similar to: HFSC again.

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, 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

Hello, First I want to point out that I''m not so familiar with HFSC, since there not so much info online. But here is my script: ${TC} class add dev ${LAN_IFACE} parent 1:0 classid 1:1 hfsc ls rate 100mbit ul rate 100mbit ${TC} class add dev ${LAN_IFACE} parent 1:1 classid 1:2 hfsc ls rate 90mbit ul rate 90mbit ${TC} class add

Hi! Do you know somthing about hfsc and bps? There''s no output for speed only for packets. Doesn''t hfsc support such a field? tc -s class show dev eth0 class hfsc 1: root Sent 0 bytes 0 pkt (dropped 0, overlimits 0 requeues 0) rate 0bit 0pps backlog 0b 0p requeues 0 period 0 level 2 class hfsc 1:11 parent 1:1 sc m1 0bit d 18.0ms m2 1000Kbit ul m1 0bit d 0us m2

hi, I would like to use the HFSC scheduler for my QoS. I''ve 4 class and 2 of them need to control the bandwidth and the latencies so I think I must use HFSC. So I read some doc ( http://del.icio.us/tag/hfsc ) but its not very clear. I make some tests with differents parameters but I''m not able to use correctly this scheduler: $TC qdisc add dev $dev root handle 1: hfsc default 40

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

Hello, I''m having such problem with HFSC with following config: + tc qdisc del dev eth3 root + tc qdisc add dev eth3 root handle 1: hfsc default 2 + tc class add dev eth3 parent 1: classid 1:1 hfsc ls rate 512kbit ul rate 512kbit + tc class add dev eth3 parent 1:1 classid 1:2 hfsc ls rate 2kbit ul rate 400kbit + tc class add dev eth3 parent 1:1 classid 1:3 hfsc ls rate 32kbit ul rate

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

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

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 I''m moving to hfcs (mostly succesfuly:) ), but I''ve encountered a strange problem: When I download something from this server using wget (one thread) via an idle uplink, I get no more than 130 kbit/s, and when I''m using prozilla (or start more wgets), I get about 200 kbit, but still it''s not all the link can do (240) - the rest remamins unused. Is this

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 ?

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 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.

Hello, I''m using Linux kernel 2.6.x and tc (from iproute2 package). I''m trying to use HTB or HFSC scheduler in order to limite the rate of outgoing packets and also in order to minimiez delay for RTP stream. But I didn''t suceed in having this 2 QoS services working. I use Iptables in order to classify packets. Here is my HFSC conf. In fact the pings that i send from

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

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
