Don't expect good quality if use local QoS for incomming
data. To have real non-best effort you need to have QoS
on both sides of link - when transmitting packets.
Then yes - HTB should be able to do it using priorities.
But I doubd you can do it if IMQ is in the way.

You can use only one
tc filter add dev ppp0 parent 1: protocol ip prio 1 handle 1 fw
and set classid directly in iptables like:
iptables -t mangle -A to-dsl -p
The other thing that is current sub-optimal is the division of long uploads
vs short uploads. I've attempted to ensure that normal webpages are
downloaded as fast as possible with the burst parameter but if someone is
downloading a large file from my website all other web users suffer. I've
it is not possible to attach qdisc to inner node. If you
do it it is deleted when you create 10:5 ..

Hi there!
If I use a structure (with HTB) like this one:

Sould I only use sfq on
Otherwise iptables will do the whole to-dsl list for every packet. In
your case ot wouldn't matter except for some extra CPU usage. But if you
would like to mark port 80 as bulk-traffic and ACK's as interactive
traffic, then those port 80 ACK's could be marked as bulk which you
wouldn't
Hi it seems as if there is something other throttling
the data - is not it the case that you tested the downloads
thru your 128k internet connection ? If yes then throttling is
done at other side of line. The try to set BAND to 110k for
example ...

Im playing with HTB and police filters. It seems that the drop action
doesnt work with htb (I think it sends the traffic to the default
configured class).
ohh yes you are probably rigght. I'll try to make it better in
the nest release.

Thanks for the answer.
Now correct me if I got it right, what you said it is a tc bug? Because it
looks for the filters like you said ? I mean the kernel doesnt have all
those filters, right?
well it is really bug in kernel in show part. But yes it is
only cosmetic bug - kernel have only one
nice to see another active developer in field !

I thought about changing qos subsystem to support real ingress queueing
without imq or something. Kind of two root qdiscs per device. What do
you
(and others) think about this ?
There already is
So, is it a bug, or a misconfiguration ?
Sorry about that, it IS a bug :(
It has been fixed and i will put out a new version tonight.
The problem was that packets passed through non-work-conserving qdiscs
were delivered to dev_queue_xmit_nit twice and somewhere there a NULL
pointer

with wget or lynx - netscappe | IE tries to be too

What says file tc.gz about downloaded file ?
What is the size of the file ?

the rate is really measured - it is used as source for DRR weight
(here it is used relative to other classes) and to see whether we
need to borrow from parent - here absolute value matters.
So that the example above should work and give 512k.
So each class gets it's rate if it can by
Yes. Patch SFQ to use only IP in hash and no port :)

Hi Folks,
Is there a way to deal with download accelerator programs, such as

all are used everytime.
you have to use filters to direct unneeded packets
into fake queue (X:0 in case on HTB, some hiprio
band in case of prio ...).
