Link Load Balancing for Highly Available Network Connectivity


Link load balancing provides advanced failover and bandwidth management for multiple WAN connections to assure continuous operation of enterprise applications and cloud services in the event that one or more ISP links become unavailable or slow to respond.

Array link load balancing intelligently analyzes ISP WAN links to allocate bandwidth, assign priority and enable seamless failover for business-critical applications. Available as a stand-alone solution or in conjunction with other Array high-availability solutions including server load balancing and global server load balancing, Array link load balancers help guarantee uptime and service level agreements, reduce bandwidth costs and improve the end-user experience.
