BYD: Building a new type of smart factory, leading the new era of "smart manufacturing" with "quality connection"

Rapid business development tests BYD's network infrastructure
In the context of manufacturing upgrading, BYD's automotive and electronics businesses are developing rapidly, which also poses a huge challenge to BYD Group's entire park network infrastructure. The specific items are as follows:

Firstly, the diversification of applications and the large-scale production and research and development of cloud based businesses have raised higher requirements for the user experience of network usage. For example, the interruption of access to research and development simulation services, as well as issues such as lag and disconnection in high-definition video conferencing, not only greatly affect the progress of core research and development services, but also impact communication experience and office efficiency. In this situation, how to ensure the high-quality carrying capacity of various businesses?

Secondly, the flexibility of BYD's various production lines increasingly relies on the wireless network, and wireless access to various terminals on the production lines has become a common demand. In the case of massive terminal access, the signal and roaming coverage ability of wireless APs, the number of accessible terminals, anti-interference ability, and network reliability in high-density scenarios will become huge challenges.

Again, with more and more wireless network terminals accessing the network, the number of wireless terminals far exceeds the number of wired terminals. Currently, the number of BYD wireless terminals on the network exceeds 100000. How to ensure that a massive number of terminals can access the network within and across the park with consistent permissions? The problem of inflexible deployment of traditional wired terminals based on access IP address permission control is becoming increasingly apparent.

Finally, the automated operation and maintenance capabilities of the network urgently need to be put on the agenda. With the increasing scale of the network and the proliferation of network devices, there are more and more network requests or problems. Therefore, BYD urgently needs to shift from the previous "passive" operation and maintenance mode relying on human labor to an automated and intelligent "active" operation and maintenance mode.

BYD collaborates with Huawei to build a high-quality 10 gigabit campus network, laying a solid foundation for intelligent manufacturing:

• Fast access: The road must be wide enough to increase production

Wired 10G to terminal: To meet the requirements of wired terminals with different speeds, the access switch can support gigabit and 10G high-speed access as needed, support business sharding, and divide different "lanes" for different businesses.

Converge high-density 10GE and core 100GE: To improve access bandwidth, it is necessary to aggregate and core support high-density 10GE and 40/100GE interfaces in order to support larger network bandwidth and more terminal access.

By using ultra wide and high-speed wired support to meet the increasing demand for high bandwidth, low latency, and other business needs, BYD has greatly improved its office and production efficiency.

Ultimate Experience: Fully wireless office and production, speed and flexibility can be achieved at the same time

In the office setting, the high-quality all wireless office network adopts a 10 gigabit uplink high throughput and high concurrency AP, supported by leading smart antennas, 3D network specifications, big data optimization and AI technology, to achieve network coverage for all employees in the group. Users can roam freely in any location without interruption of business, zero video lag, and enjoy a consistent business experience.

In the production scenario, BYD utilized Huawei's advanced 3D network planning tool for engineering survey and selected Huawei's new generation AP, which is more stable, faster, and has higher concurrency. It supports IoT integration and can connect more than 500 vehicles in production, thousands of intelligent terminal devices and sensors. It also uses big data technology and regression algorithms to actively warn hundreds of devices, further improving the network reliability of wireless transmission of production data.

In addition to supporting the ultimate experience at the network layer and application layer, Huawei's high-quality campus network also supports seamless terminal access and the ultimate experience of accompanying user business. The Huawei iMaster NCE Campus system provides centralized authentication and network authorization for user terminals accessing the office network across the entire group. Currently, it supports a user base of 300000 (supporting future evolution and expansion); Business accompanying implementation of network refinement control based on user roles and terminal types ensures that external users cannot access internal resources. Access terminals grant different access permissions as needed, enabling employees to quickly access the network. Intelligent perception of access terminal identity, location, terminal type, and other information enables refined control and provides customized network services.

The accompanying business ensures consistent wired/wireless access strategies for users at any location. Support flexible group policies, flexibly customize groups through dynamic user groups, static resource groups, and application (domain name), and implement inter group access policies as needed; Through IP Group synchronization, the core switch uniformly executes business accompanying policies, achieving unified wired/wireless policies across the entire network.

High capacity data center network creates a high-speed highway for business traffic
As a leader in the industry, with ultra wide and high-speed office and production networks in the park, it is natural to build a high-capacity data center network. In BYD's data center network, Huawei's current high-end CloudEngine 16800 series switches and CloudEngine 6800 series switches are used, creating a highway for business traffic between hundreds of thousands of terminals across the network and 2000+servers in the data center. The powerful scalability can also support future high-speed business development.

The wave of "smart manufacturing" in the automotive industry is accelerating, and BYD, as a leader in the new energy vehicle industry, is standing at the forefront of technological innovation. The successful commercialization of BYD's high-quality 10 gigabit park network and high-capacity data center network has set a benchmark for the sustainable development of new energy vehicles and the transformation of car companies, providing significant reference for intelligent IP networks to lead the new era of "smart manufacturing".
