Multiple IP setup

[BryanM]

Just wondering here, had some spare time, so i thought, if you had a network with multiple IP address's, meaing 2 different cable lines with 2 different modems, could you setup a network and in thery download and upload twice as fast. I know the idea sounds very simplistic, but does it work? What sorts of hardware would you need, and ofcourse, how hard would it be to do.

You would need some routers that are more powerfull than the standard Linksys, or Actiontec etc..

You would need to set up the router so both networks could talk to each other. Once this was done, you would need to set up sharing for the two lines. Maybe some sort of QoS type function.

I have only had things set up this way: we have a T1 and DSL. They are setup to operate opposite of each other. If the T1 is down everything goes to DSL. Once the T1 is up everything switches back to it.

We have some V Lans setup on our switches that allow specific network conenction to use DSL directly without the computers actually connecting to our main network.

You need a dual wan port router to do that. you can't just connect 2 modems to one computer and expect it to do load balancing.

Xincon makes relatively cheap dual wan port routers. I've heard they are better than the Linksys dualies. I think Newegg had 'em for around $85.

There are inexpensive Dual WAN Routers (as mentioned in the above post) but these Routers Do Not combine the Bandwidth. They can be set as Fallback, or to use the fastest available connection, but it would NOT combine the Bandwidth.

It does not matter what you do, in order to combine two broadband services to create One Double Fast Connection, you need Signal Sync. at the source (ISP), and if there is No Sync at the source you get two independent signals that do not know how to relate one to the other.

There are few ISPs that provide this service (i.e. they will feed you with two lines in Sync.) but naturally it is expensive.

If you buy your own two connections to the Internet Backbone you can use special Server software to create double "Speed" (the software goes for Thousands $$$).

yep. what he said. :cool: dual lines are for redundancy and load balancing, not to "shotgun" your connections.

Here's a review of the xincon I was talking about. that should help explain it.

That was the term I couldn't think of before when I said QoS.

I wasn't thinking in terms of shotgunning the connection as it was put in the previous posts. :)

Notice this caveat: “In order to shotgun the two broadband connections, the use of a download manager is necessary”.
If I understand it correctly it can improve downloads of files that are offered in multiple servers.

Depending on the scheme of the Download program it can take parts of a file from different servers using each connection for part of the file.

However it is Not Combining the bandwidth. If I put a file on One Server Only the download will not double.

This capacity via smart download program is not bad, but it valid only for downloads, and the download file has to be offered by few fast servers (notice that the server used in the example is Microsoft.com). If I put a file on one server only the download will not improve.

P.S. The same program Download Accelerator might improve dramatically downloads via one Internet connection.
