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

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! 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''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, 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''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 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, 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

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

Hello mailing list, I don´t know how to use HFSC queuing discipline with tcng configuration language. I become always this error: syntax error near "hfsc" Is it possible, that tcng provides no support for this classful hfcs queuing discipline? Please help! thanks ----------------------------------------------------------------------------

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
