Load Balancing Switches

Posted on 2009-05-19
Last Modified: 2012-05-07
I have 2 t1's and 2 firewalls.  I'm looking to load balance the 2 t1's.  As I realize the firewall can do this, my firewall also has filtering software for spam and IPS as well as web blocking and my boss  is concerned that this will cause a bottle neck instead of relief.  So I'm looking into a switch that I can plug the 2 firewalls into and load balance on that.  Does anyone have any suggestions as to what to use?  We are looking for something affordable.

We use one of these where I work.

you put this in front of your firewall but behind your routers and it will load balance the T1's coming into your network.

this allows you to load balance?  I need to be able to just pull the bandwidth if necessary. Also approx how much does this cost.  I'm looking into the Cisco 2960 layer 2 switch.

Yes, this allows you to load balance between the two T1's. I don't think it's possible to aggregate the bandwidth between the 2 T1's seeing as they are independent of each other. You will only have a max of 1.544mbps not 3mbps because they are separate connections, you will just have more available bandwidth to your users at 1.5mbps.

Oh and I'm not sure on the cost, I was not involved on that project. It can't hurt to give them a call and see what your options are.

Basically that's what I want.  I realized that I can't have 3 mbps.  I'm just looking to "borrow" from the other side and give it back if necessary.
