similar to: HTB shaping & borrowing info

Hi to all, i''m using htb.init for configuring my shaper. Now i want to know if it possible to show how htb.init make and use TC, anyone has tried it?

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 parent 1:22 handle 220: pfifo lmit 10 #

Hello list, i thank you for the precious info you gave me, they were really useful in my work. I need to work with TC on a virtual interface. Is it possible ? How ? There is any doc on this topic ? And foremost, is my idea of working with TC on a virtual interface viable ? I am wondering if to control the traffic which comes in on a specific inferface is better to use TC''s filter or

Andreas, Since I understand your ASCII art and comments, I would very much appreciate it if you would draw what you see and criticize the following. Hopefully I''ll better understand after that!

Hello, after spending several hours reading archives, I decided to write new post. I successfully set up packet classification, made some basic HTB setup, made some simple graphical representation from HTB statistics data... BUT, I cannot figure out how to refine HTB to get this behaviour: I need that class "p2p" should be the last one to get some link capacity. If I set both RATE

Hi all! I''m working in a " _really_ end user simple", yet powerfull, flexible, scalable, GPL htb/htb-init front end, but now, in the "test fase" im facing an utlimate problem... Absoult minimalistic scenario: #Use a FIXEDFONT to read this #inet-ethx-|FIREWALL|-lan-ethx <-> |client_host_1| # #FIREWALL class(rate,ceil) at lan-ethx

Hi, I''m using tc and HTB to shape my outgoing ADSL traffic. I was trying to make some graphs on the classes by meassuring the "sent bytes" of each class using rrdtool to store the data (as kbps after conversion). I expected that meassuring the root class I would get values similar that the ones I get measuring the interface counters but they differ by a large amount. Is

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

Hello! I need to switch from htb2 to htb3, because of speed issues (for me, htb2 is unable to handle more then 100mbit duplex with ~550 classes), kernel profiling shows htb_dequeue_prio at 1st place with 3x isolation. So, I''ve moved from 2.4.19 to 2.4.25 kernel (hi-pac for classification/marking and htb3 for queueing), and traffic rate drop from 100 to 20mbit. What can be wrong? The

Hi, I have a typical configuration for my firewall/gateway box: single network card, with a pppoe connection to the DSL modem. I''m already successfully shaping the uplink (how come that the wondershaper.htb doesn''t use the ceil parameter? It should implement bandwidth borrowing!) but i found the ingress policy a little bit rough. I''d like to keep the traffic categories

Hi, I am trying to setup a shaper for my linux box and I am experiencing some problems. What I am trying to do is priorizing packets on the egress link, therefore I have setup some prio classes etc. The priorizing seem to work but the problem is that the ceil parameter doesnt seem to work on non leafs. This is what stats show: > class htb 1:1 root rate 3000bit ceil 3000bit burst 1602b/8 mpu

I am trying to do ingress flow control with htb + imq, and as could be expected it isn''t working well. It works a lot better when I keep the htb ceiling well below what the link can actually carry - I guess because htb gets to throttle the TCP fast start before it causes packets to be dropped. The only problem is wasting all that bandwidth hurts. It occurred to me that the bandwidth

Hi, I''m trying to perform some (what I consider) basic traffic shaping on our network utilising HTB. I have mostly reused the example on the lartc.org site: tc qdisc add dev eth0 root handle 1: htb default 10 tc class add dev eth0 parent 1: classid 1:1 htb rate 100mbit burst 24k tc class add dev eth0 parent 1:1 classid 1:10 htb rate 50mbit ceil 80mbit burst 19k tc class add dev eth0

Hi all, I have an average 2mbit multicast stream that once in a while bursts high (up to 20mbit/s) in short periods (about 200ms). Could anyone please help me with directions using tc for configuing leaky bucket shaping to this stream? I have a 5mbit/s ceiling. My system is running gentoo linux 2.6.14, and I have compiled in all QoS modules. Thanks. Oivind

With the below script, whenever I ping 10.0.16.10 (which matches the only filter I have), traffic still get''s sent to the default 1:2 class instead of 1:1 and I don''t know why... Any hints? (kernel 2.6.12, iproute2-2.6.15) tc qdisc del dev eth0 root > /dev/null 2>&1 tc qdisc add dev eth0 handle 1: root htb default 2 tc class add dev eth0 classid 1:1 parent 1: htb rate

Thanks for quick reply Andreas! > Every class is allowed to use bandwidth as long as it does not have to > borrow (the specified rate is guaranteed). Prio in HTB only affects > borrowing bandwidth from other classes... In the example below, the class > 1:5 should be allowed to borrow bandwidth before 1:14 does. Thats exactly what I want from HTB to do..to prio the borrowed bandwidth.
