Hello,
I have a serious problem with HTB which I wasn't able to solve myself.
I run a masquerading router with ppp0 as interface to the Internet.
Three clients need to share a downstream of 1 MBit, which I want
to divide

Still problems :(
I upgraded to kernel 2.6.9 now, configured IMQ to hook itself up after
NAT, called it
from prerouting, used u32 (matching works), set the root class to a rate
of 800kBit
(which is 200 less than my link speed) - and the behavior gets even
worse :(

I meant to delete the prio 1 - I don't know if it matters - I tested
with the other two.

Hi.
If the traffic from all the ppps leave by one interface then you could
mark packets by incoming interface and set up egress shaping with say
HTB on that interface.
There is only one eth0 interface to the internet and many ppp for the users.
So ... I have to shape every

Saying that I did notice that HTB was dropping -
maybe the default queue length is shorter now? It does seem a bit
strange though, I see drops where I expect the queue to be long enough
for my rwin and a class with two tcps on the go had less drops than one
with one

Folks,
I've been changing some of the classifier APIs especially bits
related to the rate estimator and statistics between 2.6.8
and 2.6.10. This probably broke some external classifiers
such as esfq. If you happen to use one of them just send
me the correspondig patch and I

I use overlimits as a counter in esfq - has this changed ?
I assume you're using your own tc_stats copy and not abusing
the policer stats. You may want to use the new statistic
interface which provides overlimits via gnet_stats_queue.
I used overlimits as it was always 0 for
