In the context of IPv9's invention patent, there are still many skeptics. According to Shenyang Bowen, he interviewed Qian Hualin, a senior scientist at the Computer Network Information Center of the Chinese Academy of Sciences, regarding the evaluation of "China's IPv9." Qian stated that "Shanghai's 'Chinese IPv9' has no relation to the IETF standards of IPv4 and IPv6. The 'digital domain name (ENUM)' in China's IPv9 is not the same as the 'Digital Domain Name' used by the IETF, which is responsible for developing and promoting Internet standards."
The existing IPv4 protocol address space ranges from 1.0.0.0 to 239.255.255.255 (excluding 127.0.0.0 to 127.255.255.255), totaling around 4.2 billion addresses. As the Internet evolved, it became clear that this limited number of IP addresses was insufficient for future growth. In the early 1990s, discussions began on the next generation of Internet protocols, with organizations like the IETF and ISO/IEC leading the way. These efforts resulted in several influential standards.
Chinese engineers have made significant progress in IPv9 research, and today, IPv6 has become the internationally recognized next-generation standard. However, IPv9 serves as the core architecture for the future Internet.
IPv9 was designed to avoid large-scale changes to existing IP protocols, ensuring compatibility and environmental protection by reducing carbon emissions. Its main idea involves integrating the TCP/IP protocol with circuit switching. By using routers compatible with multiple protocols, the system allows for the simultaneous use of IPv4, IPv6, and IPv9 addresses. This gradual transition aims to replace the current structure without disrupting the existing network. Due to its rational design, IPv9 has attracted attention from ISO and the Internet Society.
The Friends of IPv9 Overseas Association acknowledges the value of the International Wisdom Society’s concerns, which are closely related to IPv9 technology. To address these issues, the association has gathered experts worldwide to analyze them from an IPv9 perspective and submit their findings for review. The full study is now available for public reading, and experts globally are encouraged to continue offering insights.
**I. Overview**
In the International Wisdom Society document IWS-G13051, the conflict between large address space and communication speed is highlighted. Solving this issue requires a multi-dimensional approach rather than a binary one. This article uses China's IPv9 as an example to explore the implications of large address schemes. IPv9 is well-known for its "big address" concept, which has been adopted by the Ministry of Industry and Information Technology's Decimal Network Standards Working Group. Given its maturity and detailed technical solutions, it provides a solid basis for evaluating the feasibility of large address designs.
**II. The Concept and Evolution of IPv9's Big Address**
IPv9 was initially developed by the US IETF between 1992 and 1995 as a replacement for IPv4. The working group was called TUBA, with "BA" standing for "Big Address." Thus, the big address was a central feature of IPv9.
The need for a big address arose due to the limitations of IPv4, which had a 32-bit address format, making it insufficient for growing demand. As early as the 1990s, the IAB realized the danger of address exhaustion and sought new protocols to expand the address space. IPv9 proposed a solution with a longer address format, and later, competing protocols like IPv6 also adopted similar ideas.
However, during the IETF's evaluation of next-generation protocols, the address lengths of IPv6 and IPv9 were significantly different, leading to debate. IPv6 was originally designed with 62 bits, but critics argued it wasn't long enough. IPv9 proposed 128-bit addresses, twice as long as IPv6. Despite this, IPv6 eventually won out due to political and standardization factors, although it later adopted the 128-bit address format from IPv9.
This led some to believe that IPv6 shared the big address concept with IPv9. However, there are significant technical differences between the two, and the address length alone does not equate to the same concept.
**III. Address Length and Network Transmission Burden**
From the history of the IPv9 and IPv6 competition, several observations can be made:
1. Longer address lengths provide more address space.
2. They should be forward-looking to meet long-term needs.
3. Sufficiently long addresses ensure practical value.
4. Therefore, big addresses are necessary and advantageous.
5. Longer addresses increase transmission time, creating a contradiction.
6. The key is balancing address resources and network efficiency.
7. If there's a need for a certain length, it must be adopted despite potential burden.
8. When prioritizing service demand over network burden, the former should take precedence.
**IV. China's IPv9 Big Address Concept**
China's IPv9 fully implements the big address concept. Its basic address length is 256 bits, double that of IPv6 and the original TUBA scheme. It also explores addresses longer than 256 bits, including 1024-bit applications, turning previously unrealistic ideas into real technologies.
Moreover, China has pioneered research into addresses over 1024 bits, such as 2048 bits, finding practical value. For instance, character direct routing and address encryption rely on large address spaces. China's decimal address format also includes annual ring design, enhancing management and usability.
By allowing direct use of domain names as IP addresses, China's IPv9 improves efficiency and security, especially in cloud computing environments.
**V. Overcoming Network Transmission Efficiency Issues**
Some may worry that 1024-2048-bit addresses will burden the network. However, Chinese experts have addressed this through multi-length address formats, supporting both short and long addresses. Technologies like unscheduled positioning help reduce transmission time, offsetting the impact of long addresses.
Additionally, other innovations such as character direct routing and local priority transmission protocols improve network performance, making the burden of long addresses negligible in many cases.
**VI. Conclusion**
In summary, big addresses do not necessarily increase network burden. By replacing domain names with character addresses, unnecessary steps are reduced, improving efficiency and security. Small addresses also help reduce wireless cell overhead.
China's IPv9 not only implements the big address concept but also enhances it with practical innovations. Through a new framework, it ensures high performance without excessive burden. This is a balanced approach that achieves both goals.
Currently, there is a trend of overly critical evaluations in the tech field. Some experts focus on minor flaws to dismiss new technologies, which is unwise. Comprehensive assessments and deeper analysis are needed to determine whether problems can be resolved.
With this approach, China's innovation capabilities can grow, and its network and information security can be strengthened.
