On August 24, at the sixth future network development conference held in Nanjing, three "world's first" major scientific research achievements in the field of network communication - wide area deterministic network system, cloud native computing network operating system, and 6G TK μ The extreme connection wireless transmission test platform v1.0 was officially released. Among them, the world's first wide area deterministic network system simulates the "high-speed rail" system, proposes a transmission mechanism based on time slots, a concurrent service flow shaping mechanism, and an efficient service flow scheduling algorithm, develops a deterministic large network operating system, realizes unified time slot scheduling of the whole network, and realizes heterogeneous networking of Huawei and Xinhua three deterministic devices for the first time based on the future network test facilities, and officially opens a network covering Beijing, Nanjing The wide area deterministic network in 35 cities such as Shanghai realizes zero packet loss and delay jitter of less than 20 microseconds under 100% network load, 13000km distance through 13 provinces and cities, and 10000 deterministic services. This technology system is expected to solve the problem of traditional Internet congestion and disorder, promote the transformation of the Internet technology system from "best effort" to "ensuring needs", support the major deployment of the country such as "East digital West computing" and "carbon neutralization", and enable major digital economy application fields with high requirements for network quality, such as telemedicine, intelligent Internet connected vehicles and metauniverse. The world's first cloud native computing network operating system realizes the unified management and control of heterogeneous and multi-party computing network resources. It can provide a one-stop service of "computing power + network" for business systems, supply computing network resources in the cloud native mode, and enable users to focus on application and traffic demand without paying attention to infrastructure and IAAs (infrastructure as a service). This will fundamentally change the current business mode of separation of computing and network, and binding of resources and operations, so as to realize major application scenarios such as "East digital West computing", network cloud integration, industrial Internet and metauniverse. 6G TK released this time μ The extreme connection wireless transmission test platform v1.0 is supported by key technology breakthroughs such as sub-6ghz (1 billion Hz), millimeter wave and terahertz full spectrum unified access, cell free large-scale MIMO (multiple input multiple output) and quasi real-time intelligent resource allocation. Its wireless transmission technology capability has been greatly improved compared with 5g. The platform adopts a new architecture of integrated real-time transmission of photons and terahertz optical fibers. It has completed 200gbps on-line transmission and 1tbps off-line transmission in the 385-435ghz terahertz frequency band, respectively, creating a record of the world's highest transmission rate publicly reported in the terahertz communication field; It has completed the large-scale distributed MIMO wireless transmission test compatible with 5g commercial terminals, and has the expansion capability of large-scale distributed nodes. The core key technical indicators have reached the highest level in the world. This achievement marks that China has made important progress in the research and development of 6G candidate technologies, and has laid a solid foundation for the realization of the development goal that the future 6G wireless transmission capacity is higher than that of 5g.
