Huawei today announced that it has worked with research partners to complete a deterministic WAN innovation trial, achieving the world's first 100-microsecond delay jitter control over a transmission distance of more than 2,000 kilometers.
According to Huawei, this has laid an important foundation for production control and high-precision services such as ultra-long-range industrial interconnections and high-precision vehicle networking.
Currently, the number of global machine communication connections has approached 30 billion, and is growing rapidly year by year, and is expected to reach 10,000 billion connections in 2035.
According to Huawei, the communication mode and traffic model of intelligent machines will change fundamentally, in which remote control, intelligent manufacturing and other data communication scenarios put forward high deterministic bearing requirements of ultra-low latency and ultra-low jitter on the network.
Relying on the China Environment for Network Innovations (CENI) and the Yangtze River Delta Integrated Test Environment, Huawei built a large-scale test environment covering 13 core nodes in Beijing, Nanjing, Shanghai, Zhengzhou, Wuhan and Hefei.
This is basis to achieving more than 2,000 km transmission distance, less than 100 microseconds of delay jitter control, verifying the deterministic IP forwarding technology in the WAN environment, Huawei said.
Liu Yunjie, director of Zijinshan Laboratory and academician of the Chinese Academy of Engineering, pointed out that the new deterministic network technology can achieve high-precision control of network bandwidth, path, delay and jitter to meet the microsecond delay jitter protection needs of future industrial automation, industrial remote operation, holographic communication, vehicle road collaboration and other services.
Huawei's deterministic IP forwarding technology has been fully verified in the large-scale test environment, demonstrating better high-precision deterministic forwarding performance," said Kevin Hu, president of Huawei's data communications product line.
