[LARTC] TBF + burst

[LARTC] TBF + burst

[js si]

I am using tbf to do rate limitation. i set the rate,
burst and latency parameters for tbf. but when i start
passing data i notice that there is an initial burst
and then the rate goes down to the configured level.
is this because tbf starts with a full bucket? 

thanks.

Well I suppose the burst starts full.

Remember if you are looking at tc stats then they show enqueue not 
dequeue, so you would see the whole buffer filling, but the dequeue rate 
will be lower.
