PowerLink and ShieldLink site-to-site channel bonding provides the ability to bond multiple Internet links into a single high-bandwidth channel for uninterrupted availability for applications that require site-to-site connectivity. If one WAN link goes down or degrades in performance, traffic is automatically directed to the best working links without interruption. Channel bonding is a form of load balancing which allows for stateful failover of traffic to the best performing links to ensure critical applications avoid problems that occur when they are stopped on one link and restarted over another link. Site-to-site channel bonding ensures that critical applications avoid WAN failures, and are not adversely affected, even after brief disruptions.

Site-to-site channel bonding supports applications that are bandwidth-intensive such as images. These files may be sent over an open connection, or transferred through a VPN connection to remote locations. Transfer time can be dramatically reduced by combining multiple WAN links, while preventing the need to re-transmit files due to a WAN link interruption which may drop the VPN connection. By adding additional bandwidth connections at a remote location, and incorporating a PowerLink or ShieldLink 200 at each site, you can bond the bandwidth of multiple links to increase the aggregate throughput – dramatically lowering the transfer time. With multiple Internet paths, you can also ensure file transmissions continue even if one of the links fails.
