Protecting Network Continuity against WAN Outages
Enterprise WAN plays a key role as more enterprises today rely on it for operation. A high-speed and reliable internet connectivity is required for almost all business in the world. Some enterprises deploy multiple WAN architectures in an active/backup fashion, in which one may be an active link while the other stays idle as a backup link. This might result in inefficient utilization and waste of the bandwidth resource.

Outbound Failover & Load Balancing

>  WAN Failover & Failback
Network downtime means user frustration, lost productivity and decreased revenue. A short interruption can even have significant impacts such as dropped VoIP calls or disrupted application sessions. The major tasks for WAN failover is to help enterprises build a network that never fails. WAN failover ensures enterprise a unbreakable WAN connectivity in almost every situation.

By properly configuring automatic WAN failover on the appliance, the continuity for business networks is thus guaranteed. The mechanism works in conjunction with path monitoring, which constantly monitors the status on all WAN connections, and so is able to mark faulty links as inactive and remove them from the pool immediately. Traffic will then be sent across the remaining active paths as WAN failover automatically diverts traffic from the path(s) marked inactive. The mechanism of path monitoring continues to monitor the failed path(s) and marks them back active once they failback. WAN failover provides 99.99% network uptime, and maximizes business continuity and employee productivity for business.

Better WAN Efficiency through Load Balancing
>  Outbound Load Balancing
Outbound Load Balancing helps business cost-effectively build a reliable and fast connectivity through traffic distribution across available paths. A variety of algorithms are incorporated to help the appliance find the most active and responsive link(s) for traffic distribution. Like WAN failover, outbound load balancing works in conjunction with path-monitoring as well. Based on the measured result, the selected algorithm efficiently distributes traffic across available path(s) and avoids the paths which are either down or slow.

The ability to harness existing and newly added WAN links enables enterprises to incrementally increase bandwidth capacity as the demand grows. Better user experience will be delivered as the best-performing and least-loaded WAN connection(s) is always selected for traffic distribution.
