The first national major scientific and technological infrastructure -
Future Network Test Facility
Adoption of national acceptance
Officially put into operation
This marks China's Internet "national weapon."
Born in Nanjing.
"Compared to the traditional Internet
The most striking feature of the facility is the end-to-end certainty."
Academician of the Chinese Academy of Engineering, General Director of the Future Network Pilot Facility Project
Liu Yunjie introduced
Entering the 21st century, the traditional Internet gradually exposed many problems, and countries all over the world have laid out basic research in the field of future network. 2010, Liu Yunjie and other experts suggested to the state to lay out the "Future Network Pilot Facility Project". 2015, the facility landed on the construction of Nanjing. December 3, the Acceptance Committee appraisal, project The Acceptance Committee recognized that the project has fully completed the construction objectives and agreed that the project has passed the national acceptance. The project has produced a series of important technological breakthroughs and accelerated the process of key technology research, transformation and application of achievements and industry cultivation and development in the field of information and communication in China.
Building a strong network, General Secretary Xi Jinping has always been mindful of this, and has twice been briefed in Nanjing on the construction of the future network.
"The general secretary's entrustment has given us great impetus." Liu Yunjie said that the facility passed the national acceptance, marking China's entry into the world's advanced ranks in the field of network, with a more advanced, more efficient, high-speed network infrastructure, which can be used for thousands of industries to embrace AI to provide better quality and more cost-effective services.
Currently, the facility hasCoverage of 40 cities nationwide
Interconnection with existing networks at home and abroad
Supports 4096 parallel trials
Adoption of facilities
Network data can be efficiently and at high speed
with low latency and low jitter
Packet loss rate (probability of data loss)
Only one in a million.
Taking "China Tianye", which is also a large scientific device, as an example, "China Tianye" generates hundreds of terabytes of data on a daily basis. Tests show that 72TB of data through the traditional Internet (10 megabit dedicated line) transmission takes 699 days, using the future network test facility 100G deterministic network only 1.6 hours.
The facility can also be connected to the arithmetic centers around the formation of arithmetic network to support the large model of cross-domain training, 2000 km cross-domain pooling arithmetic efficiency ratio up to a single data center 98%, which can significantly reduce the time and arithmetic costs, cracking the high-end arithmetic in China, "less, miscellaneous, scattered" problem.
Reporters at the test site to see, facilities support, Qingyang, Wuhan, Hangzhou, 3 places linked to the large model training, single iteration training time stabilized at about 16 seconds; after the closure of the return to the traditional network, the time immediately rose to 33 seconds.
Both universities, institutes and enterprises can carry out Internet research and validation through the open test facilities. During the trial run, the project has successfully supported 120 innovation experiments involving major national strategies, cutting-edge technology innovation, and emerging industry applications.
Academician of the Chinese Academy of Engineering, the future network test facility national acceptance committee co-director Wu Hequan said that the current arithmetic application is still in its infancy, the future may emerge all kinds of unknown challenges. Expect through the future network test facilities, for researchers to build a fault-tolerant, support innovation and exploration platform, accelerate the transformation of technical achievements, help the real economy high-quality development.
