DSLB | Farms

POSTED ON 3 January, 2018

The Datalink Service Load Balancing or DSLB, also known as Uplinks Load Balancing, allows to create high available and WAN scale of Internet Providers uplinks at layer 3.

The DSLB farm profile allows to create a routes based farm where the backends are uplink routers or gateways. This kind of farm profile is ready to share several uplink WAN router accesses using the load balancer as an uplink channel multiplexer (1 input and several router line outputs). Therefore, the DSLB farms could be used as high available communication links and additionally could be used as bandwidth scaling joining the amount of bandwidth between the routers backends links.

In the scheme below is shown the use case for load balancing several uplinks with different weights.
