Server load balancing and failover requires the instant modification
of DNS records in order to re-direct inbound sessions to the
correct network interface. Our ActiveDNS module provides an
ISP Load Balancer module with the ability to balance traffic
between two or more WAN links and/or internal server resources,
thus speeding up access for remote clients, and improving server
redundancy in the event of either a network or server failure.

ActiveDNS is a major benefit when comparing
the Edge appliance to BGP (Border Gateway Protocol) solutions.
In addition to the cost and complexity advantages, ActiveDNS
also provides full inbound server load balancing capabilities.
This is something BGP can not easily offer, if at all in most
cases.
ActiveDNS & ISP Load Balancing can make inbound route changes
on-the-fly, and can load balance traffic in both round-robin
and dynamically weighted modes.
