VPN Redundancy Ensures Greater Productivity and Protection of Vital Assets

VPNs are critical network links that allow external employees, road warriors, customers, and partners to access your networks. However, even the expensive redundant VPN systems are vulnerable to WAN bottleneck and service provider outages.
WAN link controllers are an affordable network load balancing solution for ensuring the reliability and high performance of VPNs. They combine the use of two or more ISP connections to create multiple paths for VPN tunnels, improving site-to-site performance and ensuring automated failover in the event of a network outage.

VPN failover: A load balanced VPN using redundant Internet access directs traffic among multiple Internet connections through a technique called multi-homing. When one link goes down, WAN and ISP failover solution automatically switches Internet traffic to an appropriately functioning link. When a WAN link controller such as Ecessa’s PowerLink™ detects a link failure it automatically switches traffic over to a functioning link. To eliminate the chance of the PowerLink being a point-of-failure, PowerLink provides for device failover through its active/passive failover hardware capability.
