Some doubts regarding load balancing!!!

[joy charles]

Hi all,
I have implemented load balancing using the tutorial http://www.ssi.bg/~ja/nano.txt ..The traffic is going through both my external network interface.

I have some questions regarding this:

ip route add default table 222 proto static \
nexthop via GWE1 dev IFE1 \
nexthop via GWE2 dev IFE2

The author explains the kernel chooses both the interfaces
alternately (weight being 1 for both). Can anyone please
elaborate this, like how the kernel will decide this???
Will it decide using any hash functions???

Is this kind of loadbalancing similar to ECMP (Equal cost
multi path). Please let me know..

Thanks,
Joy
