Messaging has rapidly become the one, true business critical application in use today by many, probably most, enterprises. Even more so than Enterprise Resource Planning or other cross-business applications, any failure in the messaging system is noticed by, and affects everyone. If a person cannot get an e-mail to or from another person then they are immediately in contact with the help desk to report the problem. Users are far less inclined to be forgiving when it comes to an e-mail outage; they just expect it to work.

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).
