similar to: PRIO / CBQ / HTB queue drop algorithm

Hello everyone! I''m simply trying to put a PRIO inside an HTB (used to throttle). I''ve got interactive traffic on the network that I want to give priority (VoIP + Citrix + Video). I''ve used the filters in a CBQ script fine, but am having trouble adjusting them to this setup such that they properly assign the traffic. tc qdisc del root dev $e tc qdisc add dev $e

Hi, I''m work on traffic shaping and I would like to know if it''s possible to mix differents Queueing Disciplines ?? I would like to combine the proporties of a PRIO discipline with that of a CBQ discipline. I read some documentation and I found nothing about that, can you help me ? I think to try something like that : tc qdisc add dev $DEV root handle 1: cbq … tc class add dev

Hello, I''am successful using a linux (2.4.20) bridge and the cbq.init_v0.7 script for traffic shaping. But I can only use the queuing discipline tbf (LEAF=tbf). If I try use queuing discipline sfq or none then tc applies the rules but no shaping occurs. Is this problem a normal behavior when using bridging ? I tried to use htb.init (using patched tc binary). It accepts the rules but

Hi, I wanted to implement some QOS on my Linux Box with HTB, but after some time spend on the configuration and tests, I still don''t manage to have some correct results. Here are the details : -ROOT 2000 kbits -HIGHPRIO SUBCLASS 50 kbits prio 0 -SUBCLASS1 750 kbits prio 1 -SERVICE1 250 kbits prio 1

Hello Thilo, What did you find superior with CBQ-wondershaper over HTB-wondershaper? We have not been using wondershaper specifically but our simple tests so far seem to show that htb is much easier to configure for a given target shape (i.,e accurate) compared to CBQ.

Hello, I have HTB on IMQ device. My rate does not work as I configured. I configured 1920kbit/s and I can download only about 290kbit/s (while it should be the whole bandwidth). My script: /sbin/modprobe imq numdevs=1 /usr/local/sbin/tc qdisc del dev imq0 root 2> /dev/null > /dev/null /usr/local/sbin/tc qdisc del dev imq0 ingress 2> /dev/null > /dev/null /sbin/ifconfig imq0 down

Hello, I use HTB with linux-2.4.20-ac1 and iptables-1.2.7a (pathced for IMQ). I configured one HTB qdisc on an IMQ device. This qdisc has some classes (about 5) and all of the classes has qdisc pfifo. I sometimes got out from my linux (while I was working) and I found in logs: Dec 4 11:49:27 core kernel: HTB init, kernel part version 3.7 Dec 4 11:49:28 core kernel: HTB: quantum of class

Hi, I am looking working (!) qdisc that would guarantee preferential treatment to priority (ex voice traffic). It is supposed to work as LLQ (Cisco) which means it is PQ but with bandwidth limited for EF PHB traffic. I did lots of tests with CBQ and prio set to 1 for EF PHB and prio 2 for best effort. Although delay does not look like being guaranteed at all for priority traffic. Eventually I

Hi, I have done this setup to give the machine 192.168.1.4 (masqueraded over dialup) the highest priority: #! /bin/bash WHAT="add" iptables -A PREROUTING -i eth0 -s 192.168.1.1 -t mangle -j MARK --set-mark 1 iptables -A PREROUTING -i eth0 -s 192.168.1.4 -t mangle -j MARK --set-mark 4 tc qdisc $WHAT dev ppp0 root handle 1: prio bands 3 priomap 0 1 2 tc qdisc $WHAT dev ppp0 parent 1:1

Ok, this has been kicking my @$$ for weeks. I'm trying to get some kind of bandwidth shaping working on my server. I need to throttle ftp down so as not to suck up all the available bandwidth. I had cbq working on the old server (an ancient RH 6.2 box) so I figured I'd just move the config over and get cbq.init from sf.net and it should work. Unfortunately it doesn't. At least

Hello ppl, I''m playing with the pfifo scheduler, its simple, and i cannot understand what''s wrong. So, i have test machine, with one interface eth0, and i want to send no more than 3 packets/sec out of that interface, so i do: tc qdisc add dev eth0 root pfifo limit 3 And i get pfifo scheduler on eth0 with limit of 3, but it sends as many packets per second as it wants, without

Help me  ... I try use the tc filter, but seems he doesn''t work, I already reconfigured my kernel ( 2.4.32 ) with all options related a QOS enabled ( like modules ) and nothing happens. I get the tc tool from HTB source package, well  this is my set : eth0 is my internal NIC. tc qdisc add dev eth0 root handle 1: htb default 12 tc class add dev eth0 parent 1: classid 1:1 htb rate

hello folks, this is my first post to that list. so I hope I am not completely OT here :-) reading the (excellent!) lartc and then writing my own qos-script I have still some open questions which I will try to formulate now: - "Now we can optionally attach queuing disciplines to the leaf classes. If none is specified the default is pfifo." - I can''t find info about Pfifo.

Hi there. Currently, our network design has two ISP lines and 3 subnets for LAN. Below are some details :- eth0 - isp1 eth1 - isp2 eth2 - subnet1 eth3 - subnet2 eth4 - subnet3 What i wanted to do is to assign incoming port 80 to our local squid server running on the firewall itself and assigned it to eth0(ISP1). I think it shouldnt be a problem as /etc/shorewall/rules provides a sample of the

Hello, I have problems setting up HTB. This is my setup : NET 1024/256 ADSL || eth1 Linux Firewall eth0 || LAN 10.a.a.a I want to GUARANTEE for an IP (10.x.y.z) a 800kbit bandwidth for HTTP download. But When 10.x.y.z does no HTTP download, other trafic must get the whole bandwidth, of course. The script I use (see below) is quite the same as presented at (the greeeeat page) :

Hello. I''m running linux box with Slackware 9.1 and compiled kernel 2.4.31 with "yes" to VLANs and "yes" to all QoS. On this box i have more ethernet interfaces: eth0 eth1 eth2 and so as more vlan interfaces: eth0.100 eth1.3 eth1.4 This is entrace(uplink) router to our whole network and my goal is to shape users on this machine. I want for this purpose use HTB so

Hi list, playing around with HTB showed that it may introduces pretty much latency for our setup. Docum.org says the following: "The default qdisc added to a htb class is pfifo_fast qdisc. The size of the qdisc is the device queue length and this is 100 packets for an ethernet device. So if you want to have a shorter queue, you have to add a shorter qdisc to the htb qdisc." Can
