Hello,

I have seen in my site something strange. I use tc-CBQ for bandwidth
shaping, and it works properly well. Sometimes i have seen UDP connections
spend more bandwidth than i set up to the user. I have 4 sites, and it
always happens. Is there a problem with bandwidth shaping and UDP packets?

I have never used CBQ. It could be that you are measuring the bandwidth before the queue - UDP won't usually back off in response to delay/drop like TCP does.

Andy.
