The country’s optical fibre-based CENI network is operational and achieving zero packet loss with delays of less than 20 microseconds
Industry experts likened the internet service – realised through China Environment for Network Innovations (CENI), a national research facility connecting the country’s largest cities – to a “high-speed rail for computers”.
According to Xinhua Daily, the CENI service is based on an innovative network architecture that combines the strengths of optical communication technology and deterministic networking to deliver fast, reliable and high-capacity data services.
By integrating the high-speed transmission capabilities of optical communications with the low latency and high reliability of deterministic networks, CENI enables efficient and stable data transfer, it said.
“CENI has achieved zero packet loss, with delay jitter under 20 microseconds, even under full network load, spanning 13 provinces, 13,000km (8,080 miles), and handling 10,000 deterministic services,” said Liu Yunjie, Zijin Mountain Laboratory’s chief scientist and a member of the Chinese Academy of Engineering.
According to Liu, the network service is set to support industrial internet applications and AI model training, as well as assist China’s “Eastern Data, Western Computing” strategy.
