[nsp] QoS use on ATM

It sounds like you want shaping and not smoothing, so it's not really QoS...
CAR is your best bet... You can change your IP Precedence, which is probably
what you don't want if you're paying for the burstiness - so I'd just go
with "drop" - it'll slow things down but if it's mostly TCP based you won't
notice as it should back off...

Subject: [nsp] QoS use on ATM


I have an ATM DS3 connected upstream that I get billed for based on the 
amount it is used.  What I want to do is "clamp" it so that no in/out 
traffic can exceed a threshold of x Mbps.  What is the best type of QoS to 
use for this purpose that is the least disruptive to the traffic when I 
actually hit that threshold, but still keeps me from exceeding it?
