Load balancing.
Hello I was wondering if there is a way to load balance between 2 different ISPs. If I were to have lets say a cable internet connection with 3mbs down/up and a DSL internet connection with lets say 1mbps down/up is there some way of combining these two links logically and gain some internet speed?
I have 3 cisco catalyst switches at my disposal if that helps.

You can do standard load balancing and weight the connections according to there speed. This will allow you to download two files, one at 3Mbps and another at 1Mbps. You will not be able to download at 4Mbps.

But at any given time, I'd be on 1 IP or the other. So let's say I open a browser and head over to revision3.com, I'd either be over the 3mbs link or the 1mbs link. And then what if I have a link to a website and all of a sudden I'm switched over to the other link and my connection to the website is severed? I guess my question is, is it practical? Will it work smoothly?

In most circumstances it will work fine. it will only not work fine when a web site cares which IP you have.

You could implement least cost routing tables in the cisco gear.
Set the DSL link for low rarity stuff you can happily do in the background, and keep the Cable for interactive content. (Sorry - not a Cisco tech, only know that we had it done with our routers and T1 lines for VoIP priority).

I found this website that does load balancing via their servers. I haven't used them but it seems like a cool idea.
http://us.sharedband.com/ Also meraki has a router that does this type of load balancing and fail over out of the box. Who needs Cisco.

It's not done on their servers, it's done on the routers, with a custom firmware.

I thought it was sort of proxy thing where the custom firmware is only meant to keep sync with a server that is redirecting traffic. If it's not then I stand corrected.
Yes you can do cost based load balancing and all that stuff but I don't think any of the available routing protocols take into account available bandwidth which changes constantly. Also certain applications and websites will not work if the traffic is split into two different ISPs because my public address changes depending on which ISP the traffic flows through (as I understand it). I'd need a protocol that is smart enough to know that if I am making a phone call I need that traffic to stay on the ISP it is currently running through. This Shareband takes care of all that, I am assuming.

Most of your better routers will allow you to have multiple sources. Even some of the bsd firewall distros for white boxes specifically support it.
VYatta may also. http://roggyblog.blogspot.com/2009/1...atta-vc-6.html
