>From an NSP perspective when you have a saturated upstream link and you
need to "slow" down some, umm, unwanted traffic, would a prudent person
custom/priority queue the interface or would rate limiting be the answer.
If I re-queue the interface the traffic could still find it's way on the
upstream or downstream links. If I rate limit the interface it turns into
a cat and mouse game trying to find the sweet spot that allows the service
through but at minimum throughput levels. I'm currently leaning on
re-queue the interface because one I'm old school and two once I set the
queue strategy, I don't have to micro manage every network interface.

I'm really looking for some pros and cons that I haven't thought of yet.
Have I missed a really big reason due to direct involvement blinders. In
which case I need to wear a dunce hat for asking such a silly question?
