I hope you are understanding that I do not question your knowledge. I'm just not fully persuaded of this yet, so I'd like to discuss it a bit more. You are right to question me :-) - I was thinking a bit too much about my setup (At least I know that works). I use IMQ on ppp so I can shape traffic headed for local processes as well as forwarded. If you don't need to do this then you don't need to do it in prerouting anyway. I am guessing that calling IMQ from forward uses postrouting which is OK for your needs. I know from a test I did in prerouting that IMQ doesn't respect where in a table it gets called from. You could test by seeing if you can shape locally generated traffic marked in output I suppose. Wherever it hooks you need to set a rate less than link speed and if you use an old kernel, patch HTB. I said shaping from the wrong end of the bottleneck is a kludge because if I shape from the fat end then I control exactly what happens - I can arrange for my latency never to be increased by more than the time it takes for a packet my MTU long to be sent at my bitrate. As long as I tweak for link overheads I can use nearly 100% bandwidth. Incoming traffic from my ISP has already been through a 600ms fifo - it's never going to arrive at more than my link speed, so I need to set the ceils/rate totals to less than link speed - how much less will determine how fast the queue fills. The behavior of various types of queues is probably not the same as if they were at the other end of the bottleneck. There are also factors out of my control - TCP can get bursty when acks get buffered elsewhere. There may be packets in long buffers (mainly P2P) headed for me which are unstoppable, and my queue may not have any packets from active connections at any given time. The queue also reacts too late when the bandwidth changes - A new connection will be in TCP slowstart, which quite quickly will increase rate causing a temporary filling of ISP buffer - which hurts latency. It doesn't fill enough to cause drops, though, so as far as bandwidth allocation goes it's OK. My queues also drop a bit too much when this happens - causing TCP to resync which can be bursty. Andy.

Still problems :( I upgraded to kernel 2.6.9 now, configured IMQ to hook itself up after NAT, called it from prerouting, used u32 (matching works), set the root class to a rate of 800kBit (which is 200 less than my link speed) - and the behavior gets even worse :( Unfortunately, I cannot shape on the outgoing interfaces either, because there are two.

I really don't know what to do now... I haven't dug deep into CBQ yet - should I try it? Hmm - this should work. I just cobbled together a test - It's not very elegant because it's based on a slightly different setup, but it works for me. I use default as my local traffic has a dynamic IP - you don't need to . Note the U32 filters are attached to 1:0 if I attached them to 1:1 than I would need a rule to send traffic to 1:1. I wouldn't trust the output of apps for bandwidth tests - their averaging can be confusing - also if it weren't just a test I would add queues to the classes. Saying that I did notice that HTB was dropping - maybe the default queue length is shorter now?

Re: [LARTC] HTB problem...
Dnia poniedziaek 06 wrzesie 2004 23:56, Cow napisa: Hi folks. Let's say I would like to make some bandwidth control on my network using HTB. I have 2 clients: [...] I think a script as i described, could be very complex to write, therefore i ask, whoever is here, for help. Thank you all in advance. Hello all, my first post here, maybe even I will help someone;) I assume that you want somethink like: data from server to LAN (PC1,PC2) unshaped (full 100mbit) data from Internet to LAN shaped Then all you need to do is make classes with source 192.168.0.1 and destination 192.168.0.2(3) and 100mbit rate and then make classes with destination 192.168.0.2(3) with download rate. I believe that you understand what I am thinkig of. Or you can use iptables and mark traffic going from server to LAN, and other mark for traffic in FORWARD chain. (iptables -t mangle -A FORWARD -j MARK --set-mark SOME_MARK) When using iptables you will be able to shape upload speed, just mark traffic in forward going from PC1/2 with output interface eth2 (-o eth2) - it will be hosts upload. I won't write you full script, make it yourself, visit LARTC and firstly try htb.init for simple class creation.

It solves the 100Mbit LAN vs internet traffic by using a class setup which looks like [2], which reminds me that I did a modification to wondershaper once [3] that does the same. I think this modification was reported to work, however I haven't tested it nor do I support it. Maybe it serves as an example... I'm using a fat HTB class which knows the true interface bandwidth (100MBit isn't actually right, you should measure what rates you really get). Then there's a child class for the internet traffic and one for the actual LAN traffic. If HTB works correctly, this way you get full speed for LAN-only transfers, without letting them interfere with the internet traffic. The script [1] is the one I'm (more or less) actively working on; it doesn't support custom rates per user yet, but that's something that'll be added for sure in one of the next releases.

Re: [LARTC] HTB problem
Hello, I'm having some problems using HTB to prioritize traffic on my linux router. The main problem is as follows: I have a 6Mbits channel on the metropolitan network and a 64kbps link for the sites outside my country. These 64kbps are dynamically allocated by my ISP so I usually get something like 128kbps , sometimes 512kbps and even 1 Mbit; it varies all the time. Because of this I don't know how to automatically adjust my HTB script depending on the total bandwidth available on the external link (without specifying the maximum to 64kbps thus limitting every connection even if my ISP grants me more than this bandwidth). Anyone got any ideas ? You cannot have a variable bandwidth with htb.

Re: [LARTC] htb problem
do you have two nics? the 2megas internet is eth0 right? so you are tc'ing packets
going out of interface eth0.
paquets are comming from eth1 for example?
in such case you coutlf -t mangle -I PREROUTING -i eth1 -j MARK --set-mark {1|2|4|}
??
so packets going from internal (eth1) going out (eth0) are previusly marked.
im pretty sure about this.
hope it helps, good luck.

I have some more info on www.docum.org on the faq page. I read the manual of HTB and it says: 'Normaly you don't need to specify quantums manualy as HTB chooses precomputed values. It computes classe's quantum (when you add or change it) as its rate divided by r2q global parameter. Its default value is 10 and because typical MTU is 1500 the default is good for rates from 15 kBps (120 kbit). For smaller minimal rates specify r2q 1 when creating qdisc - it is good from 12 kbit which should be enough' So, is 'r2q 3' enough for 32kbit/s 'r2q 6' enough for 64kbit/s and 'r2q 10' (default) enough for 128kbit/s+?

Using only one thread, a single download can reach about 60% of the allocated bandwidth. Quantum is used if 2 or more classes with the same parent are fighting for bandwidth. First, they are allowed to get the rate you gave them. For the remaining bandwidth, quantum is used. Each class may send quantum bytes. You have to make sure quantum MTU (typical 1500 bytes for ethernet). What if you use no sfq qdiscs? Stef I have tried with pfifo queues and it's the same. I made many tests changing quantum, queueing for leaf but in no case I could reach the allocated bandwidth with a single download thread. The same limit set on cisco router with traffic-shape, worked fine. Could there be a problem when there are many qdiscs ? Are there many calculations to be done, so the packets get delayed and the TCP transfer rate is lowered.

Re: [LARTC] HTB problem (yet another one?)
endeavour:~# tc qdisc add dev imq0 root handle 1 htb ttt
What is ttt?
Usage: ... qdisc add ... htb [default N] [r2q N]
default number of class to which unclassified packets are sent {1}
and so on
Why do you have that ttt option? If you remove ttt from the command, does
it work?
-
And the PROBLEM:
When i try to add qdisc to the imq device.. a get:
endeavour:~# tc qdisc add dev imq0 root handle 1 htb default 20 r2q 10
RTNETLINK answers: Invalid argument
-
BTW: Adding CBQ qdisc to imq0 works fine... Any suggestions ?
What if you add a htb qdisc with no options ?
tc qdisc add dev imq0 root handle 1 htb
