F5 BIG-IP Link Controller 2000S - load balancing device

Your ISP connections are your link to the outside world. Having multiple connections can increase availability and performance, but managing multiple links can be difficult. BIG-IP Link Controller puts the management of these links under your control. It monitors the performance and availability of each link and directs connections - both inbound and outbound - over the best possible link. It also improves application performance by prioritizing and optimizing traffic. BIG-IP Link Controller gives you the tools to direct traffic over the most cost-effective connections first so you can keep your ISP costs at a minimum.

The result is more effective use of multiple ISP connections for greater reliability, better performance, and lower costs.
