Protecting Network Continuity against WAN Outages
Enterprise WAN plays a key role as more enterprises today rely on it for business operation. A high-speed and reliable internet connectivity is required for almost all business in the world. Some enterprises deploy multiple WAN links that are often provisioned and work as separate links. One may be an active link while the other stays idle as a backup, resulting in inefficient utilization of the bandwidth resource.

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

WAN Failover & Failback

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

Better WAN Efficiency through Load Balancing
>  WAN 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 is incorporated to help the appliance find the most active and responsive link for traffic distribution. Outbound load balancing works in conjunction with path-monitoring, which constantly gauges the status of all WAN links. Based on the measured result, the selected algorithm efficiently distributes traffic across available paths and avoids sending traffic via the paths which are either down or slow.

WAN Load Balancing

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