This time, the expansion and upgrading of national Internet backbone direct connection points has optimized the overall Internet layout in China, basically solved the long-distance bypass problem of Internet Interconnection in most regions of China, and formed a national Internet communication pattern of mutual support, balanced coordination and integration. On May 19, with the completion and opening of two national Internet backbone direct connection points in Jinan and Qingdao, China's network infrastructure was once again enhanced. So far, the number of national Internet backbone direct connection points in China has reached 19. Shandong Province has realized the layout of "one province with two direct connection points" for the first time, which has become an important symbol of further optimization of China's Internet architecture. Xiaoyaqing, Minister of the Ministry of industry and information technology, pointed out that as the top-level key link of China's Internet interconnection architecture, the Internet backbone direct connection point is a key hub for network interconnection and an important part of the national information infrastructure, and a key task determined in the outline of the national "14th five year plan". Optimize the efficiency and quality of inter network communication The Internet backbone direct connection point is the hub for converging and dredging regional and even national inter network communication traffic. Previously, Shandong inter network traffic needed to be diverted to other provinces, but the long-distance diversion outside the province often caused network data packet loss and long delay, poor inter network interconnection and insufficient inter network switching capacity due to excessive congestion of the diversion link. It is reported that after the backbone direct connection points in Jinan and Qingdao are completed, the data on the Internet can complete information grooming and interaction in Shandong Province. The inter provincial network delay will not exceed 30 milliseconds, the inter network packet loss rate will be controlled below 0.01%, and the inter network communication speed and quality will be greatly improved. "The straight line between two points is the shortest". The direct effect of the construction of direct connection points is to reduce the cross regional traffic diversion and improve the speed and quality of network connection. Not only are users expected to bid farewell to the network jam, but the aggregation and radiation effect it produces also provides favorable conditions and creates a good environment for stimulating the new application of new technologies and promoting the intelligent upgrading of various industries. As Weihaibo, general manager of Shandong Unicom, said, after the completion of the construction of national Internet backbone direct connection points in Jinan and Qingdao, the flow of mutual visits within the province will not go out of the province, which will help speed up the construction of digital economy infrastructure in the province. Zhounaixiang, governor of Shandong Province, said that the opening of Internet backbone direct connection points in Jinan and Qingdao will lay a more solid network foundation for the development of "new infrastructure" such as Shandong Industrial Internet and big data center, and will be an important milestone in promoting the high-quality development of Shandong's digital economy. Today, Qingdao has formed an obvious first mover advantage in the field of industrial Internet. A total of 15 projects have been approved by the industrial Internet innovation and development project of the Ministry of industry and information technology. The central government has supported nearly 400million yuan, and the number and amount of funds are among the highest in similar cities. After the official opening of the national Internet backbone direct connection point, Shandong Province has become the province with the strongest network connectivity in China. Qingdao's digital economy has ushered in an iterative development opportunity and will become a veritable "testing ground" for cutting-edge emerging technologies. Strengthen network infrastructure support As the domestic digital economy continues to heat up, the central and local governments at all levels pay more attention to the construction of information infrastructure, especially the construction of new infrastructure. The introduction of key network facilities has become an active choice for many places to promote industrial transformation and upgrading. Whether it can become one of the core exchange hubs of the national communication network and become the hub and distribution center of national data transfer is crucial to further optimize and improve the investment environment of digital economy and promote and drive the implementation of digital economy related industries. It is precisely because of its far-reaching significance that national Internet backbone direct connection points have been regarded by major cities as a must for the development of digital economy. On October 29, 2021, the Ministry of industry and information technology approved the establishment of national Internet backbone direct connection points in Jinan and Qingdao. It took only more than half a year from approval to opening. It is understood that the opening of national Internet backbone direct connection points involves major intra network and inter network adjustments at the backbone level. The network system, transmission system, business system, computer room supporting facilities and other facilities of telecom operating enterprises need to be upgraded synchronously, with a large investment. Among them, Qingdao Unicom has a total investment of more than 100million yuan, covering inter network interconnection, intra network adjustment and other contents. Qingdao Mobile has newly built three high-specification 200g platform backbone direct optical transmission network (OTN) transmission loops, laid a total of 304 km of optical cables, realized the laying of 30 km of optical cables for the bridge over the sea, and enabled two national data centers, Fushan road data center and Qingyun data center, as direct connection points. As an important national communication hub, the national Internet backbone direct connection point has opened up the "information artery" of data interconnection, is the key infrastructure to reach the "nerve endings" of users, and has become an important opportunity for the iterative development of the digital economy. China's Internet was founded in the 1990s. After years of development, China's public Internet has formed four operational backbone network interconnection units: Chinatelecom, China Mobile, China Unicom and China Radio and television. Once, Internet traffic in the central and western regions needed to "transit" to Beijing, Shanghai and Guangzhou. With the increasing demand for network infrastructure support from the development of local information construction and industrial transformation and upgrading, on December 30, 2013, the Ministry of industry and information technology added 7 National Internet backbone direct links in Chengdu, Wuhan, Xi'an, Shenyang, Nanjing, Chongqing and Zhengzhou. The reporter learned from the China Academy of information and communications that the expansion and upgrading of national Internet backbone direct connection points this time has optimized the overall Internet layout in China, basically solved the long-distance detour of Internet Interconnection in most regions of China, and formed a national Internet communication pattern of mutual support, balanced coordination and integration, which is conducive to improving the performance of China's Internet network, promoting cloud computing The data center has gathered in the central and western regions with various Internet information sources, accelerating the industrial transformation and upgrading of the central and western regions, and promoting the coordinated development of regions is of great significance. With the acceleration of the construction of the national information infrastructure system of "one network, all interconnection, ultra-high speed and strong empowerment", new national Internet backbone direct connection points are still under construction. Build a solid foundation for the development of digital economy When vigorously developing the digital economy has become an important direction to promote the quality and efficiency of China's economy in the new era, the quality of the development of the digital economy has been affected to a certain extent by the network performance and network efficiency. According to Yang Bo, deputy director of the Internet Network Research Department of the Institute of industry and planning, China Academy of information and communications, as the digital infrastructure base for all information activities, the Internet carries a large number of data storage, transmission and exchange functions of digital economic activities. It can be said that the full life cycle activities of production, trade, service and socialization involved in the digital economy depend on the high-quality construction of Internet network infrastructure Operation. Yang Bo pointed out that the scale of China's Internet network continues to grow, the network layout continues to be optimized, the network quality continues to improve, and the quality and efficiency of the Internet network as a whole are improving, but there are still insufficient and unbalanced development problems. For example, some provinces, especially the western provinces, still have some detours in the inter network interconnection, and the inter network interconnection architecture needs to be further optimized and improved. When the project of "counting from the east to the west" injects inexhaustible momentum into the strength, optimization and expansion of China's digital economy and high-quality economic and social development, the urgency of upgrading the Internet network infrastructure becomes more prominent. Yanliang, general manager of Inspur cloud Information Technology Co., Ltd., said that to transfer the "data" from the eastern region with tight energy resources to the western region with abundant energy resources, the first thing we need is a basic network that "keeps pace with the pace". Whether the data is transmitted to the western region for computing or to the western region for storage, it is a great challenge to the data transmission capacity. The improvement of Internet network quality and efficiency involves the comprehensive optimization and upgrading of network end-to-end multiple levels and key links. The industry agrees that the new digital infrastructure represented by Internet backbone direct connection points provides important support for promoting high-quality economic and social development. Appropriately adding new national Internet backbone direct connection points during the "fourteenth five year plan" period and continuously promoting the optimization and adjustment of Internet Interconnection and interconnection architecture are the key to effectively solving the bottleneck of digital economy development.
