How to use two Internet Connections at the same time ?

Hi .
We have a network with 11 PC's and we have 2 internet connections (ADSL Connection 512/128 & Cable Connection 512/64) is it possible for using these connection at the same time (downloading a file with a speed of the booth connections 1024/192). Our network map image is: Network Map !!! PLEASE FOR HELPP!!

Another way is connect the two external connections to one of your computers using two NICs and that computer do the routing (will end up using 3 NIC total). Routing software can then keep track how much traffic is going through each link and choose the best path to use. Since you have so many computers and NICs are inexpensive… this might be cheaper for you than a getting a dual WAN router?

Look at http://www.zebra.org/. I tried OSPF routing with zebra for this sort of stuff for a short time but haven’t touched it for awhile…

I don't know about the plumber analogy... Can also be viewed as calling a plumber when all you need is replace a washer to stop the leaking.

Anyways, is really for Dime to decide plus we don't know what kind of services (if any) are running on those computers. If Dime already got a Linux box running some services and it can take the load of routing, why not?

Off the shelf networking products are easy to use and generally reliable but just remember you are trading control for that.

All Computers is running on WinXP Pro Service Pack 2 and to point that one connection is in one bulding and the second connection is in different building!! I heard that Win Server 2003 could make this problem working!! Any other sugestions??
