Huawei proposes ‘deterministic networking’ for 5G

News

Huawei claims to be the first in the communications industry to propose ‘deterministic networking’.

Deterministic networking would leverage technologies such as cloud native, dynamic intelligent network slicing and heterogeneous ultra-performance mobile edge computing (MEC).

According to the Chinese vendor, “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.”

Jason (Jisheng) Dai, President of Strategy & Business Development Department of Huawei Cloud Core Network, made the comments in a keynote speech at the 3rd Future Network Development Conference in Nanjing.

Capabilities

Dai told attendees that differentiated and deterministic network service capabilities are key to the development of 5G industry applications. He said 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.

He gave the example of power system differential protection in an Ultra High-Reliability and Low-Latency Communication (URLLC) scenario.

Dai explained: “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 milliseconds 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,” he said.

Verticals

5G deterministic networking is based on cloud-native architecture. Dynamic orchestration and tenant isolation of dynamic intelligent network slicing technologies could change the operational models of key services in vertical markets, Huawei says.

The company has signed over 40 commercial 5G contracts worldwide but is currently at the centre of a row with the US over accusations of spying for the Chinese state. Huawei strongly denies the allegations.

Last week the US put Huawei on a list of companies that American companies cannot trade with without a specific licence.
