[KLUG Members] Load Balancing Solution for Multiple ISP Link

[Komal]

Hi
Here is typical requirment 

We need a a Load Balancing Router for aggregating the bandwidth of our
multiple ISP Links with Failover and Redundancy feature. 

This Linux based Load Balancing Router should have the functionality
described below: 

1. This router should act as a gateway for our LAN and all our internet
traffic should be routed through this. 

2. In the normal condition when All the ISP links are active, it will
distribute the internet traffic between the all links so that all the
ISP links can be used equally or in a pre-determined proportion, thereby
achieving Load Balancing. 

3. In case of failure of one of the ISP Links, it will do an automatic
transfer of entire internet traffic to the other links within a couple
of seconds, thereby providing Failover as well as Redundancy. 

4. The router shall also restore load balanced status as in (1) as soon
as the failed link becomes alive again. 

5. The incoming traffic for our application and other servers will be
divided between the all Internet links and in case of failure of some of
the links, it wil be automaticaly shifted to the other link. 

The load balanced status shall be restored upon restoration of the
failed Internet link. You shall implement a Dynamic DNS for our domain
to achieve the features described in (5). 

Regards,

Komal
