Bonding/Load Balancing With Linux...

caps_phisto · 08-22-2006, 09:30 AM

Hello,

Here is my scenario:

I have three lines from my ISP (all High Speed lines). I have a Linux Box (Slackware 10.2) in between them and my internal network.

What I would like to accomplish is to "bond" or "balance" my outgoing and incoming traffic over the three links as equally as possible.

I have read this following article and I believe that it would suffice for my needs:

http://www.linuxquestions.org/questi...ancing+network

Am I correct in assuming that if I were to "bond" three NIC's in my Linux Box that what I would like to accomplish would work?

Thanks in advance

no, you wouldn't do a bond. you'd bond the nics if you wish to combine their throughput and other features on a single network. you still only go from point a to b, but you have a freeway instead of a single lane to drive down... kinda.

check lartc.org chapter 10 for isp load sharing.

I read the article that I was direct to, but I don't think it's explaining the same situation that I have. This is my situation:

Code:

                 +-------+   eth1   +-------+
                 |       |==========|   C1  |
 'network 1' ----|   L1  |          +-------+
                 |       |   eth2   +-------+
                 |       |==========|   C2  |
                 |       |          +-------+
                 |       |   eth3   +-------+
                 |       |==========|   C3  |
                 +-------+          +-------+

Where:
network 1 = internal net
L1= My Slackware Box
C[1-3]= Comcast provided modems

How would I implement load balancing to all three modems from my one box?

would the balancing work or am I just reading the chapter 10 article incorrectly?

Thanks again.

pants sorry, half the answer to these questions is chapter 10, the others are chapter 4! http://lartc.org/howto/lartc.rpdb.multiple-links.html
