The longest distance in the world! China Mobile builds 'Ultra High Voltage' with 'digital data in the east and counting in the west', 5,000 kilometers from Harbin to Guiyang with 70Gbps transmission

According to news on June 22, recently, China Mobile has overcome the industry's high-throughput transmission problems in the "Long-FAT Network" (Long-FAT Network, which refers to a network with long transmission distance and large bandwidth) in response to the demand for wide-area high-throughput transmission of massive data. , completed the pilot verification of the world's longest ultra-long distance of 5,000 kilometers and 70Gbps ultra-high throughput data express wide-area high-throughput technology from Harbin, Heilongjiang to Guiyang, Guizhou. This pilot test verified that China Mobile faced the IT inter-cloud data backup scenario, based on China Mobile's two major cloud data centers in Harbin and Guiyang and cloud private network for data transmission, verifying many leading innovations in data express wide-area high throughput technology ability. First, super long distance. The network transmission distance between China Mobile (Harbin) Data Center and China Mobile (Guiyang) Data Center exceeds 5,000 kilometers, passing through switches, gateways, routers, firewalls, OTN and other types of network equipment. The distance is long, the equipment is heterogeneous, and the network traffic complex. The second is ultra-high throughput. At a transmission distance of 5,000 kilometers, the effective throughput of traditional wide area transmission protocols is only about 14% of the 100G physical bandwidth. Wide-area high-throughput technology relies on innovations such as new wide-area congestion control algorithms and multi-stream concurrent transmission mechanisms to achieve effective throughput of 100G physical bandwidth exceeding 70Gbps. 1TB IT cloud disaster recovery data is transmitted in less than 2 minutes, which is 5 times higher than the effective throughput of traditional protocols. times. The third is plug and play. The wide-area high-throughput system is "plug and play" and only needs to be deployed on the terminal side. It is compatible with mainstream server platforms and requires zero modification of network equipment and no network upgrade costs. According to public information, China Mobile has been conducting research on wide-area high throughput technology for data express since 2020, and has made many breakthroughs in innovative mechanisms such as reliable transmission protocols, wide-area congestion control algorithms, and rapid packet loss recovery. In October 2023, China Mobile was the first in the industry to achieve stable large-scale data transmission over a 2,200-kilometer long distance from Guizhou to Beijing; in April 2024, it established a computing and network integrated pilot platform team and carried out pilot verification of wide-area high-throughput technology. China Mobile revealed that this year it will complete product trial runs for mission-oriented, high-throughput, safe and efficient product-level capability packaging, as well as data migration backup, big data collaborative computing and other scenarios, laying the foundation for the next step of opening up related product capabilities to the outside world. This pilot verification of data express wide-area high-throughput technology marks that my country's "East-to-East Digital and West-to-West" strategy also has key technologies such as "West-to-East Power Transmission" and "UHV" to support national strategies such as "Network Power" and "Digital China" implementation. China's "Eastern Computing and Western Computing" project was fully launched in February 2022, and it was agreed to start the construction of national computing power in 8 places including Beijing-Tianjin-Hebei, Yangtze River Delta, Guangdong-Hong Kong-Macao Greater Bay Area, Chengdu-Chongqing, Inner Mongolia, Guizhou, Gansu, and Ningxia hub nodes and planned 10 national data center clusters.
