What happens when the selected network path faces faults, quality degradation, or congestion? Global SD-WAN employs intelligent routing strategies to flexibly handle various scenarios, providing users with the best possible business experience through advanced path-switching mechanisms and in-tunnel traffic control technology. This article will delve into global SD-WAN’s path switching and in-tunnel flow control, offering a better understanding of how global SD-WAN ensures network stability and efficiency.

Path Switching

Global SD-WAN employs two primary methods for path switching. Firstly, there’s fault switching, which swiftly redirects to other compliant paths when the current connection is severed. Secondly, quality threshold switching allows automatic path switching when predefined quality thresholds, such as packet loss, latency, or jitter, are breached. This strategy ensures path stability in different circumstances, maintaining the continuity of user applications.

Once path switching occurs, international SD-WAN selects the highest quality remaining path for transmission, ensuring the user’s application experience remains unaffected. This intelligent path selection mechanism allows users in wide-area network environments to precisely perceive the status of business paths, achieving a more timely and seamless switching experience.

In-Tunnel Flow Control Technology

In bandwidth-constrained scenarios, international SD-WAN utilizes in-tunnel flow control technology to prioritize applications and balance traffic load. By defining application priorities, high-priority applications can utilize network bandwidth first, ensuring stable transmission for core business operations. This intelligent flow control technology effectively enhances the transmission efficiency of core applications, safeguarding the reliability of critical business processes.

In conclusion, international SD-WAN, through its path-switching mechanism and in-tunnel flow control technology, provides the optimal guarantee for user business experiences. Constantly innovating, SD-WAN is dedicated to exploring path solutions that better suit user networks and meet actual business needs. This effort helps users enhance the utilization of network resources, achieving the utmost reliability in business operations.
