This article explains the necessary component to setup backup internet. Organizations which have multiple internet connection can use the solution to avoid any downtimes due to internet failovers. Internet load balancer can be used for the purpose. The below topology diagram shows how a load balancer can be used for the purpose. The available two internet connections are connected to the load balancer. The TP-LINK load balancer supports various WAN protocols supporting multiple internet connection types. Any link can be configured as primary and other link secondary. The users on the LAN network would connect to the internet through the primary link. In the event the primary link fails, all internet traffic would be routed through the backup link. The administrator of the network can configure the high speed internet link as primary and low speed as secondary.
