Hello everyone, I''m a newbie experimenting with CBQ shaping and am facing a few problems. Can any of you please help?

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

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

Hi all, I''m having some problems setting up qdiscs on a bridge.The config looks a little like this: ifconfig ifb0 up # Bring up the IFB for this bridge. tc qdisc add dev eth2 ingress tc qdisc add dev eth3 ingress tc qdisc add dev ifb0 root handle 1:0 cbq bandwidth 100Mbit avpkt 1000 cell 8 # Raw qdiscs on each bridge port tc qdisc add dev eth2 root handle 1:0 cbq bandwidth

Hey all, I had asked a question a little while ago about CPU usage being outrageous while using tc and a cbq qdisc. Ed was very kind and offered a few suggestions. One of these was to look at hashing. So after pounding away at it for about a week, I have a general understanding of how it works and have tried to implement it. Unfortunately, and quite obviously since I''m posting here, it

When I tried executing it I got this error. tc qdisc add dev eth0 root handle 1:0 cbq bandwidth 100Mbit avpkt 1000 mpu 64 RTNETLINK answers: Invalid argument Is there something I''m missing here...

OK, finally I have made cbq run ! now I would like to know if it is posible to limit a range of IP to a speed. something like this : from 192.168.1.1 to 192.168.1.21 limit to 128K I don''t whant to limit each IP to 128K, what I would like to do is limit all 20 IP to have a max of 128K. Is it posible?

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

hello, i have a 5500 iPaq with familiar 0.8.2 on it and i don''t know how to install a traffic shaper tool on it. I installed iproute2 package i found on familiar site and for that i have the tc and ip commands, but when trying to add a qdisc, as a dummy example, i get the next answer: > tc qdisc add dev wlan0 root cbq bandwidth 100Mbit avpkt 100 RTNETLINK answers: Invalid argument

Hi All , My first message and I have a little problem with my FC6 box trying to block emule traffic using layer7 .

Hi folks. For quite a while, I tried to use linux (cbq and htb) to control bandwidth in order to replace a cisco equipment used to play this role on our network. After trying here and there, with a bunch of different distros, different versions, different compilations, ... the closest I could get was as follows: (using htb.init and cbq.init) Desired BW ==> Achieved BW 128k ==> 404.78

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,

Hi all, I''m having a hell of a time getting my IFB to work. I know I''ve done this before, so I''m missing something stupid. Can anybody tell me what it might be?

I''ve been following the HOWTO, and reading mailing list discussions about throttling bandwidth, and have had some success, but I just want to tie off some loose ends. Essentially what I am wanting to do is to keep our bandwidth usage below 1megabit, because if we go over we get charged for that traffic. I''ve used some of the examples from the HOWTO to limit our bandwidth, but I

Hello, I am using the following commands to "throttle" the bandwidth of the NIC at eth0 : tc qdisc del dev eth0 root tc qdisc add dev eth0 root handle 10: cbq bandwidth 100mbit avpkt 1000 tc qdisc add dev eth0 root handle 10: htb tc class add dev eth0 parent 10: classid 10:1 cbq bandwidth 100mbit rate 128kbit allot 1514 maxburst 20 avpkt 1000 bounded prio 3 tc class add

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?
