming at improving the overall IPv6 traffic. In the next three years, all walks of life will be fully guided to deepen cooperation, fill shortcomings, accelerate technological evolution, and continue to promote the high-quality scale quantity of IPv6.

The relevant person in charge of the Information and Communication Development Department of the Ministry of Industry and Information Technology said in the policy interpretation that the implementation of this plan means that China's IPv6 development has entered the stage of "traffic improvement" from "network readiness" and "end-to-end connectivity", and it also shows that China's IPv6 network "expressway" has
