We want to get a second data circuit from a different ISP provider for backup purposes in the event our main circuit goes down. We recently experienced an outage that took 2 days to resolve. Since we have to pay for the second circuit we might as well use it. I want to get some type of load balancing appliance that would allow us to this. I had one vendor pitching a layer 2 device made by Elfiq. I have never heard of them. I was hoping someone could sugggest something.
