Configuring Bandwidth Load Balancing

Overview: Configuring bandwidth load balancing

This functionality is not currently available in the U.S.
You can configure BIG-IP Link Controller to use bandwidth load balancing to manage the traffic flowing in and out of a network. In bandwidth load balancing, Link Controller uses a specific link until a traffic threshold has been met. After that threshold is met, the Link Controller shifts traffic to another link. When the traffic falls below the threshold, the Link Controller shifts traffic back to the first link.
The following illustration shows a network for configuring a bandwidth load balancing configuration.
Example of a network for configuring bandwidth load balancing
As the illustration shows, the most cost-efficient configuration is to have the Primary Link handle traffic until it reaches a certain level (for example, 50 Mbps), then send any traffic over a certain level (for example: 50 Mbps) to the Secondary Link. When the traffic decreases, the Link Controller must switch back to using only the Primary Link again.

Implementation result for bandwidth load balancing

You now have Link Controller configured to use bandwidth load balancing to manage DNS traffic.
