Hi,All I am using iproute2 to manage bandwith for ADSL router.High,medium,low priority are needed for different protocol port on the ADSL's upstream side,as following: LAN --- |ADSL Router|------WAN When there aren't traffic on the specific priority, its bandwidth should be borrowed by other priorities.But it doesn't work.Here is my script: /usr/sbin/tc qdisc del dev nas0 root

How to do ensure a class not lended and not borrowed each other. I do cburst burst 0b ,but ctokens tokens go to negative! --------------------------------- Do You Yahoo!?

We have several latency-sensitive "pipeline"-style programs that have a measurable performance degredation when run on CentOS 5.x versus CentOS 4.x. By "pipeline" program, I mean one that has multiple threads. The mutiple threads work on shared data. Between each thread, there is a queue. So thread A gets data, pushes into Qab, thread B pulls from Qab, does some processing,

Hi, If I have a DSL router with 300kpbs upload bandwith: Linux(eth0) ---(100Mbps)---> DSL ---(300kbps)---> INTERNET Which is the recomended value I must set in my QoS setup for the maximum outbound bandwith of my ethernet interface ? The max of 300kbps or something less like 290kbps ? Especify less than the maximum available bandwith is advisable to ensure that the QoS algoritms goes

hi,Stef: I read your burst test,I have some questions remain. A and B have immovability bandwith: If I bound bandwith to machine A and B,in order to it have 4Mbps,the other machine B have 6Mbps,(I have 10Mbps total). between them no permit bend from each other. whether burst cburst tokens ctokens value is zero. it''s right? --------------------------------- Do You Yahoo!?

Hello, I''m Alexandra Well, i have been working with cbq around 3 month ago without any problems, what i do is control the bandwith to 64Kbit for input and output and it works well. But now I don''t want control the Bandwith, i only need prioritize udp trafic over tcp trafic Can somebody to help me with my requirement? Thanks Alexandra

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, I live in a rural community where adsl and cable is not widely available. I correctly have an option of using adsl or cable at my location. Ten miles away my friends apartment building has no option of cable or adsl. I set-up a wireless link between my friends apartment building and my house. It works great for him and me and the adsl company doesn''t care because they

tc qdisc add dev eth0 root sfq perturb 10 I want to set perturb to 8 then i used this tc qdisc add dev eth0 root sfq perturb 8 system give me the following message RTNETLINK file exists I delete the rule by this :"tc qdisc del dev eth0 root sfq perturb 10" please tell me how can i delete the rule by another way and where is "RTNETLINK file"

I'm seeking a small IMAP server, and dovecat was recommended by those more savvy than me. (The sign on my monitor is "My programming language is solder..") so I'll be getting help to deploy this, but first... I've read through the wiki docs but still have questions, ones likely too obvious for most readers.... There will be <100 users, the platform will Debian, and I

how can I configure for shaping bandwith using cbq/htb without delay or latency?

Hello, I''d like to build a 4 class prio system based on mark (until now no problem), but with a limited bandwidth. I have configured my eth* to be 10mbit full duplex, and I''d like to limit the bandwidth to 1mbit. I managed to do it with a policy filter matching all the traffic, but I can redirect it into only one class, so all my prio classes are useless. I also tried to limit

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, Leo here''s the information: Having being bombarded for not providing a link, i guess its time. Actually wanted to see the response first, we would like interested parties we can communicate too in other to get updates on how the code is performing. Please if your interested or you know someone that is, send a mail to <alexander.clouter@connectfree.co.uk>,

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 Stef, Reffering to page < http://www.docum.org/stef.coene/qos/faq/cache/7.html > I found a para as follows, " CBQ is not always as accurate as it should be. See docum.org on the test page for some tests with bounded classes. The algorithm used by cbq is very "link sensitive". It calculates the link idle time and for that it needs the real link bandwidth, average

Hello there, Having made quite a lot of expensive mistakes i have finally clobbered together a script for the users on my network. Have a look at it and please suggest as to how can i limit bandwidth to each ip on this network to about 64Kbits.

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
