Re: [LARTC] how to determine tcp rate & classifying packet info

[Jesper Kold-Hansen <candyman@cs.auc.dk>]

Well red the doc on the cues. I know on the HTB que, there is a rate and a
coil setting. The rate is the rate at wich the packegges are sendt in
kbyte, and the coil is a burst funktion, so if you set the coil and the rate at
the same speed you vil get a specifik rate that your packagges are send.
But it is not easy to controle the actual rate, because when you set a
rate, you actualle drop tcp packagges, the the protocol will slow down by
it self.

Look at the Advanced Routing howto.
