# Test with bonding gbit lan ?^-Super_Treje-^ 2010-05-03 23:34
No test with the network in "bonding" ?

# I did, but....BruceBruce 2010-05-04 07:15
I repeated the tests with IEEE 802.3ad Link Aggregation Control Protocol, using two Intel Gigabit CT Desktop Adapters in the test bench system. The problem with that test scenario and Teaming or Bonding or whatever you want to call it, is that the network speed stays exactly the same. The bandwidth is increased by widening the data path, not increasing the speed. I.e. it?s analogous to two fully loaded trucks driving the speed limit instead of one truck delivering your data. Yes, you get twice the data, but you get it in the same time frame, which is what our testing measures.

I think the way to test this feature is to have two or more transfers occurring at the same time. With one transfer already under way, another could be started and timed, and the speed of the second transfer should be relatively unaffected by the continued activity of the first one. Your thoughts, suggestions?

# 802.3ad is NOT your solutionscavenger 2012-11-30 12:01
YES this is it. Load balancing is made only on multiple file transfers.

If you can read french, I posted a lot about it on #lafibre.info/iperf/gs108t-nc360t-n5550-load-balancing-33mbs/new/#new but the result is this one :
Conclusion is 802.3ad is ONLY failover. ABSOLUTELY NOT load balancing.
If you want to do what I dreamed of, choose on each side the Balance-SLB (or Balance-ALB) + round robin transmit load balancing method.
Then you will have a smooth repartition of the packets on each port, but you will notice a strong down bandwidth due to the fact that "Packet order is NOT guaranteed"
Load balancing for a one file transfer on many cables is just a dream... right now...
