PRIO and CBQ
Hi,
I''m work on traffic shaping and I would like to know if it''s possible to mix
differents Queueing Disciplines ??
I would like to combine the proporties of a PRIO discipline with that of a
CBQ discipline.
I read some documentation and I found nothing about that, can you help me ?
I think to try something like that :
tc qdisc add dev $DEV root handle 1: cbq …

HTB prio question
Hi all. I have a bridge running Linux 2.4.24 that I use as a
bandwidth manager on a broadband wireless network. I''m using HTB and
SFQ to prioritize that share bandwidth on a per-cell basis. My IP
tables rules divide the traffic based on IPand traffic type (using
layer-7 filter and ipp2p). My goal is to make sure that p2p traffic
on the network doesn''t sink all of the

tbf and prio blocking some flows entirely
I thought I had this all worked out, but it seems not. The following tc
configuration:

tc qdisc add dev ppp0 root handle 1: tbf rate 120kbit burst 1200 limit 1
tc qdisc add dev ppp0 parent 1:1 handle 2: prio bands 3
tc qdisc add dev ppp0 parent 2:1 handle 10: sfq perturb 20

Testing if tc works as configured and shaping rtp traffic
Hi,
I have implemented qos at my gateway, mostly for speeding up dns and
[video,voice] chat traffic and to slow down p2p traffic. It seems every
thing is working properly, as by browsing speed has been improved. But I
want to test it by sending various traffic and to see through which
qdisc the traffic flows, so that i can be certain that it is working
the way I want it to work.

problem with wrr+prio
I have set up wrr successfully on my bridge/shaper machine. That much
works fine. I originally used sfq in the inner classes. However, there
was a problem with high-bandwidth connections (web downloads,
bittorrent) starving low-bandwidth low-latency connections like ssh. I
would like to use prio or similar to prioritize the interactive traffic,
but it does not seem to work. I have tested with

prio and pfifo_fast not working the same?
I have a machine running 2.4.25 w/ wrr, ebtables-brnf, iptables CLASSIFY
and esfq patches (not using esfq, though).
I have wrr set up, and within each class I want to prioritize ssh, web,
etc..., but right now I am testing with pings.
I have the following in my POSTROUTING mangle table:
CLASSIFY icmp -- anywhere anywhere CLASSIFY set 0:6

Why arent filteres working? (as I wanted)
Here goes the filter statements:

Download ratio unstable
Hi, i''m newbie with traffic control. I create a script based in one from
Jason Boxman (thx a lot). the upload flow is prioritized well, but when i
download from a site, the down flow vary a lot from 25 KB to 4 KB. Before
i use this script the downloads are constant between 22 an 25 KB. Perhaps
there''s something wrong in my script ?
I paste it, thx.

classid, prio and position
Having a problem with classid and prio and position. Wondering if
someone could help? Below I have pasted a part of my current rules, now
it consists of one chain and two pipes. If they both use 60Kbit which
one would get priority? Would it be the one with the better prio or the
one with the lower classid or would it be the one which is first on the
list?

PRIO + filter problem
PROBLEM: My filtering rules don''t seem to be working in the latest
incarnation of my shaping script. I''ve changed from using multiple HTB
classes to just one and a PRIO qdisc, and now my filters don''t seem to have
any effect.
OVERVIEW: What I used to have is pretty much the same as the htb wondershaper
script (with some tweaks), which worked fine, but I noticed that my

LARTC problems with PRIO qdisc
Hi,
I have a router/firewall running Linux (like the most of you) and I
wanted to do some traffic control.
I''ve created an root PRIO qdisc like the example in paragraph 9.5.3.1
(http://www.lartc.org/howto/lartc.qdisc.classful.html#AEN903) with three
SFQ child-classes.
I wanted for interactive (ssh, telnet, ftp-control) and dns-traffic to

PRIO and TBF is much better than HTB??
Hello mailing list,
i stand bevor a mystery and cannot explain it J. I want to do shaping and
prioritization and I have done these following configurations and
simulations. I can´t explain, that the combination of PRIO and TBF is much
better than the HTB (with the prio parameter) alone or in combination with
the SFQ.
Here are my example configurations: 2 Traffic Classes http (80 = 0x50) and

SFQ latency
Anyone notices that using sfq qdisc adds latency compared to pfifo?
With "sfq perturb 10" ping latency is around 100-120ms, while with "pfifo
limit 3" drops to ~10-30ms (qdiscs belong to htb class).
I''m missing something or is this expected?
