AI Technical Summary

Technical Problem

Existing VPN gateway implementations with multiple instances can cause unacceptable downtime due to improper configuration of VPN connections, leading to long delays in network traffic when one connection fails.

Benefits of technology

Reduces downtime to a few minutes or less, ensuring high availability and continuous VPN operations by maintaining active-active mode with backup instances, even when one instance fails.
