Normally, if a customer has high available Internet connections and the Providers are supporting a proper load balancing, they will make use of BGP4 ( http://en.wikipedia.org/wiki/Border_Gateway_Protocol ) Border Gateway Protocol.

There is only one solution, you need to establish the load balancing by yourself. How we are doing this is by simple introducing a Link Controller. Now we are able to provide a high available and failover solution for outgoing Internet Traffic . But incoming traffic is still not load balanced. How should we do this?
