Re: [LARTC] 2.6.14 - HTB/SFQ QoS broken?
When configuring this, I thought the priorities would make that work.They even DID that because it was working once. The whole point why I configured it like that:I (and everyone else probably) want the scheduler to be like:"Give all bandwidth to eMule if nothing else is running.If miranda filetransfer is running give all bandwidth to it UNLESS Apache is running, then Apache should receive all bandwidth."This is not possible if the bandwidth reservations dont overlap, is it?Or can anyone tell me a different qdisc / solution which allows this? It's undefined what happens when you overallocate, and is certainly not required to do what you want. 'rate' is guarenteed rate, 'ceil' is maximum bandwidth useable through borrowing, and 'prio' is priority this class gets when borrowing bandwidth. You should give emule next to nothing for guarenteed, but with a ceil either the max bandwidth or very close. It is then guarenteed little, but will borrow up to its ceil. Then guarentee apache most, with some left for default. the prio will mean apache has first access to any borrowable bandwidth, then default, then emule. I would use something like this: IFUP=48$addc $cMAIN classid $cEMULE htb rate 4kbps ceil ${IFUP}kbps $q1 prio 5$addc $cMAIN classid $cMIRANDA htb rate 30kbps ceil ${IFUP}kbps $q2 prio 2$addc $cMAIN classid $cDEFAULT htb rate $[$IFUP - 30 - 4]kbps burst 6k $q2 prio 1 I'm using something fairly similar:#roottc qdisc add dev $DEV root handle 1: htb default 122#main rate limitertc class add dev $DEV parent 1:0 classid 1:1 htb burst 30k rate ${UPLINK}kbit ceil ${UPLINK}kbit #high priority low bandwidth traffic (75% bandwidth guarentee)tc class add dev $DEV parent 1:1 classid 1:11 htb burst 30k prio 0 rate $[($UPLINK - 4) * 3 / 4]kbit ceil ${UPLINK}kbit cburst 4k#most traffic (25% bandwidth guarentee) tc class add dev $DEV parent 1:1 classid 1:12 htb burst 30k prio 1 rate $[($UPLINK - 4) / 4]kbit ceil $[$UPLINK - 16]kbit#no priority traffic (4kbit guarentee, ceil torrentpercent)tc class add dev $DEV parent 1:1 classid 1:13 htb prio 7 rate 4kbit ceil $[($UPLINK - 4) * $torrentpercent / 100]kbit #further split most traffic into game, and non-game#gamestc class add dev $DEV parent 1:12 classid 1:121 htb burst 30k prio 1 rate $[(($UPLINK - 4) / 4) - 4]kbit ceil $[$UPLINK - 4]kbit#non-gamestc class add dev $DEV parent 1:12 classid 1:122 htb burst 15k prio 6 rate 4kbit ceil $[$UPLINK - 4]kbit #tc qdisc add dev $DEV parent 1:11 handle 11: sfq perturb 10tc qdisc add dev $DEV parent 1:121 handle 121: sfq perturb 10tc qdisc add dev $DEV parent 1:122 handle 122: sfq perturb 10tc qdisc add dev $DEV parent 1:13 handle 13: sfq perturb 10 Few things i remember tweaking is increasing the burst for the higher priority classes.

Hello! I'm not sure if I fully understand Your problem but tc is able to change specified class without destroying all classes and disciplines on network interface. I use perl and php webpanel for setting up speed limits for my clients. Loading all tc rules for all interfaces (and imqs) after every single change is very slow, but I am able to change the one I need after changing settings of one client with `tc class change`, after which I put all the stuff that normally goes with `tc class add`. -- | pozdrawiam / greetings | powered by Trustix, Gentoo and FreeBSD | | Kajetan Staszkiewicz | JID: [EMAIL PROTECTED] | |Vegeta | IMQ devnames: http://tuxpowered.net| `^' ___ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc

The way I see it, the email is correct. A class that has the same rate and ceil will never borrow, simply because it does not have to. As for lending, that will happen only if one of it siblings wants to borrow bandwidth. As for children classes, they are restricted by their parent. They cannot take bandwidth from outsiders, unless their parent borrows it for them. That does not help the original poster in any way, however.

I cap P2P to only 95% of the upload (used to be 85%) and give it a guarenteed rate of only 4kbit. It will use its full 95%, but as soon as I use something else, i'll use 100% of the line and as much as possible for the non P2P traffic. http://webpages.charter.net/falconx/eth1-50-tc-cumulative.pngThis image shows how this ends up working in reality for me, orange is P2P, blue is default, and red is priority. I'm not sure on the exact command to use for an imq, but possibly something like `tc -s class show dev imq0`?

[LARTC] 2.6.14 - HTB/SFQ QoS broken?
Hello, First of all, I already contacted Martin Devera, the developer of HTB, and he told me to search for help on this mailinglist, thus I am describing my problems here now... I am kind of seriously annoyed by QoS as I have been trying for over 3 years to get it working properly - first I did not understand how it works, then it seemed not to work, then it was working perfectly for half a year, or at least it seemed to do so, and now it seems to be broken. I have read so many QoS HOWTOs and I'm quite sure that I have understood the default approach for upstream bandwidth limiting/prioritizing - it is always the same in these HOWTOs: A root HTB qdisc is added to the network interface. This HTB receives a child class HTB to allow bandwidth sharing between the different classes (for example peer2peer, ftp, etc.). The actual HTB leaf classes are then attached to this class. These leaf classes finally each receive a SFQ which serves the purpose of fair queueing AND giving a package queue to HTB so that it does not have to drop packets. Here is my implementation of it: IFUP=48kbps tc qdisc add ppp0 root handle 1:0 htb default 20 r2q 4 $addclass 1:0 classid $cMAIN htb rate $IFUP mtu 1492 $addclass parent $cMAIN classid $cEMULEhtb rate 8kbps ceil $IFUP prio 4 $addclass parent $cMAIN classid $cAPACHE htb rate 32kbps ceil $IFUP prio 2 $addclass parent $cMAIN classid $cDEFAULT htb rate $IFUP burst 6k prio 1 $addqdisc parent $cEMULE handle 10: sfq perturb 10 $addqdisc parent $cAPACHE handle 20: sfq perturb 10 $addqdisc parent $cDEFAULT handle 30: sfq perturb 10 As you can see, eMule can use all bandwidth as long as nobody is requesting something from the webserver. If somebody is downloading from the server, he should receive 32kbps and eMule should be slowed down. Normal traffic (browser requests, multiplayer gaming, etc.) should receive all bandwidth if necessary, and have the highest priority, thus allowing good ping times. Well, I have written that script about half a year ago, and back then it was working well, and I even installed a linux router for someone and there it is still working. BUT now I have checked the speed of my webserver, and when eMule is running it is only at 4 kb/s instead of 32 kb/s. AND I have found the reason for this: If I remove the SFQs, scheduling seems to work - at least at the "bad precision" of HTB: Apache receives over 20 kb/s and eMule is limited to 12 kb/s instead of 8. Now what exactly is the reason for this? I thought it was absolutely normal to have these SFQ queues? Removing them is no solution because HTB starts dropping packets then. Martin Devera told me that it is wrong that the sum of the child-HTB's rates is larger than my interface speed. Well, I reconfigured to have the sum equal the available bandwidth and even then QoS did not work. And finally the most weird fact: On the other box where I have installed my QoS script it is still working properly. When Apache is uploading, eMule is slowed down to 4kb/s. So I copied the script back to my box and there it does not work!? I did not change the configuration of my linux router very much, I only usually update all packages with aptitude and install the latest kernel myself.

(Now I know I did it wrong) So, if you don't want it to borrow like you said, the solution would be to set the ceil of the P2P class to 100kbit as well. The other classes will still be able to borrow from it if the P2P class is not using it's bandwidth. Are you sure? In my previous post I was refering to this example http://mailman.ds9a.nl/pipermail/lartc/2002q2/003958.html which says this class won't be able to exchange any bandwidth at all.

I simply block p2p traffic for some time and see that bandwidth usage (according to iptraf) falls down to ~20% of total link's "capacity" + classes that are supposed to send p2p traffic send nothing. (I also get feedback that indeed p2p apps aren't working) After allowing p2p through, bandwidth usage jumps to ~100% of the total available bandwidth. Are you using thee CONNTRACK module? It's simple to block P2P without CONNTRACK but if you want to shape it, you need it. Otherwise you'll only be marking the first packets for p2p connections, and not the rest. I am aware of that, but didn't you mean CONNMARK target (module)? W ___ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc

Your P2P class has 100kbit rate with a 5600kbit ceil, but you say you don't want it to borrow bandwidth from other classes. However, to go over the 100kbit rate, it _has_ to borrow. So, if you don't want it to borrow like you said, the solution would be to set the ceil of the P2P class to 100kbit as well. The other classes will still be able to borrow from it if the P2P class is not using it's bandwidth. If this does somehow not seem to be what you want, please restate your requirements. :-) Kind regards, Andreas Klauer ___ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
[LARTC] class exceeds its ceil
Hi, I have a setup like this: class 1:1 rate 7600kbit (on a imq device) | |\class 1:10 rate 100kbit ceil 5600kbit prio 7 (here goes p2p traffic) \class 1:12 rate 7500kbit ceil 7600kbit | |\class 1:121 rate 3100 ceil 7500kbit prio 0 |\class 1:122 rate 2200 ceil 7500kbit prio 2 \class 1:123 rate 2200 ceil 7500kbit prio 3 (default) My problem is: the 1:10 class consumes the whole bandwidth. This is caused by a massive p2p traffic. I've read similar posts on this list, and I can't use the solution proposed by Stef Coene here: http://mailman.ds9a.nl/pipermail/lartc/2002q2/003958.html. I match p2p packets with both ipp2p and layer7 filters and mark them with iptables MARK. I can easily block p2p traffic, but when I allow it - it exceeds its ceil and reaches the rate of my internet link, which is unacceptable. I need to allow other classes to borrow bandwidth from a p2p class, but I do not want to allow a p2p class to borrow bandwidth from other classes. Is there a way to achieve it ? maybe I should redesign something in the above diagram. W ___ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
