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

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 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

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/

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

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

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.

I find the negative attitude toward CBQ to be distracting and non-professional in the HOWTO. I''ve re-read it for the first time in about a month and comments like "This can be configured in a variety of ways, which I do not understand. Use HTB" do not encourage me about the writer. This is not a personal critique, as I can imagine this being said on a personal website,

While I''m thinking about that review of howto changes, here are a few other responses about things I don''t believe. I''ll be interested in more info if anyone has any. ==== [from new doc] Besides being classful, CBQ is also a shaper and it is in that aspect that it really doesn''t work very well. It should work like this. I''ve not noticed that it

Hi, In my LAN Iam trying to make following setup: - All the traffic generated by 10.0.2.1 should go to 10.0.2.11, If the destination of this traffic is internet than it should be placed on its interface eth1. Outgoing traffic on eth1 should be shaped.For this I am using fw filters and cbq. _______ 10.0.2.1 -------> 10.0.2.11(eth0 )----| A

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

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, 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

The manual says (about prio): > Because it doesn''t actually shape, the same warning as for SFQ holds: > either use it only if your physical link is really full or wrap it > inside a classful qdisc that does shape. The latter holds for almost all > cable modems and DSL devices. I want to wrap prio inside of tbf. Here''s why: I have a server on a DSL line, which has

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.

Hi, The CBQ config file shud be some thing like this. DEVICE=eth0,10Mbit,1Mbit RATE=50Kbit WEIGHT=5Kbit Shall i hardcode the DEVICE BW as 10/100 Mbit or Shall i use any other tool like ethtool for getting this. ethtool gives Speed: 10Mbps If so, how about, if i use some other Interfaces other than eth0, like ppp0 or some other? C''d anybody can give a suggestion over this? thanks
