Link Load Balancing

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.

 

Link Load Balancing for High-Availability Network Connectivity

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 balancing helps guarantee uptime and service level agreements, reduce bandwidth costs and improve the end-user experience.

Array link load balancing supports five nines reliability and availability for applications, data services, Web sites and VPNs across multiple WAN connections, and allows aggregation of multiple low-cost links to reduce OpEx while improving connectivity. In addition, eRoute™ policy-based L4 dynamic routing directs traffic over optimal WAN links and ISPs for the highest quality end-user experience, based on preset and user-defined algorithms.
