Hi all, I am having some fun with traffic shaping, and have run into an interesting situation. Here is South Africa, most internet links are heavily oversubscribed, which means that in most cases the local link is _not_ the bottleneck, and shaping on the local link does not help that much... Does anybody have some tips on shaping such links? How can you get interractive traffic if you

Hi all, I have the following problem. A Linux box configured as a bridge. One interface connects to the router via a crossover cable, the other connects to a switch via the cable that used to go to the router. Now I get the following: [root@localhost net]# ifconfig eth3 eth3 Link encap:Ethernet HWaddr 00:03:2D:07:61:5D UP BROADCAST MULTICAST MTU:1500 Metric:1 RX

Hi again, I was just looking around for ESFQ sources, and I see that the main site is down, and only has kernel 2.6.4 patches. Is ESFQ maintained? If so, where can I find patches for 2.6.10?

Hi all, Another requirement we have is that traffic entering the DS domain be classified then subsequently assigned a (different?) DSCP based upon its classification. For illustrative purposes only let''s say (for traffic entering the DS domain on dev eth0): - WWW traffic would be marked BE - traffic destined for 10.10.10.10 would be marked AF11 - VoIP traffic from 20.20.20.20 would

I wrote a Perl script to poll `tc` for traffic control statistics (just bytes presently) for leaf qdiscs. The information is fed to either RRDTool or Munin[2], depending on what parameter is passed to the script. If the option for a RRD database is used, graphs[3][4] are written to disk for each ten second polling interval. If invoked via Munin[2], it handles graphing and samples at five

OK - this is starting to get frustrating... Are there any known issues with 2.6.9 and traffic shaping? I am using 2.6.9 with geoip 20041115, and get odd oopses. The following script oopses my box: ----------------------------------------------------- #!/bin/sh -x IFOUT=''eth1'' IFIN=''eth0'' TC=''/sbin/tc''

Hello, I have finally managed to understand HFSC up to a level which allowed me to create a QoS script which maintains low VoIP latency while running stuff like eMule. Unfortunately, HFSC seems to have a severe bug. Why do I consider this as a bug defenitely? Well, my script runs without any errors, then QoS works perfectly for some hours, no error messages in kernel log. Then randomly the

Hi, I''m a complete newbie at this traffic shaping / QoS stuff so please excuse me if this is a silly question. I''ve searched and searched on Google and I just end up confusing myself even more, so I thought I''d post my question to this list and see whether someone can help me! Basically, I am running a Linux box as a NAT router on my home network (machine name marvin).

Hi, I''m looking for info about IFB devices and how I can use it to incomming traffic shapping. Has IFB any web about it? Do any body known where I can find more info about it? I found this: http://linux-net.osdl.org/index.php/IFB But I can''t stand fine how to use it to allow many ifb''s devices or how to use it with "tc actions". Any help? Thanks --

Hi, I am a newbie to LARTC and to this mailing-list. I have read through the Linux Advanced Routing & Traffic Control HOWTO many times, trying to understand Classful Queueing Disciplines (and in particular CBQ). I have some suggestions that I think will help to make the HOWTO more understandable. Suggestions ========= (1) In section 9.4 (Terminology) the definition for

Hi, Is there any tested good HTB script for traffic shaping available like as that of CBQ available at. http://freshmeat.net/projects/cbq.init I am n new bie and need to work on htb. -- Regards, M Arman _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc

Hi, I have a rather simple problem I have to solve, well I thought it would be simple, I''ve run into a problem. I think I must be missing something fundamental. I am trying to build a Linux router that simply throttles everything down to certain bandwidths. That is, no priority queuing ...etc, just slow all traffic down to the specified rates, which are 64,128,256,512 kbit. We want

Hi all, I''m having some problems setting up qdiscs on a bridge.The config looks a little like this: ifconfig ifb0 up # Bring up the IFB for this bridge. tc qdisc add dev eth2 ingress tc qdisc add dev eth3 ingress tc qdisc add dev ifb0 root handle 1:0 cbq bandwidth 100Mbit avpkt 1000 cell 8 # Raw qdiscs on each bridge port tc qdisc add dev eth2 root handle 1:0 cbq bandwidth

Hello everybody, I try to work with TC for a little while in my study and there still are a few questions that I can\''t find any answer anywhere. Firts about qdisc and classes: - What is exactly the difference between qdsic and class ? They are so \"intimately tied together\" that i\''m not sure not make the difference. Why can\''t we have a qdsic HTB with

Hi all ! I''m building a network appliance whose goals are to enhance Voip quality on 512/128k DSL links. But, i have a voice quality problem, and i think i''m doing something wrong, but i can''t find what. Please excuse my terrible english, i''m french. >From what i''ve read, tc is the tool i need. I read the documentations, readmes and lartc.org

Hi all, based on the information in the "Linux Advanced Routing & Traffic Control HOWTO", I was trying to set up traffic shaping on my firewall. While I found the HOWTO very useful, in the process I ran into some problems that I did not forsee: According to the HOWTO it seems that it should have worked, even after spending some time going through the sections looking for answers,

I think that there are no qdiscs that permit to drop the oldest frame of a queue when this queue is full, but I would like to be wrong: bfifo drops arriving frames when the max queue length is reached. red also drops arriving frames in a more elaborate fashion, with a drop probability that increases above a limit and becomes a drop certitude when the max queue length is reached. sfq drops

Hi, I''m trying to use prio qdisc with htb, however not the "usual" way (like for example FairNAT). Here is my idea: Root has HTB shaping traffic to link speed -> then goes PRIO queues -> each prio queue has HTB with sublasses for each user, should look like this: 1: htb qdisc | 1:1 htb class

[I sent this earlier but I guess the list is subscriber-only?] I just set up wondershaper, it has a simple filter on the downstream direction to limit the bandwidth usage: tc qdisc add dev $DEV handle ffff: ingress tc filter add dev $DEV parent ffff: protocol ip prio 50 u32 match ip src \ 0.0.0.0/0 police rate ${DOWNLINK}kbit burst 10k drop flowid :1 This is effective but is there any way to
