If you are shaping from the "wrong" end of the bottleneck then you need to back off from link speed to get control - and it still won't be perfect.


It's best to priorotise interactive traffic and not mix it with bulk traffic.

Because numflows is dynamic, I'm not sure how I would have the bandwidth allocated to each flow change dynamically and automatically as flows are added and removed.

Anyone have an idea how to implement this? Thanks.
