Protocol Bindings: Refer Section 3.4.3 for details
Load balancing is particularly useful when the connection speed of one WAN port greatly differs
from another. In this case you can define protocol bindings to route low-latency services (such as
VOIP) over the higher-speed link and let low-volume background traffic (such as SMTP) go over
the lower speed link.
