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,

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

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

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

now, i''m learning and try to read a lot of article about tc command in linux for setting traffic shaper. but i''m doubt about In the theory about tc command ... In general, we define class under root qdisc but Is it can be possible ???? If we define another qdisc under root qdisc, Can i do it? because i have just read tc command syntax and i found this point ... syntax: tc qdisc

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

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

Hello, I have finally managed to understand HFSC up to a level which allowed me to create a QoS script which maintains low VoIP latency while running stuff like eMule. Unfortunately, HFSC seems to have a severe bug. Why do I consider this as a bug defenitely? Well, my script runs without any errors, then QoS works perfectly for some hours, no error messages in kernel log. Then randomly the

-----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,

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

Hi, Is it possible to attach another qdisq under a HFSC classfull ? I try it and the configuraton works : $TC qdisc add dev $dev root handle 1: hfsc default 30 $TC class add dev $dev parent 1: classid 1:1 hfsc sc rate ${RATE}mbit ul rate ${RATE}mbit $TC class add dev $dev parent 1:1 classid 1:10 hfsc rt umax 1500b dmax 30ms rate 200kbit $TC class add dev $dev

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! Do you know somthing about hfsc and bps? There''s no output for speed only for packets.

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
