HFSC and prioritization
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

HFSC question??
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

HFSC Advanced Limiting
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

HFSC
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.

tc qdisc add dev eth0 root handle 1: htb default 12

Can i attach another qdisc under classes or root qdisc?
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 ...

Some questions about hfsc
I have been looking at the hfsc for some time as a replacement or at a
class that can be used like htb. But I seem to have run into a problem.
With htb classes it is easy to make three or more levels of priority for a
connection. All you need to do is to make classes and give them different
prio levels. But it seems like you can only define a real-time bandwidth
and a link sharing bandwidth.

Strange HFSC behavior - bug? my misconfiguration/lack of knowledge?
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.

Wanted Good Documentation on HFSC
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

Do you know somthing about hfsc and bps?
There''s no output for speed only for packets. Doesn''t hfsc support such
a field?

I’ve got few questions ?

ul rate ${UPLINK}kbit
rt = realtime curve
ls = linksharing curve
but
m1 = ?
m2 = ?
