hi all At last i got sucess !.. but am confused y it didnt work earlier..the difference today was that i reinstalled RH7.2 & complied kernel 2.4.16(not 17).. rest was same..... & the bandwidth too is under control!.. is it normal for to get more than said bandwidth--i mean i restricted a network with 8Kbit(with same script as below) but still was able to get a download(ftp) of

Hi all I am conducting the experiments comparing IP router forwarding delay and MPLS LSR forwarding delay, it is obvious in theory MPLS in Core should be faster than IP, but for small netork (only have several core routers), result show it is not, this is why I want emulate a large IP routing table in one core router. can I do it and how ? right now I use static routing table (by using command :

I forward this to the list also, I attached SFQ leaf to parent class, and add QUANTUM value and PERTURB value. It worked! i tried 20hosts borrowing from the same parent, no problem. Each host get its own allocated bandwidth. Btw about last email sent to this list asking about QoS, i ve read LARTC document but i cant find the solution matches my case. Need help.. I have 100Kbit allocated to

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

Hello all, I have using htb for last 10-12 months to manage the bandwidth share. Until last month everything was ok, but now after a kernel upgrade (from 2.4.20 to 2.4.26 because a kernel bug that generate a oops) the Linux router is droping packets. It is weird because the "tc -s class ls dev eth1" (in the class I monitor) reports no packet drop, the "tc -s qdisc ls dev

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

Dear. folks I want to shaping FTP traffic. I can get following information from Stef Coene's Homepage, www.docom.org. "Ftp uses random ports, so matching the data traffic is not easy. However it can done if you use iptables to mark ftp-data packets and use that mark with the fw filter. For more info see http://home.regit.org/connmark.html. " General information about the conntrack

I have successfully implemented a QoS system using HTB on a 2Mb/s leased line and it works very well, but I would like to be able to graph the three pipes to see what they are doing, eg: using MRTG or similar. Has anyone any experience or examples of how to do this please? Thanks, Chris _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl

Hi! I have configured traffic shaping with htb and imq but when i am downloading the latency for example on the Bnet class is very high ..... example: 65 kb/s download best latency: 56ms lateny on bnet class while downloading: 400 350 250 350 400 100 300 200 80 200 300 250 ..... To get informations about latency i am marking ping packets with iptables. I want to play during other users

Hi, I''m subscribed to this mailing list for a long time. During that time, I enjoyed reading all posts and try to understand them :) LARTC started as a something I could use to impress my boss. After a while it became clear to me that my boss was not impressed ;(, but I kept following this list because it was fun. I also placed a lot documentation online on

I posted earlier when I noticed that htb was releasing packets in pairs, even though my burst/quantums were 1 pkt. To fix I set HTB_HYSTERESIS 0 in net/sched/sch_htb.c . This gives a noticable gain in upstream worst case latency, for me with 256kbit/s up I used to see +90 sometimes, now it''s +45. For the many who have 128 up it should limit them to +90 rather than +180. Andy.

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
