similar to: HFSC and default qdisc backlog

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 trying to get a handle on hfsc.

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

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

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, 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

I have important question about bandwidth allocation statistic show when i''m use "tc -s -d class ls dev eth2" At first, before testing I think "work" parameter from this command are real bandwidth in each class but when i''m calculate this parameter ... it''s too big number ... like it''s not a bandwidth rate and it''s may be some

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

Hello I have few questions regarding tc functionality (qdiscs, classes, etc.) when vlans are in use. For example, consider interface eth0, for which I create and extra vlan with vconfig, let''s say eth0.11. Then using tc I can add usual things - qdiscs, filters, ... - to both eth0 and eth0.11. The questions are: - on which interface - virtual or real, should I actually use tc ? Or

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

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

Dear Community, sorry for the somewhat dumb question. Maybe someone has any pointer to how to setup the RED queue to mark pakets with ECN. In particular what are appropriate parameter settings for limit, min, max, etc. All my trials end up with either "RTNETLINK answers: Invalid argument", although the command line (at least for me) looks fine in regard to what is said on the

Hello, I have recently started looking at tc and iptables. I have an htb-queue with two classes 1:10 and 1:20 where 1:20 is the default. Then I use iptables to mark all packets I send out on eth1. I then filter marked packets into class 1:10. I expected all packets sent on eth1 to end up in class 1:10, but some packets still go to 1:20. Did I do it wrong? Thank you for any help. regards, David

hmm HFSC ? where can i find more informations and examples about the *linux* HFSC ? http://trash.net/~kaber/hfsc/ does not help here -- _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

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

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

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

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

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

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
