Hello, I’ve read this Article avout VOIP and HFSC http://automatthias.wordpress.com/2006/06/30/hfsc-and-voip/ I’ve got few questions ? Considering this tc class add dev $DEV parent 1:1 classid 1:2 hfsc \ rt m1 ${UPLINK}kbit d 50ms m2 $[1*$UPLINK/10]kbit \ ls m1 ${UPLINK}kbit d 50ms m2 $[3*$UPLINK/10]kbit \ ul rate ${UPLINK}kbit rt = realtime curve ls = linksharing curve but m1 = ? m2 = ? d =

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 to me ... My question is In HTB tc command question 1. I''m use opensource (Mastershaper) for help to config traffic control but when i''m try to config HTB, I''m doubt about

Hello, I just found the great howto and started shaping my internet connection. The howto''s last update is a liitle in the past now so I have some questions about how things are done the best way nowadays ;-) To ensure a stable and low latency voip communication I added an HFSC qdisc to device ppp0 (1 Mbit SDSL). There are two classes (by now): One for SIP and RTP and one for the

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

My problem with HFSC tc command is ... tc command''s HFSC have a lot parameter with 4 curve type SC curve -> umax dmax rate LS curve -> umax dmax rate RT curve -> umax dmax rate UL curve -> umax dmax rate so i''dont know which parameter are appropriate for my test case such real time class which curve are appropriate and good working result. my assumption about

Hopefully someone has a suggestion on how I might do this...as I can''t figure it out :( I need to be able to set up a group of seperate users who have a "bandwidth pool" they share, but also be able to limit their individual bandwidth as well. Example: I have 5 customers and would like to be able to provide them with a maximum of 256Kbit each, with a CIR of 33%. To do this,

I am investigating changing our broadband bandwidth control scripts over to HFSC. What I would like to accomplish is this: { * DOWNLOAD * I need a download class for each user (we''ll call it Class 1) that offers a minimum of lets say 384Kbps and a maximum of 1.5Mbps. The rates between 384Kbps and 1.5Mbps should be shared among all users. Each user should always be able to get at

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

hi all, long time since i posted on the list. just wondering if anybody has played around with hfsc and if so could he/she share their info on it thanks adrian -- To mess up a Linux box, you need to work at it; to mess up your Windows box, you just need to work on it. _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl

Hello, I''ve got somes questions about Bridge and QOS ... I''ve got a serveur with 2 interfaces eth0,eth1 inside br0 bridge ... nothing of special ... If I understand all, normally I should configure TC class and qdisc on each physical or use ebtables to manage packets on output ... right ? I''ve attached my qos_script that hsfc and layer7 module. I use only Iptables

Dear List, I am wanting to perform some traffic shaping as the subject of this email suggests. What I am wanting to do is this; I would like to have traffic shaping performed on the following protocols: HTTP, RDP, GRE, PPTP, SIP and IAX. Obviously I would like to have highest priority set for voice packets so much so that the general http traffic does not impede on the voice packets. I

I have to match my packets based on MAC address, which I cannot do in the POSTROUTING chain, so I do it in PREROUTING using MARK. Then, I match on the MARK in the POSTROUTING chain to do a CLASSIFY. But this does not seem to work: wireless-r1 bwlimit # iptables -L -v -n -t mangle Chain PREROUTING (policy ACCEPT 3353K packets, 941M bytes) pkts bytes target prot opt in out source

Hi All, I''m trying to create a contended section of bandwidth using IMQ. I have the imq0 device up and running, with traffic passing through it. Firstly, I need to throttle the entire device imq0 to 2mbit/s. I would then like to add throttle rules for individual IP addresses, allowing them to pass up to 512kbit/s each, as long as imq0 has not reached its 2mbit/s. The configuration

I don''t understand the following: root@jmnrouter:~# tc -s class ls dev vlan1 && tc -s qdisc ls dev vlan1 class hfsc 1: root Sent 0 bytes 0 pkts (dropped 0, overlimits 0) period 0 level 2 class hfsc 1:1 parent 1: sc m1 0bit d 0us m2 220000bit ul m1 0bit d 0us m2 220000bit Sent 0 bytes 0 pkts (dropped 0, overlimits 0) period 31304 work 7533852 bytes level 1 class hfsc 1:10

Hi, I''m trying to get a handle on hfsc. Here is my configuration: root@jmnrouter:/jmn# tc class show dev vlan1 class hfsc 1: root class hfsc 1:1 parent 1: ls m1 0bit d 0us m2 225000bit ul m1 0bit d 0us m2 225000bit class hfsc 1:10 parent 1:1 rt m1 191000bit d 25.0ms m2 135000bit ls m1 0bit d 0us m2 135000bit ul m1 0bit d 0us m2 225000bit class hfsc 1:20 parent 1:1 rt m1 22008bit d

I''m using HFSC to limit bandwidth for our wireless customers. However, I''d also like the bandwidth prioritized based on packet type. This is what I''m trying right now, and I''d just like some input from anyone out there knowledgeable in this on whether it does what I want it to do: Eth1 -> HFSC ........|-> HFSC (User1) (Min 512 Kb, Max 1024 Kb, Burst 1536

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

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Greetings all, Working in concert with the original authors, Klaus Rechert and Patrick McHardy, I have translated their article "HFSC Scheduling mit Linux" [0] on Hierarchical Fair Service Curve (HFSC) into English [1]. http://linux-ip.net/tc/hfsc.en/ Although the original content is not available directly from their website,

When I start my script: * - Creating classes on br1 for upload control ... * - tc class add dev br1 parent 2:0 classid 2:46 hfsc ls m1 576.0Kbit d 2000ms m2 192.0Kbit ul m2 384Kbit ... [ ok ] * - tc class add dev br1 parent 2:46 classid 2:47 hfsc sc umax 1500b dmax 30ms rate 80Kbit . [ ok ] * - tc class add dev br1 parent 2:46 classid 2:48 hfsc ls m2 152.0Kbit ul m2 152.0Kbit

HTB versus HFSC, both qdisc offer the same kind of service, if you want to see comparative test results, go to http://www.rawsoft.org at the line "TEST RESULTS" you will find the results for a sharing test and a burst test. You will see that both qdisc are good. _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl
