Hi i have configured my server with cbq and gred. The problem is that the cbq doesnt drop packets. The cbq is configured at a rate of 500Kbit "qdisc cbq 4: rate 500000bit (bounded,isolated) prio no-transmit Sent 100103048 bytes 73933 pkts (dropped 0, overlimits 0) borrowed 0 overactions 0 avgidle 24000 undertime 0 " The traffic that being generated is more than 5Mbit with the

Dear all, I''m making a script to implement DiffServ policies with HTB. Here it is : if test $1 = "help" -o $1 = "h" -o $# != 5 then echo "usage: ds.sh <DEVICE> <DS_RATE> <EF_RATE> <AF_RATE> <BE_RATE>" exit fi DEV=$1 DS_RATE=$2 EF_RATE=$3 AF_RATE=$4 BE_RATE=$5 sync tc qdisc del root dev $DEV tc qdisc add dev $DEV root handle

I thought I had this all worked out, but it seems not. The following tc configuration: tc qdisc del dev ppp0 root 2> /dev/null > /dev/null tc qdisc add dev ppp0 root handle 1: tbf rate 120kbit burst 1200 limit 1 tc qdisc add dev ppp0 parent 1:1 handle 2: prio bands 3 tc qdisc add dev ppp0 parent 2:1 handle 10: sfq perturb 20 tc qdisc add dev ppp0 parent 2:2 handle 20: sfq perturb 20 tc

Hello, I have eth0 - internet eth1..4 - local networks on eth0 i do $IPTABLES -A POSTROUTING -t nat -o eth0 -j MASQUERADE I want to balance out/in load for eth1..4 and localhost (mainly squid). Nat makes impossible to do it on eth0, so I installed IMQ. I need to get to on imq0 unnnated in/out traffic that I could make priorities for protocols and networks. Do somthing like this: prate=1Mbit

Hi folks, I`ve a problem to use HTB and SFQ. The first script, below, to show a simple configuration, does work fine...!!! But, in the second example, does not work, becouse i put more code to clasify the traffic by protocol, http and ftp in this case. Somebody can tell me the errors? Thx, in advance.- NOTICE: IMQ device is to asociate with ETH1 my external iface. SCRIPT que funciona:

Hi, I''m using the application_helper.rb file to create some useful functions for generating links by name. I understand that functions defined in this file are available to all views, but what about constants defined in that module? Is there a best practice approach for doing this other than accessing each constant via ApplicationHelper::FOO? Stu

I''m a new comer. I have problems using tc+htb. I run the following commands, and expect outgoing ssh flow goes into 1:11. But actually it goes into default 12. What''s wrong? tc qdisc add dev eth0 root handle 1: htb default 12 tc class add dev eth0 parent 1: classid 1:1 htb rate 1000kbit ceil 2000kbit prio 1 tc class add dev eth0 parent 1:1 classid 1:11 htb rate 100kbit ceil

Hi, I would like to know how to specify the token rate when a tbf qdic is created using tc tool.. Will it be a default value when tbf qdisc is created? This could be a silly question.... im quite new to all these stuff.. but im really interested.. any help will be most appreciated... thanks in advance, sanjeev -- ______________________________________________ Check out the latest SMS

I presently use TBF with this syntax: tc qdisc add dev eth0 parent 1:100 tbf buffer=15000/8 LIMIT=30000 MTU=1500 parent class is a cbq with rate=128Kbit when I want to add PEAK, I get always RTNETLINK error: Invalid argument. Maybe be I don''t understand this parameter. What I know about it, it''s that it can control short-term burst traffic, and it''s what I need to do.

I''m trying to fill a token bucket with enough tokens to burst several gigs of data. However, it doesn''t seem to get any higher than ~3.9GB: >tc qdisc add dev eth0 root tbf rate 1440kbit latency 50ms \ burst 16000000000 >tc qdisc show dev eth0 qdisc tbf 800b: rate 1440Kbit burst 3908420240b lat 2197.8s A smaller attempt of ~1.6 gigs works just fine: >tc qdisc

Hi Everyone, This is a simple question but I don''t understand why the below tbf is not working as expected by throttling traffic to 5kbps If I throttle a PC''s traffic using the below when traffic exceeds 5kbps packets start getting dropped (as they should) but all traffic gets dropped. not just the bit over 5kbps. TC="tc add dev ppp0" $TC parent 8001:2 handle 2:

I am using tbf to do rate limitation. i set the rate, burst and latency parameters for tbf. but when i start passing data i notice that there is an initial burst and then the rate goes down to the configured level. is this because tbf starts with a full bucket? thanks. __________________________________________________ Do You Yahoo!?

Dear friends, thanks for the last advices about TBF. After reading the tbf.pdf document I got a better insight of the problems I had trying to limit the bandwith on my testbed with a high resolution. The question I have now is: Would I get an immediatly better resolution result if I change the #define HZ to 1000 for my Linux box? I have a Pentium Celeron 700 MHz, and I would like to see the tbf

Hello, I have one Q. What is better when using as leaf in one leaf with several hosts (like subnet) to splice traffic equaly to user number? Like 2 users = 256/2, 3 = 256/3 and so on. WRR was pretty good for this job, but it''s only for 2.4.21 kernels and mine''s 2.4.22. So what is better: SFQ or TBF? -- Artūras Šlajus _______________________________________________

I''m using tc from iproute-2.6.15 with a 2.6.12 kernel. I was testing the effects of the burst parameter in a tbf qdisc. Basically, I was testing this statement from the tc-tbf(8) manpage: "If your buffer is too small, packets may be dropped because more tokens arrive per timer tick than fit in your bucket. The minimum buffer size can be calculated by dividing the rate by HZ."

Hi everybody, it is my first message here. I tried to browse throughout older posts but I found no immediate answer. I need to change rate of a tbf queue while ip packets are already enqueued by it. If I go: tc qdisc replace|change|link dev eth0 root tbf rate 180kbit burst 1540 limit 15400 as results all enqueued packets seems to disappear. I can see that from a: tc -s qdisc ls dev eth0

Hi all! I just started to experiment with bandwidth management using tbf. I have the folowing problems with token understanding: 1) What unit is token? Is "1 token = 1 byte" ? If this is so, then with rate=0.5mbit and HZ=100 the bucket gets filled with 0,64kb (655 tokens) every 10ms? 2) How much tokens are used for one packet (1500)? 3) And token unrelated question. Does
