China first introduced IPv6 in 1998, but its current development level still lags behind that of Europe and the United States. To address this gap, China has launched an IPv6 network development plan, aiming to build the world’s largest IPv6 business application network within the next 5 to 10 years. This initiative is part of a broader strategy to promote the large-scale deployment of IPv6 across the country.
IPv6 stands for Internet Protocol Version 6, a next-generation IP protocol developed by the Internet Engineering Task Force (IETF) to replace IPv4. Unlike IPv4, which uses 32-bit addresses and can support only about 4.3 billion unique IP addresses, IPv6 provides a vastly larger address space—340 trillion trillion addresses. This ensures that every device on the planet can have a unique IP address, even with the rapid growth of internet-connected devices.
The Chinese government has taken significant steps to accelerate IPv6 adoption. On November 26, the General Office of the CPC Central Committee and the State Council issued the "Action Plan for Promoting the Large-Scale Deployment of IPv6," urging all regions and departments to implement it based on their specific circumstances. The plan outlines clear goals for the next decade, including building the world's largest IPv6 business network and achieving deep integration of IPv6 in various sectors of the economy and society.
By 2018, China aimed to establish a sustainable and market-driven environment for IPv6. The number of active IPv6 users reached 200 million, making up at least 20% of the total internet population. By 2020, this number was expected to exceed 500 million, representing over 50% of internet users. IPv6 became the standard for new networks, with full support across major websites, government systems, media platforms, cloud services, and mobile and fixed networks.
By 2025, China aims to lead globally in IPv6 network scale, user base, and traffic volume. The goal is to fully transition to IPv6, ensuring that all networks, applications, and devices are compatible. This will not only strengthen China's technological independence but also position it as a global leader in next-generation internet development.
The action plan includes several key tasks: upgrading internet application services, expanding network resources, transforming infrastructure, improving service quality, accelerating application upgrades, optimizing traffic management, enhancing security, and breaking through critical technologies to build an independent industry ecosystem.
Efforts also focus on upgrading both mobile and fixed networks. With the commercial launch of VoLTE and fiber-to-the-home projects, LTE mobile networks and fixed broadband access networks supporting IPv6 are being fully deployed. Backbone network interconnection systems are being upgraded to ensure seamless IPv6 connectivity between different networks.
In emerging fields like the Industrial Internet, IoT, smart vehicles, cloud computing, big data, and AI, network security capabilities are being strengthened. Research into security technologies and mechanisms is ongoing to ensure a safe and stable IPv6 environment.
Overall, China's push for IPv6 is not just about technology—it's about building a more secure, scalable, and future-ready internet that supports the nation’s digital transformation and global leadership in the tech sector.
Cooling Film
"Cooling Film" typically refers to a type of material designed to reduce heat buildup, often used in electronic devices, buildings, or vehicles. These films can work through various mechanisms such as reflecting sunlight, dissipating heat more efficiently, or insulating against external heat sources. They can be made from different materials and are applied in various ways depending on their intended use.
For example:
- **Electronic Cooling Films:** These are often used in smartphones, laptops, and other electronic devices to help manage heat generated by internal components. They might be applied directly to the surface of a device or integrated into heat sinks.
- **Building Cooling Films:** Applied to windows or exterior surfaces, these films can reflect a portion of the sun’s heat away from the building, helping to keep interiors cooler.
- **Automotive Cooling Films:** Used in car windows or on the vehicle's body to reduce the amount of heat entering the cabin.
