Load Balancing / Load Sharing over parallel paths

I have two parallel paths between a pair of routers. They are running
Eigrp between them. The bandwidths are very close to each other (704K
and 768K) so Eigrp Unequal cost load balancing doesn't really help me
because the traffic share count is usually 1 to 1.

I could get around this by altering the delay of one of the links and
then maybe have a trafic share count of 2 to 1.

I've tried per packet load balancing but because of the varying
latencies in each link, that doesn't work out too well for me.

What I would like to do is have a way of preferring the faster (less
latency) link until the bandwidth reaches a certain point, then
allowing the slower (greater latency) link to kick in.

The reason being is that sometimes 1 user will download a huge file
which will consume the entire bandwidth of 1 one link. Other users
will try to connect and because of typical per session or per
destination load balancing, they will attempt to also use the congested
link. I would like to avoid this. I want a way to set a threshold
for a particular link by % utilization, then put that link on hold
until the % util drops below a certain point.

If anyone sees what I mean here and has a solution, that would be
greatly appreciated.

Thank You

 

If the problem is a single FTP transfer, it sounds like weighted
fair queueing (WFQ) is not doing its thing. Could be because WFQ
has been disabled (or something about the configuration disables
it by default), or you may need to add traffic shaping on the links
to give WFQ a chance to kick in before the link is totally clogged.

Good luck and have fun!
