WAN load-balancing routers

I got an offer for $20/month broadband access from Centurylink. It got me to thinking, could I somehow use that as a backup connection to my current cable ISP? How would that work? Could I use a Raspberry Pi as a WAN load-balancing router?

The details
Well I’m not sure about using Raspberry Pi. It’s not so simple.

But I just wanted to mention there are solutions out there in the marketplace to this very problem. They’re not that easy to find, hence this article. They’re mostly aimed at small businesses where Internet connectivity is very important, like an Internet cafe.

This Cisco dual WAN router for $157 would do the trick:

Or for about the same price, this Linksys Dual WAN router:

Want to go consumer grade and save money? This TP-Link model is only about $85:

But it’s ports are only 100 mbps, which is kind of surprising in this day and age.

We have identified commercial solutions to the question: can I use two ISPs at home to provide high availability and load-balancing. I’m not yet sure about a Raspberry Pi solution.
