I have a lot question about tc-command because now i''m doing research to compare performance between HTB and HFSC so i''m doubt a lot thing and your reply are so very helpful me ... my question is 1. I''m use opensource (Mastershaper) for help to config traffic control but when i''m try to config HTB, I''m doubt about in each chain must identify fallback

now i''m read a lot of knowledge paper about traffic control in linux because now i''m try to develop and research about traffic shaper so can everybody tell me about my topic ... Is it can do for real???? my topic is " now, many organization use traffic shaper for control traffic and bandwidth because don''t want something example some mac address, ip address,

Hi all, Long email but please be patient :) I am part of EHAS [1], a non profit organization which main goal is to improve the Healthcare assistance in isolated rural areas in developing countries. Recently we have developed a long distance Wi-Fi network in Cuzco (Peru). This network provides connectivity to 12 nodes (they are in fact Health Centers). As VoIP is a essential service in this

Hi,lartc！ I read some article for linux qos,who can tell me htb and hfsc,which better? I'm not find about hfsc information. thanks your help. _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc

Hello I''ve been messing with traffic controlling for some time and encountered singularities I''d like to talk about. First explaining of my pow (can''t tell how much each point is relevant) Box with Debian, Intel PII*2 old and fancy:), ADSL link with dyn IP, some servers (f. ex. squid), loc net with dhcp, (although IP statically given by MAC); MASQ. Such circumstances

Attaching WRR to a hfsc ot htb class after a while i will get all packets drop and syslog full of HFSC or HTB : Non-work-conserving qdisc any ideas ? -- []''s Salatiel "O maior prazer do inteligente é bancar o idiota diante de um idiota que banca o inteligente".

I have been looking at the hfsc for some time as a replacement or at a class that can be used like htb. But I seem to have run into a problem. With htb classes it is easy to make three or more levels of priority for a connection. All you need to do is to make classes and give them different prio levels. But it seems like you can only define a real-time bandwidth and a link sharing bandwidth.

Hello list, I am now using hfsc for QOS. I have something like this: tc qdisc add dev ethx root handle 1: hfsc default 9 tc class add dev ethx parent 1: classid 1:1 hfsc ls m2 70mbit ul m2 70mbit tc class add dev ethx parent 1:1 classid 1:9 hfsc ls m2 7mbit #DNS stuff follows tc class add dev ethx parent 1:1 classid 1:2 hfsc rt m1 12mbit d 1ms m2 1mbit #Half-life tc class add dev ethx parent

1. HFSC have 4 curve such sc, rc, ls, ul and 1.1 In leaf class can specify rc for guarantee service (bandwidth and delay) and If want to sharing fairness exceess service, we must specify ls and ul curve too (ls curve with paramater m2 specify at lease sharing bandwidth in that class will receive and ul curve mean maximum bandwidth in that class will receive) so i''m doubt .. about if i

Hello All, I am trying to prioratize VOIP traffic from data. The follwing link says that HFSC is better than HTB for shaping VOIP traffic. http://www.voip-info.org/wiki-QoS+Linux+with+HFSC I am in search of good documentation to start with HFSC, I am unable to understand the parameters used. I "googled" a lot to find on how to use HFSC, but no luck. Can anyone of you get me a link To

Hi: I am using a machine with the 2.4.26 kernel, and trying to compare the performance of the HTB qdisc with the HFSC one. I have the following simple script that allows me to have a video stream on port 1234 while it limits a ttcp UDP stream so that the video stream is unimpaired. #!/bin/bash tc qdisc add dev eth0 root handle 1: htb default 12 tc class add dev eth0 parent 1: classid 1:1

i doubt about ruleset in mastershaper demo about why use hfsc at leaf class but inner class use htb??? how different for manage traffic like it???? /bin/false qdisc add dev eth1 handle 1: root htb default 1 /bin/false class add dev eth1 parent 1: classid 1:1 htb rate 2048Kbit ######### Incoming Rules ######### chain HB /bin/false class add dev eth1 parent 1:1 classid 1:21 htb rate 128Kbit ceil

Hi First I must say that I`am an author of HTB auto-configurator (so I know some about QoS under linux) and I have read a lot of articles about HFSC, but I still don`t know how to configure this algoritm properly. Maybe somone can help me and write a little example for me (the best will be Patrick McHardy who has ported HFSC to linux) - please just three queues. My situation: Let say I have 1Mbit

after i use "tc -s -d class ls dev eth0" will show statistic data about HFSC ,like this root@ubuntu:/home/shaper# tc -s -d class ls dev eth2 class hfsc 1: root Sent 0 bytes 0 pkts (dropped 0, overlimits 0) period 24 work 13844792199226589188 bytes rtwork 20937281664 bytes level 3461036864 class hfsc 1:11 parent 1:1 sc m1 30720Kbit d 10.0ms m2 30000bit ul m1 0bit d 0us m2

I stumbled upon a problem while upgrading Ubuntu 13.04, Shorewall version from 4.4.26.1 to 4.5.16.1. Everything was working fine before, after upgrading the script wouldn''t start. First some config files. tcdevices: #INTERFACE IN-BANDWIDTH OUT-BANDWIDTH OPTIONS REDIRECTED eth1 - 6300kbit hfsc,classify ifb0 - 6300kbit hfsc
