similar to: Installing HTB and CBQ

Hi, I am looking working (!) qdisc that would guarantee preferential treatment to priority (ex voice traffic). It is supposed to work as LLQ (Cisco) which means it is PQ but with bandwidth limited for EF PHB traffic. I did lots of tests with CBQ and prio set to 1 for EF PHB and prio 2 for best effort. Although delay does not look like being guaranteed at all for priority traffic. Eventually I

Hello, Does anyone know when one should use cbq versus (simpler more accurate) htb? Specifically does cbq have added functionality that may be of interest to certain applications? from htb home> Both CBQ and HTB help you to control the use of the outbound bandwidth on a given link. Both allow you to use one physical link to simulate several slower links and to send different kinds of

Hi all, Can anyone in this mailing list answer a few theoretical question which r confusing me. Here is the scenario I have a total Bandwidth of 2Mbps for a private LAN I am managing. I am using cbq standard script available online and for controlling bandwidth, squid and iptables. I have diff. packages for client. One: server own services access (unlimited bandwidth means no delays or

Which diference of I to use the CBQ and the HTB? I need priority a many ports.. same ports are 5060(voip),25(mail) and 3128(squid) It''s a my example off cbq arquive : DEVICE=eth0,10Mbit,1Mbit RATE=500Kbit WEIGHT=50Kbit PRIO=5 RULE=:5060 BOUNDED=yes ISOLATED=yes I need specific a rate or is not!?

Hello Thilo, What did you find superior with CBQ-wondershaper over HTB-wondershaper? We have not been using wondershaper specifically but our simple tests so far seem to show that htb is much easier to configure for a given target shape (i.,e accurate) compared to CBQ.

Hello, I''am successful using a linux (2.4.20) bridge and the cbq.init_v0.7 script for traffic shaping. But I can only use the queuing discipline tbf (LEAF=tbf). If I try use queuing discipline sfq or none then tc applies the rules but no shaping occurs. Is this problem a normal behavior when using bridging ? I tried to use htb.init (using patched tc binary). It accepts the rules but

Hello all. I''ve been struggling to QoS VoIP at our site and have a successful implementation at this point. Basically I had to set aside enough bandwidth for VoIP by placing all other traffic behind an HTB (multiple classes and queues behind it). Everything is fine. Here''s the diagram: ------- | eth | ------- | --------

Hi all , does Kernel 2.4 supports CBQ and HTB by default or we have to recompile it. Regards Fahad Khan _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

Hello all, I am testing CBQ and HTB these days and I got a lots problem which needs your help. It is a little long text :) Thank you! (All my test is based on Redhat Linux9.0) 1.Is isolated of CBQ working? I have read Mr. stef word that he never made cbq isolated work. 2. I have setup an environment to test cbq: one tcp flow which I should protect and a noisy udp flow who will eat much of the

Ok, this has been kicking my @$$ for weeks. I'm trying to get some kind of bandwidth shaping working on my server. I need to throttle ftp down so as not to suck up all the available bandwidth. I had cbq working on the old server (an ancient RH 6.2 box) so I figured I'd just move the config over and get cbq.init from sf.net and it should work. Unfortunately it doesn't. At least

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

Hello all, this is my first post here. Sorry for my english. Gentoo LAN router, 2.4.26-hardened-r2 There are 2 WAN links, one LAN link. I am doing some iptables/routing/tc magic in my scripts. What''s interesting is marking packets traveling from all IP''s in LAN. Interesting commands are: ------------- for ip in `seq 50`; do $IPTABLES -t mangle -A FORWARD -o eth2 -d

About the cbq.init. Four machines which traffic to limit in same LAN. Is the samething if I put limiting rules to four different files or all to the same file? Like: DEVICE=eth0,10Mbit,1Mbit RATE=64Kbit WEIGHT=6Kbit PRIO=5 RULE=192.168.0.5 RULE=192.168.0.6 RULE=192.168.0.7 RULE=192.168.0.8 OR four equal files with different IPs, Ids and no PARENT rule? What style of ID numbering you use if

If I create a cbq qdisc as a leaf of a cbq class, the bandwith rate is the same of the root cbq qdisc or the rate of the cbq class? Does exist the parameter rate on the "tc qdisc add" for cbq command? tc qdisc add dev eth0 root handle 1:0 cbq bandwidth 10mbit avpkt 1000 cell 8 tc class add dev eth0 parent 1:0 classid 1:3 cbq bandwidth 10mbit rate 50kbit allot 1514 cell 8

Hi list, playing around with HTB showed that it may introduces pretty much latency for our setup. Docum.org says the following: "The default qdisc added to a htb class is pfifo_fast qdisc. The size of the qdisc is the device queue length and this is 100 packets for an ethernet device. So if you want to have a shorter queue, you have to add a shorter qdisc to the htb qdisc." Can

Hello everybody! With a HTB qdisc: # tc qdisc add dev eth0 root handle 99: htb How can I change the "final qdisc" of the default walk-throught class? # tc qdisc add dev eth0 parent 99:0 handle 88: sfq results in: "RTNETLINK answers: Invalid argument" CBQ automatically creates a xx:0 root class where I can attach final qdiscs... - If there is a root class in htb, how is it

Hopefully someone has a suggestion on how I might do this...as I can''t figure it out :( I need to be able to set up a group of seperate users who have a "bandwidth pool" they share, but also be able to limit their individual bandwidth as well. Example: I have 5 customers and would like to be able to provide them with a maximum of 256Kbit each, with a CIR of 33%. To do this,
