Hi Stef and Alexey
I have read some documents about CBQ algorithm from
http://www.icir.org/floyd/cbq.html
but still have some question about CBQ in
Linux
.
1. First estimator can estimate how much bandwidth already USED per class. one estimating algorithm is EWMA (exponential weighted moving average), how about Linux implemenatation about estimator? also do you have link for this algorithm? I canot find it. 2. If I want to see how CBQ work in Linux, any suggestion how I start read these code? there are a lot of files under tc folder, q_cbq.c tc_cbq.c... 3. In linux how CBQ measure used bandwidth per class? does it measure bandwith bits/sec? If it measue bandwidth every seconds, is there any way to collect these data (grap these data)? 4. I read stef's monitor.pl, it is based on firwall
code. why didn't use CBQ's measurement result if it can do (I am not
sure..)?
5. In stef's bandwidth monitor, I am not sure
whether it is per-flow based or per-class based. if it is per-flowed based, how
can I modify to per-class? I belivee CBQ can estimate used bandwidth PER
CLASS.
For example you have two flow belong to one
class.
6. In Linux how CBQ distribute the excess bandwidth
between sibling class
when "borrow" enabled. what algorithm it used? which code? 7. Can HTB do the same job as CBQ right now,
can HTB do borrow ?
Thanks in advance
best regards
