Application Cases of Industrial Routers in SD-WAN: Unlocking Efficient Network Connectivity for the Industrial Internet of Things

In the realm of the Industrial Internet of Things (IIoT), the stability, flexibility, and efficiency of network connectivity are pivotal for enterprises to achieve intelligent transformation. With the emergence of Software-Defined Wide Area Network (SD-WAN) technology, the application of industrial routers within SD-WAN architectures has become increasingly widespread, offering enterprises more intelligent, reliable, and flexible network solutions. This article shares several typical application cases of industrial routers in SD-WAN to help you gain a deeper understanding of the practical value of this technology.

1. Case One: Global Network Reconstruction of a Multinational Industrial Group

1.1 Background and Challenges

A multinational industrial group, with its global headquarters in Shanghai, operates in 53 countries and regions worldwide. Faced with the high operational and maintenance costs of traditional MPLS private lines and the instability of public internet transmission, the enterprise urgently needed a more efficient and flexible network solution to support its global operations.

1.2 Solution

The enterprise introduced SD-WAN technology and deployed industrial routers as key network nodes globally. At domestic sites, hardware smart gateways were deployed, enabling dual-line hot standby to ensure high network availability. For overseas branches, virtualized terminal access methods were adopted, reducing deployment costs and maintenance complexity.

Through SD-WAN's intelligent traffic scheduling hub, the enterprise achieved millisecond-level switching of cross-border transmission paths. As the hub for data transmission, industrial routers can intelligently select the optimal transmission path based on real-time network conditions and application requirements, ensuring the stable operation of critical business.

1.3 Implementation Effects

• Cost Reduction: After replacing 70% of the original MPLS private lines, the enterprise's annual network expenditure decreased by 58%.

• Efficiency Improvement: The synchronization delay of the PLM system at the Sino-German production base was reduced from 420ms to 110ms, shortening the new product development cycle by 22%.

• Reliability Enhancement: The smoothness of the global video inspection system's footage improved threefold, and the efficiency of equipment fault response increased by 40%.

2. Case Two: Remote Monitoring and Maintenance of a Smart Factory

2.1 Background and Challenges

A smart factory, equipped with multiple production workshops and a large number of industrial devices, needed to implement remote monitoring and maintenance to improve production efficiency. However, traditional network architectures struggled to meet the demands for real-time data transmission and remote control, and there were security risks.

• Security Enhancement: The integrated security functions effectively prevented network attacks and data leakage risks, safeguarding the enterprise's core data security.

3. Case Three: Cross-Regional Data Sharing of an Energy Enterprise

3.1 Background and Challenges

An energy enterprise, with multiple production bases and data centers nationwide, needed to achieve cross-regional data sharing and business collaboration. However, traditional network architectures struggled to meet the demands for real-time transmission of large volumes of data and suffered from issues such as network latency and bandwidth bottlenecks.

3.2 Solution

The enterprise introduced SD-WAN technology and deployed industrial routers at each production base and data center. Industrial routers support multiple network connection methods, such as the internet, 4G/5G, etc., enabling link load balancing and failover.

Through SD-WAN's intelligent path selection function, the enterprise could select the optimal data transmission path based on real-time network conditions and application requirements. As the bridge for data transmission, industrial routers ensured fast and stable data transmission. Meanwhile, the enterprise also utilized SD-WAN's centralized management and control platform to achieve unified configuration and monitoring of various network nodes.

3.3 Implementation Effects

• Data Sharing Efficiency Improvement: Cross-regional data sharing became more efficient and convenient, enabling the enterprise to obtain real-time data information from various production bases and data centers.

• Business Collaboration Capability Enhancement: Through data sharing and business collaboration, the enterprise could better coordinate production plans at various production bases, improving overall operational efficiency.

• Network Performance Optimization: SD-WAN's intelligent path selection and link load balancing functions optimized network performance, reducing issues such as network latency and bandwidth bottlenecks.
