[Nanjing, China, June 21, 2021] At the recent 5th Future Network Development Conference, Huawei jointly released the Future Network White Paper on Deterministic Networking Technologies with industry partners, including Purple Mountain Laboratories (PML), Beijing University of Posts and Telecommunications (BUPT), 5G Deterministic Networking Alliance (5GDNA), Jiangsu Hengtong Optic-Electric Co., Ltd., and Jiangsu Future Networks Innovation Institute. The white paper details ways in which deterministic networking technologies can be leveraged to build future-oriented networks; it also introduces ways in which deterministic networks will help vertical industries to become digital, intelligent, and linked together in the information age.

Several notable guests attended the release ceremony, including Liu Yunjie, Academician of the Chinese Academy of Engineering and Director of PML; Jason Dai, President of Huawei Cloud Core Network Strategy & Business Development Department and Chairman of 5GDNA; Xuan Chuanwu, Deputy General Manager of Jiangsu Hengtong Optic-Electric Co., Ltd.; and Huang Tao, Professor of BUPT and Director of the Future Network Center of PML.

The Internet has unlocked a plethora of innovative services, including voice calling, e-commerce, and video conferencing. Having said that, the “best-effort” Internet cannot provide the deterministic ultra-low latency, ultra-low jitter, and ultra-high reliability needed for the emerging systems of the primary, secondary, and tertiary industries. These systems include smart manufacturing, unmanned transportation, ultra-remote control, intelligent decision-making, telemedicine, smart agriculture, and e-sports. Transcending the limits of conventional networks, deterministic networks can set an ultra-low maximum limit for latency, jitter, and the packet loss rate; flexibly control the ranges of uplink and downlink bandwidth; and establish an ultra-high lower limit for service reliability, guaranteeing the quality of communication for industry-specific services.

The released white paper specifies deterministic networking as the evolution target of the next-generation network and the springboard for developing China into a network, industrial, agricultural, and service powerhouse. Deterministic networking technologies can enable existing networks to be reshaped to provide real-time, high-quality, and highly reliable services, which will fuel the digital transformation of industries and deliver premier user experience.

The white paper also explains the development, standardization, application, features, and requirements of different deterministic networking technologies, including Time Sensitive Networking (TSN), Flexible Ethernet (FlexE), Deterministic Networking (DetNet), Deterministic IP (DIP), Deterministic Wi-Fi (DetWiFi), and 5G Deterministic Networking (5GDN). On top of this, the white paper offers suggestions on how these technologies can be leveraged by different industries.

Deterministic networking technologies are enabling more and more industry-specific applications, which, in turn, promote the development of technologies. Recent years have witnessed the rapid commercialization of 5G and its increasing contribution in digitizing industries. Driven by such a trend and the continuous promotion by 5GDNA, deterministic networking has been commercially used in a wide array of industries, including industrial IoT, the Internet of Energy, smart transportation, Internet of Healthcare, and multimedia. The 5GDN-enabled Smart Campus at Hengtong Optic-Electric Co., Ltd. is an example of one of the practices. During this process, 5GDNA has been devoted to consolidating the industry consensus, piloting projects, and fostering a sustainable ecosystem with industry partners. These efforts are ascending 5G and deterministic networking technologies to new heights.

The future of deterministic networking is promising, but the path to implementing it will be challenging. To implement it quickly and steadily, all industry partners should work together toward the same objectives — to converge local, wide-area, wired, and wireless deterministic networks; upgrade the quality of products and services in different industries; deliver customized products and services to both individual and industry customers; and accelerate the digitalization of industries. To achieve this, we can first adopt the public network integrated non-public network (PNI-NPN), select the best network option for each industry individually, reserve the resources for service innovation, and define an adaptive deterministic network architecture. Together, we can build future-proof networks and create an advantageous deterministic networking ecosystem.
