When enterprises use traditional networks to access overseas resources, they often encounter high latency, data transmission stuttering, and even service interruptions due to issues like long physical distances, network congestion, and insufficient link redundancy. So, how can these problems be solved? Enterprises can try the SD-WAN dedicated line solution.

How Does SD-WAN Dedicated Line Accelerate Overseas Network Access?

Dynamic Routing Optimization

SD-WAN dedicated lines monitor the status of global backbone links in real time, including metrics like latency, packet loss rate, and jitter. Upon detecting issues, they can switch traffic to the optimal path within 0.5 seconds. For example, traffic from China to Europe can bypass congested transatlantic public networks via a private backbone, reducing latency to within 150 milliseconds—60% lower than traditional public networks.

Multi-Link Aggregation and Load Balancing

SD-WAN supports hybrid access to multiple link types, including MPLS, internet, and 4G/5G. It dynamically distributes traffic across different links. A logistics company, for instance, aggregated three 100Mbps internet links into a 300Mbps bandwidth, achieving 95% utilization during peak hours. Additionally, if one link fails, it automatically switches to a backup link, enhancing network availability to 99.99%.

Multi-Link Redundancy Design

SD-WAN allows simultaneous binding of multiple network links (e.g., broadband, 4G/5G) and distributes data traffic across them. A multinational manufacturing enterprise achieved “zero records” of network outages in its Southeast Asian factories using SD-WAN. Another automotive parts company reduced device data synchronization latency from 5 minutes to 20 seconds through multi-link aggregation.

Millisecond-Level Fault Switching

When a link fails, SD-WAN switches to a backup link in milliseconds, preventing service interruptions. For example, a multinational enterprise’s weekly global team video conferences became smooth and uninterrupted after adopting SD-WAN, with no freezing or audio dropouts.
