Enterprises with mission critical applications are exploring the benefits of disaster recovery sites for their data centers to ensure business continuity. Special network technology is needed to ensure that site failover and failback occurs reliably and predictably. An ideal solution should provide reliable network connections, manage inbound and outbound traffic over multiple WAN links, failover to a secondary data center if all links at the primary data center are down, and eliminate deployment barriers and costs of multi-homing with BGP (Border Gateway Protocol).
