China launched the world’s first ultra-high-speed next-generation Internet backbone with a bandwidth of 1,200 G bits per second (1.2T), according to a press conference held on November 13 at the Tsinghua University in Beijing.

The backbone network, jointly developed by Tsinghua University, China Mobile, HUAWEI and Corporation, has a total transmission network spanning more than 3,000 kilometers and linking the cities of Beijing, Wuhan and Guangzhou.

The FITI backbone network is a major technological achievement of the national Future Internet Technology Infrastructure (FITI) project. Since its operational test on July 31 of this year, it has operated stably and reliably, successfully passing various tests.

Its operation is possible on the basis of key Chinese national-owned technologies, such as the 1.2T ultra-high-speed IPv6 interface of the next-generation Internet core router and multi-path aggregation of this type of speed. Both the software and hardware are manufactured in the country.

The FITI, built by 40 Chinese universities, including Tsinghua, is based on IPv6 technology. The central nodes of its high-performance backbone network are distributed in 40 universities in 35 cities across the country.

In April 2021, FITI’s high-performance backbone network went into operation, achieving interconnection with IPv4/IPv6 test facilities both in China and abroad.
