China has officially commissioned a groundbreaking national network infrastructure that demonstrates unprecedented data transmission capabilities, marking a significant advancement in global information technology. The China Environment for Network Innovation (CENI), the country’s first national science and technology infrastructure in the ICT sector, recently passed national acceptance in Nanjing and is now operational.
This revolutionary network testbed achieved what previously seemed impossible: transferring 72 terabytes of data generated by China’s Five-hundred-meter Aperture Spherical radio Telescope (FAST) from Guizhou province to Huazhong University of Science and Technology in Hubei province in merely 1.6 hours. Traditional internet methods would have required approximately 699 days to accomplish the same data transfer.
According to Liu Yunjie, academician of the Chinese Academy of Engineering, CENI represents China’s entry into the world’s advanced echelon in network technology innovation. “CENI’s passage of national acceptance enables China to deliver higher-quality services for all industries to embrace AI,” Liu stated.
The infrastructure boasts large-scale, programmable, virtualized, and open-sharing features, providing a simple, efficient, and low-cost test environment for researching innovative architectures of future networks. The development team has pioneered a service-customized network architecture internationally and created the world’s first distributed large-network operating system.
After over a decade of construction, CENI now spans 40 cities nationwide with a total optical transmission length exceeding 55,000 kilometers. The network can support 128 heterogeneous networks and 4,096 parallel heterogeneous service tests while seamlessly interconnecting with existing internet infrastructure and global test facilities.
The project has generated substantial intellectual property, including 206 international and domestic standards, 221 authorized invention patents, and 139 software copyrights. Multiple achievements have received national-level scientific and technological awards.
Wu Hequan, another academician of the Chinese Academy of Engineering, emphasized that CENI will support the development of 5G-Advanced and 6G technologies while allowing research institutions and enterprises to test various new technologies.
Notably, CENI offers dramatic improvements for AI development. Liu explained that “training a large model with 100-billion-level parameters across domains requires over 500,000 rounds of iterative development. With CENI, each training round takes only about 16 seconds,” resulting in significant time and economic savings.
Looking forward, CENI will provide open testbed support to key industries including manufacturing, energy and power, education, healthcare, and the low-altitude economy, thereby accelerating China’s digital transformation initiatives.
