similar to: internet traffic from tbf

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

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

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

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

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

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 having a problem here I'm not sure how to solve, so I hope someone else have done the same (and succeeded :) I have an old smb server ('tux') which is ancient (both in software and hardware) and can't handle the load. This machine is running version 2.2.3a-14.1 (Debian GNU/Linux woody) with 'character set = ISO8859-1'. The new smb server ('bella') runs

I have the same problem, trying to cross-compile. I'm running Ubuntu Edgy, kernel 2.6.17-10-generic, on an IBM T60. I downloaded the Makefile from CRAN and ran make CrossCompileBuild with the following error messages (also ran each make one at the time and the problem occurs in make R): ../extra/pcre/libpcre.a(pcre_dfa_exec.o):pcre_dfa_exec.c:(.text+0x1703): undefined reference to

Hi, Can someone please help me in finding when/where memory_static_max / memory_static_min variables are initialized in the code? Thanks in advance.

Hi, Having issues getting a replace command working correctly. The error reported is "RTNETLINK answers: Invalid argument" which isn''t descriptive or helpful. The command i''m running is: tc qdisc replace dev ppp0 parent 8001:D handle D: tbf rate 5Kbit burst 5kb latency 70ms The idea being to replace an sfq with handle D and hopefully limit a certain user in my

Hi, My branch office as got a 256Kbps b/w from their service provider at a very very high rate per Mb. They don''t require 256Kbps at all but the ISP does not offer anything low. Can we restrict the bandwith to say 64Kbps nothing fancy? How do I go about it? With warm regards, -Payal

Hi   I am running a web server in one of my xen guests. Using ab as a load generating tool i have collected some throughput data for different file sizes like 5KB, 10KB and 100KB. One thing that i have noticed strange here is throughput drops down in a virtual http server, it happends in case of 5KB and 10KB files. Also it takes longer to run tests in virtual environment.

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
