Hi have set the following tbf tc qdisc add dev eth0 root tbf rate 0.5mbit \ burst 5kb latency 70ms peakrate 1mbit \ minburst 1540 I want to add a filter so the ip traffic pass from it.. plz help me __________________________________ Yahoo!

Hi, Can you please explain to me the difference between rate and peakrate, in conjucture to TBF. IMHO, rate : controls the no. of pkts flowing through the pipe, and peakrate : controls the no. of tokens flowing through the bucket. A funtion(?) of peakrate and mtu is rate. If this is true, why do I need to specify both peakrate and rate? Regards, suraj. __________________________________ Do

Hi all, I''ve tried to look for this info in previous messages but had no luck. I''ve a 2.4.20 kernel on an Intel arch., all TC is configured and it seems to work. Anyway, I''ve had some troubles in configuring TBF via tc: 1. when I configure burst or minburst to be, say, 1500b, when I peek the configuration with "tc -s qdisc" the answer is that

I am using the script below to simulate a very low bandwidth connection. I found that I could turn the bandwidth knob down to about 4kbit, but below that I didn''t get any traffic through. I''ve had a look at this generally, but couldn''t find an answer. It doesn''t even seem like the first reply packet gets through. I have tried it with much bigger buffers,

I''m just-so-fresh to the list, so hello everyone. I''m having a realy hard time with setting up very simple bandwidth management. What I am trying to do is setup a 10Mbit interface to send at only 1920kbit to most of the network (to make sure it hardly ever tops 2mbit). I did succeed with the ingress traffic... With egress however, I get very odd results at different speeds. With

Hello, I am attempting to use the LARTC traffic control to simulate a radio link that has variable bandwidth and availability. The basic bandwidth could be as low as 500 bits/sec but will generally be about 4000 bits/sec. If the simulated radio link is unavailable (zero bandwidth) then packets should be queued until a link is re-established. i.e. Initial bandwidth is 5000bits/sec then to 0

Dear Community, sorry for the somewhat dumb question. Maybe someone has any pointer to how to setup the RED queue to mark pakets with ECN. In particular what are appropriate parameter settings for limit, min, max, etc. All my trials end up with either "RTNETLINK answers: Invalid argument", although the command line (at least for me) looks fine in regard to what is said on the

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, I am a completely newbie, and have been doing intense reading for the entire last week, and have the following novice question: In section 9.2.2.2. of LARTC HOWTO, the following sample configuration given: # tc qdisc add dev ppp0 root tbf rate 220kbit latency 50ms burst 1540 Why is the burst parameter value determined to be 1540? Thanks, Todd

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."

Hello Please give advice in selecting suitable QoS Solution for our device. It contains one WAN port and a LAN port(4 port switch). The WAN will be connected to an ADSL modem(so we don`t know the bandwidth in advance for the WAN and depends on the ADSL connection taken). We need to give highest priority to the Voice and control the WAN bandwidth to 2Mbps. I tried with the TBF by giving 500kbps

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

Quick question: How do I delete an ingress tbf? [root@atlas root]# tc qdisc qdisc tbf ffff: dev eth0 rate 50Kbit burst 2999b lat 1us [root@atlas root]# tc qdisc del dev eth0 ingress RTNETLINK answers: Invalid argument _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

Can I attach a SFQ qdisc after a TBF qdisc?

http://ds9a.nl/lartc/manpages I finished some more manpages, and improved others. New are tc-tbf.8, tc-sfq.8, tc-prio.8 and tc-red.8. Please check & use them. http://ds9a.nl/lartc/manpages -- http://www.PowerDNS.com Versatile DNS Software & Services Trilab The Technology People Netherlabs BV / Rent-a-Nerd.nl -

Probably this is an old question, but i''m not able to find nothing about... So, i''ve just started to play with tc to limit the transfer speed to my hdsl connection. I''m using the tbf and the command # tc qdisc add dev eth0 root tbf rate 10kbit latency 50ms burst 1000 Then i''ve tried to transfer a big (20 Mbyte) file onto my lan, using ftp and the client

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.

Hi i need some good documentation about htb and tbf implementation in Linux kernel 2.6 and only for Linux..thx a lot __________________________________ Do you Yahoo!? Yahoo! Personals - Better first dates. More second dates. http://personals.yahoo.com
