Jason (Jisheng) Dai, President of Strategy & Business Development Department of Huawei Cloud Core Network, delivered a keynote speech at the 3rd Future Network Development Conference in Nanjing.
Dai pointed out that differentiated and deterministic network service capabilities are the key to the development of 5G industry applications.
Huawei is the first in the industry to propose Deterministic Networking. By leveraging key technologies such as Cloud Native, dynamic intelligent network slicing, and heterogeneous ultra-performance MEC, the deterministic networking delivers a defined range of latency, packet loss and jitter to ensure optimal user experience, promote cross-industry innovation of applications, and enable thousands of industries.
The “best-effort” service provided by traditional mobile networks can no longer keep up with the diversified requirements of vertical industry applications. These requirements include ultra-low latency, deterministic latency, mobility, reliability, and tenant security isolation.
An example is power system differential protection in the Ultra High-Reliability and Low-Latency Communication (URLLC) scenario. When a switch command is delivered, the communication between the master and slave differential protection terminals involves electrical vector contrasting and verification of transmission path parameters.
The network needs to provide a deterministic delay of 20 ms and a jitter of 600 us or less. Differentiated and well-defined network services capabilities are called deterministic capabilities. A network with these capabilities is considered deterministic. 5G deterministic networking will help transform traditional application-adaptive networks into application-defined networks and serve the needs of different industry applications.
5G deterministic networking is based on the Cloud Native architecture. Dynamic orchestration and tenant isolation of dynamic intelligent network slicing technologies provide differentiated and deterministic network service capabilities for industry applications, change the operations model and work mode of key services in vertical markets, and improve the operation efficiency and intelligent decision-making of traditional vertical industries.
In addition, the heterogeneous, ultra-performance MEC platform provides the best bit-cost algorithm, computing capability, and connectivity to provide industry applications with the most appropriate differentiated and deterministic network services, and to enable mobile networks to evolve from “best-effort” to “guaranteed” delivery.
Huawei works with industry partners in smart grids, 5G V2X, VR games, 4K/VR live broadcast, and telemedicine to verify 5G deterministic networking and templates for differentiated, deterministic network service capabilities in many vertical applications. These applications include intelligent, distributed feeder automation, autonomous driving, 4K/8K live broadcast, and remote surgery. Huawei also joins hands with partners to define the industry slice template library to accelerate the use of 5G for thousands of industries.
During the conference, Huawei and industry partners discussed development of the industry application ecosystem based on 5G deterministic networking. Bei Yue, Deputy GM of Migu Video, and Li Wei, Deputy Manager of SGCC Nanjing Power Supply Company, shared their success stories of adopting deterministic networking in 4K live broadcast and smart grids. They also discussed with SGCC, China Telecom, Jiangsu FangTian Electric Technology, Strategy Analytics, and other industry partners and organizations on the 5G electricity slice industry breakpoint and its countermeasures.
Up to now, Huawei has signed more than 40 commercial 5G contracts worldwide, and won cloud and 5G awards at the Mobile World Congress for three consecutive years. Huawei will continue to innovate with carriers and industry partners to promote 5G industry development and large-scale commercial use.
