This morning (November 13), a press conference for the opening of the world's first 1.2T ultra-high-speed next-generation Internet backbone channel connecting Beijing-Wuhan-Guangzhou was held at Tsinghua University. This ultra-high-speed next-generation Internet backbone channel is based on my country's independently developed next-generation Internet core router 1.2T ultra-high-speed IPv6 interface, 3X400G ultra-high-speed multi-optical path aggregation and other key core technologies. It has a total length of more than 3,000 kilometers and realizes the integration of system software and hardware equipment. All domestically produced and independently controllable.

According to reports, the 1.2T channel can complete the transmission of 150 high-definition movies in 1 second, and the transmission efficiency is more than 10 times that of the current 100G network. With the explosion of AI large models, computing power has become a new productive force in the digital economy era. This channel has built the key infrastructure in the computing power era, achieving large bandwidth, low latency, and high-reliability quality connections, and providing computing power networks with Important Guarantee.

At present, the global Internet 400G backbone channel technology has just begun to enter business, and it is generally predicted that "Terabit" ultra-high-speed backbone channel technology will appear around 2025. The opening of the world's first 1.2T ultra-high-speed next-generation Internet backbone channel is an important milestone in the development of global Internet infrastructure.

The 1.2T ultra-high-speed next-generation Internet backbone channel is not only a major technical test result of Tsinghua University's "National Major Science and Technology Infrastructure Future Network Test Facility: Future Internet Test Facility FITI" project, but also an important component of FITI's high-performance backbone network. At present, the channel is running smoothly and reliably, passing various experimental tests and reaching the design indicators.

Wu Jianping, leader of the FITI project, academician of the Chinese Academy of Engineering, and professor of Tsinghua University, said that the completion and opening of the 1.2T ultra-high-speed next-generation Internet backbone channel has provided important technical reserves for my country's construction of ultra-high-speed next-generation Internet, and will surely become China's contribution to the global next-generation Internet. important contribution to the development of the Internet.
