CNGI-CERNET2, which is one of the network backbones of China Next Generation Internet project (CNGI), is undertaken by the network center of China Education and Research Network (CERNET), jointly with 25 universities, including Tsinghua University, Peking University, Shanghai Jiao Tong University, Xi'an Jiao Tong University, Southeast University, South China University of Technology, Northeastern University, Huazhong University of Science and Technology, University of Electronic Science and Technology of China, Beijing University of Posts and Telecommunications, Beihang University, Fudan University, Tongji University, University of Science and Technology of China, Zhejiang University, Xiamen University, Shandong University, Central South University, Dalian University of Technology, Chongqing University, Lanzhou University, Tianjin University, Harbin Institute of Technology, Zhengzhou University and Jilin University.

CNGI-6IX( Beijing ) is the international exchange point of the whole CNGI project. CNGI-CERNET2/6IX plays an important role for China 's next generation Internet development.

CNGI-CERNET2 backbone runs IPv6 protocol and connects 25 PoPs distributed in 20 cities in China with the speed of 2.5Gbps/10Gbps. Meanwhile, the transmission rate of Beijing-Wuhan-Guangzhou and Wuhan-Nanjing-Shanghai is 10Gbps. Each PoP provides the 1Gbps/2.5Gbps/10Gbps access capacity for the access network. CNGI-6IX, the domestic/international exchange point, located in Beijing , interconnects to the six network backbones of CNGI, including CERNET2, China Telecom, China Unicom, China Netcom/CSTNET, China Mobile and China Railcom, by 1Gbps/2.5Gbps/10Gbps respectively, and connects with American Internet2 by 155Mbps-2.5Gbps, the European GEANT2 by 1Gbps-2.5Gbps and Asia-Pacific APAN by 1Gbps.

Since the opening in 2004, CNGI-CERNET2 backbone has connected more than 200 IPv6 access networks of universities and R&D institutes in China, supported technical trials and application demonstration, and provided excellent environment for world-wide next generation Internet research.

CNGI-CERNET2/6IX has become the key fundamental infrastructure for Chinese next generation Internet technology research, key applications development, core equipments of next generation Internet industrialization.
