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...

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...

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 22500...

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 er...

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 pa...

-----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, Linux Magazin published the German article in 2/2005 [2]. The article is apparently slated...

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 alwa...

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 http://mailman.ds9a.nl/mailman/listi...

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

Hello list, I am now using hfsc for QOS.

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 th...

...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 [add/del] dev String [handle][root /ingress/ parent CLASSID] [QDISC_KIND] := {fifo /tbf/ prio/ cbq/ htb/ hfsc} from above syntax at [handle][root /ingress/ ****parent CLASSID] Is "parent CLASSID" mean we can define qdisc under class???? so this is my assumption about that. and Could you advise me about Is it can do for real???? //first .. define root qdisc tc qdisc add dev eth0 root handle 1:...
