4. What are the considerations for the key tasks deployed in the “Implementation Plan”? Answer: On the basis of consolidating and expanding the development results of the “14th Five-Year Plan” IPv6, the “Implementation Plan” deployed 10 key tasks around the new requirements for high-quality IPv6 development in the “15th Five-Year Plan”. The main considerations are: 1 is to deepen upgrading and transformation. Focus on the difficulties and blockages of end-to-end penetration, strengthen collaborative transformation of networks, applications, and terminals, increase the optimization of IPv6 networks, deepen the IPv6 volume and drainage of Internet applications, promote the use of IPv6 on all types of terminals, and further enhance the scale and traffic level of IPv6 users. The second is to expand the space for innovation. Continue to improve the “IPv6+” innovation system, strengthen research on key technologies such as intelligent wide area networks, new metropolitan area networks, and computing power networks based on “IPv6+”, strengthen the promotion and application of innovative technologies and transformation of achievements, continuously demonstrate the potential and advantages of IPv6 technology, and promote the integration and innovation of IPv6 and artificial intelligence. Improve the IPv6 standard system and enhance the international influence of technological innovation achievements. The third is to strengthen integrated applications. Promote the integration and development of IPv6 with new applications and new business formats such as smart applications and ultra-high-definition video. Driven by the digital transformation needs of the industry, we will deepen the integrated application of IPv6 in the fields of e-government, digitization of education, smart finance, smart medical care, etc., to enable the collaborative development of intelligent manufacturing, digital transportation, smart water conservancy, intelligent connected vehicles, digital villages, smart parks, etc., and enhance the quality and efficiency of the digital transformation of the economy and society. Fourth, highlight the evolution of single stack. Carry out key technical research such as IPv6 single-stack networking architectures, and select key regions and characteristic fields to carry out IPv6 single-stack pilot applications. Research and formulate implementation guidelines for IPv6 single-stack evolution, establish an IPv6 single-stack capability evaluation system, and promote the IPv6 single-stack transformation of Internet applications. The fifth is to highlight management systems. Promote simultaneous IPv6 deployment through enhanced portal management. Improve the IPv6 management system for government informatization, and clarify IPv6 support capacity requirements in system regulations such as government informatization construction. Improve app store listing standards and encourage new apps to support IPv6. The sixth is to build a strong safety barrier. Comprehensively promote the simultaneous planning, design and implementation of IPv6 deployment applications and network security protection measures. Strengthen IPv6 security technology research, improve the IPv6 protection capabilities of security products, and improve the IPv6 security protection system.
