Re: Internet Traffic load balancing

Yes, but ...

Maybe you have found different, but in my testing PFR does not provide the
fail over and fallback well enough. It also does not perform unequal load
balancing ... I believe the goal for this was 70/30% distribution over both
links ...

You can use it to learn delay, packet loss etc ... and then choose the right
link. Of course PFR is using IPSLA under the hood as well ... so it is
powerful.

I do not believe you can use PFR for tracking and reporting on total
throughput / usage.

The main reason I did not mention it, is due to the mention of load
distribution and fail over / fallback. Perhaps my testing was not as finely
tuned, and I found the details confusing ... have you found it to do well
for this?

I appreciate your input!!!
