Hi to all, i''m following this guide (http://www.opalsoft.net/qos/DS-28.htm), is very detailed, but i''m a bit confused about queuing disciplinse of leaf classes. In this guide the author uses PFIFO (see the scheme that i attached at message) in this way: # tc class add dev eth0 parent 1:21 handle 210: pfifo lmit 10 # tc class add dev eth0 paren...

Hi! I am learning tcng without having experiance of tc and I am trying to build something that shall schedule traffic dependent on the value in the IPv4 packets ip_ttl field. I have read the tcng reference manual and cannot find information about forwarding. Is it possible to farward packets from ingress to egress without sending them upwards in layers?

Hello all, Please could someone help me with this, I have been trying for days to get this to work. I would like to have BE, AF & EF classes with HTB qdisc. I can''t find any scripts online where this has been done. If I enable this filter: #tc filter add dev eth0 parent 2:0 protocol ip prio 1 \ #tcindex mask 0xf0 shift 4 pass_on then BE & AF classification seems to be fine but

Hi guys Finally , after reading a lot of docs from larc/opalsoft/etc, I decided to start learning some QoS First of all I''m trying to shape only download from a iptables+squid+qos machine for 4 machines at LAN ( eth0) Can anyone help me , cause it is not working properly.. ----------------------------------------------------------------- #!/bin/bash...

I ''ve been trynig for a long time now to make HTB and GRED to work togethen. The problem beeing that GRED doesn''t use handles (instead it uses DP:1 DP:2 etc) i can not preperly filter traffic to them. Tomas Graf suggested to use the tc_index index of u32 classifier so dear Sant .. i am currently with the following scripts that works! But when i try to add an HTB before the

Hi, I''m trying to configure IMQ to work on the same machine with frottle (http://frottle.sourceforge.net). The problem is both feed themselves packets through netfilter queueing mechanism, but currently there can only be one netfilter queue per protocol family. To explain why I need IMQ in the first place I have to explain what frottle does. It is a deamon that tweaks the behaviour of a

Hello list, I guess I am jumping in here at the deep end... I have had a look at the lartc web pages, found the wondershaper script, read through as much of the HOWTO as possible without my brain exploding, and I feel that I get the concepts kinda OK. The thing that I am having trouble with are the tc "filtertype specific parameters". I''ve read a great message on the archives

Has anyone ever managed to use GRED and HTB ? Been googling all over the net for hours and did not manage to find any proper implementation. In my case all AF traffic goes into VQ 3 In opalsoft afhtb example traffic goes into VQ 1 & 2 any script will do just fine for me Thanks in advance , Antonio _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

Hi fellow traffic-shapers, I am implementing a Diffserv CORE router using Linux kernel 2.4.18. I used this excellent website (http://www.opalsoft.net/qos/DS-38.htm) using AFHTB as a starting basis for my EGRESS diffserv implementation - and all works great so far!!! But my project has an additional requirement. There are services running locally on the router which are sending/receiving IP traffic also. These services are leaving the DS...

Anybody knows about one bandwidth meter to use in Bering. This is a script i built, it''s works wel, but it''s not very nice!!! =P #!/bin/bash # Bandwidth Monitor device=eth0 bytes=`grep $device /proc/net/dev | cut -f 2 -d : | cut -d '' '' -f 2` kbytes=`expr $bytes / 1024` actual=$kbytes i=1 x=0 total=0 while [ $i -le 2 ] do x=`expr $x + 1`

Hello all, Can anyone recommend a good book which thoroughly explains QoS from a Linux perspective? Something with TC examples & the like. I''ve looked at the following: http://www.amazon.com/gp/product/1580533418/qid=1148368189/sr=1-2/ref=sr_1_2/102-2819973-6353768?s=books&v=glance&n=283155 Engineering Internet QoS. Thanks.

Hi all, Here is something that i still haven''t understood. When installing PRIO, it creates 3 "classes" with priority level according to the TOS. That command line : # tc qdisc add dev eth0 root handle 1: prio give that result : # tc qd sh qdisc prio 1: dev eth0 bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1 How should i read that priomap, what does it mean and how to

Hi, I am working on linux 2.6.16.I tried to prioritize traffic using prio module but its not working well.It always maps to same class irrespective of ToS.Is it possible to fix it using filters?Anybody fixed this problem? -- Regards Archana Rajagopal _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc

Hi gang, I have an application that is sending streaming media to a server. The encoder computer sends an average of 200kbit stream; but for short, 1 second bursts, can hit 400-500kbits. After it does one of these bursts, it reduces its output for another second or two, so that it maintains its average of 200kbits. The problem is that it is sending UDP packets into a DSL link that has a fixed

i am trying to do some traffic classification using the PRIO qdisc and i am having a few problems. I have a root htb class: tc qdisc add dev imq0 root handle 1: htb default 255 r2q 1 tc class add dev imq0 parent 1: classid 1:1 htb rate 768kbit and a child PRIO tc class add dev imq0 parent 1:1 classid 1:99 htb rate 96kbit ceil 600kbit prio 0 tc qdisc add dev imq0 parent 1:99 prio tc filter
