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''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

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.

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, I’ve read this Article avout VOIP and HFSC http://automatthias.wordpress.com/2006/06/30/hfsc-and-voip/ I’ve got few questions ?

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

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

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 to me ... My question is In HTB tc command question 1. I''m use opensource (Mastershaper) for help to config traffic control but when i''m try to config HTB, I''m doubt about

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 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

Hello, this is my first post here and it is about the behavior of a HFSC class with a two piece-wise linear service curve. My goal is to separate audio streams from bulk traffic. To keep it simple a use two classes one high priority realtime and the other for the rest. Example: tc qdisc add dev ppp0 root handle 1: hfsc default 11 tc class add dev ppp0 parent 1: classid 1:1 hfsc rt m1 400kbit d

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

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 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

-----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,

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
