The dream of telcos for two decades has been to completely control the network, an “Intelligent Network.” Huawei is introducing a new term, deterministic networking, with powerful backing: China Mobile, China Telecom, China Unicom, and the Ministry MIIT.
The 5G Deterministic Network Alliance is also supported by State Grid, the world’s 5th largest company with over a billion electricity customers, Wuhan’s huge Yangtze Optical Fibre and Cable, and 40 other companies.
Huawei also promoted in London the concept of “Cloud Native, One Core, Real-time Operation, and Edge Computing” (CORE.) China is about to build Edge Networks to over a billion people. It makes sense to integrate Edge and CORE from the beginning.
Cisco was the great proponent of intelligent networks, promising that the QOS and network control of Cisco routers would produce 10’s of billions in revenue for the carriers. Carriers are still chasing dreams of added revenue, which has been essentially flat for the last five years.
It didn’t happen then, but perhaps in 5G the technology is ready.
Intelligent networks require far more equipment than simple ones; I did a rough calculation that a carrier would have to buy about 3 times as much Cisco gear.
The number of engineers required goes up with the complexity of networks. Huawei has been eloquent about the need for effective automation for new networks and has interesting demonstrations of AI network management.
In many cases, it proves much cheaper to fight congestion by adding more capacity rather than more intelligence. The price of the gear comes down every year; the salaries of good engineers do not fall.
Xavier Niel proved that can work in the early days of Free in France. He served 4 million customers with two big switches and fiber to all his sites, If congestion developed, he inexpensively upgraded the hardware.
He showed me his network monitor for the previous week. There was only one point of congestion, where Telecom Italia hadn’t upgraded its side of the connection.
The stupid network isn’t always the right choice, but it certainly needs consideration.
P.S. The other problem with intelligent networks, network slicing, and QoS is that in the past they haven’t worked very well. See the work of Columbia Professor Henning Schulzrinne. In particular, QoS deteriorates where networks connect.
Huawei Unveils Industry First Deterministic Networking Oriented 5G Core Network
[London, UK, February 21, 2020] Huawei launched a press conference in London to showcase its latest products and solutions. The industry’s first deterministic networking oriented 5G core network solution made its debut at the conference. Pivoting on the key concept of “Cloud Native, One Core, Real-time Operation, and Edge Computing”, the solution provides differentiated connectivity and SLA assurance, to empower all industries.

The accelerated commercial launch of 5G around the world will deliver a superior service experience to individuals, families, and enterprises. It will also unleash the potential of industry digitization and create new opportunities for operator growth. Digital transformation requires 5G networks to serve as differentiated networks with orchestratable capabilities, dedicated networks with guaranteed data privacy, and self-service (DIY) networks with automated management. This means the 5G networks must have deterministic networking capabilities.
Huawei proposed the innovative 5G Deterministic Networking (5GDN) concept. 5GDN leverages 5G network resources to build manageable, verifiable and deterministic virtual private mobile networks, offering customers a predictable and differentiated service experience.
Huawei is the first to release the deterministic networking oriented 5G core network solution. Huawei also proposed to plan and build 5GDN around the idea of “Cloud Native, One Core, Real-time Operation, and Edge Computing.” 5GDN runs on the cloud native platform and supports microservice-based 2G/3G/4G/5G full convergence. Leveraging super-performance heterogeneous MEC, multi-dimensional dynamic intelligent slicing, and core network automation engine, it can provide differentiated network capabilities and deterministic networking experience.
- Cloud Native: The next-generation telco cloud hardware platform E9000H is equipped with in-house Kunpeng chips and runs on a switching-free architecture. With integrated IP+IT capabilities, it ensures optimal cost per bit. Leveraging the cloud native architecture, the Telco Converged Cloud (TCC) unifies the telco cloud infrastructure and supports both VM and container engines to address different requirements of central and edge networks.
- One Core: The microservice-based 5G core network is fully integrated with 2G, 3G, 4G networks and inherits all existing services. Its centralized control plane and one-stop user plane deployment improves system performance, simplifies deployment, and ensures smooth software evolution, and migration to 5G without changing cards or numbers.
- Real-time Operation: The core network automation engine integrates multiple NE functions and takes advantage of programmable workflow, data native, and AI capabilities to ensure intelligent, simplified, and agile operation of the 5G core network. Multi-dimensional dynamic intelligent slicing with minute-level automatic deployment provides differentiated virtual private networks for industries.
- Edge Computing: Super-performance, heterogeneous MEC ensures deterministic low latency and builds a new edge ecosystem based on enhanced connectivity and computing, cloud-edge collaboration, plug and play, and fast integration of third-party services.
“5G deterministic networking is the key to industry digital transformation. Huawei will work with industry partners to promote industry consensus, accelerate industry development, promote service innovation, build an industry ecosystem, and drive new 5G business opportunities”, said Ma Liang, Vice President of Huawei Cloud Core Network Marketing Dept.
Up to now, Huawei had secured over 90 worldwide commercial 5G contracts. Huawei had undertaken a series of cross-industry collaboration based on 5G deterministic networking in fields such as smart port, smart grid, smart manufacturing, AR/VR, connected vehicle, and telemedicine, greatly promoting the success of the 5G ecosystem. Huawei will continue to progress to better serve customers and promote rapid development of 5G.
