Dual WAN Router(s)

What's the difference between a WAN link controller and a dual WAN router?
A dual WAN router uses simple policy to "route outbound-only traffic" over one of two lines. There is no intelligence in the technique and no method to avoid or minimize congestion. In fact, the rigid nature of the technique frequently adds to congestion problems. Additionally, a dual WAN router does nothing in terms of load balancing and failover for inbound traffic. PowerLink™ WAN link controllers are hardened devices that are located between the firewall and the LAN, and use a more up-to-date architecture based on Network Address Translation (NAT) and Dynamic Domain Names Service (DNS). They are designed for small and medium enterprises who can't afford the expense and overhead of multiple routers, and the heavy demands placed on them by ISPs for using BGP.
