questions about HFSC, VoIP and (dynamic) ingress shaping
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

ATM [Cell Tax]
I have read the thread at
http://mailman.ds9a.nl/pipermail/lartc/2006q1/018287.html
and still don''t know how to fix this problem. It appears alot of work
has gone into it but the HOWTO is so out of date it doesn''t even begin
to addresses this method.
So here are my questions
1. what is the current state of these patches? are they in a specific
version? do i have to patch myself?

simple TOS based setup vs more complex ones
Hi,
After reading section 9 of LARTC it seemed to me that a pure TOS based QoS setup with be sufficient for a small newtork. Interactive packets could have the highest priority, second highest for DNS and small HTTP packets and lowest prio for all others.
The advantage is that, the setup would be simply a couple of iptables lines, because the default pfifo_fast qdisc already implements

Dear all,
I have 3 backbones for my local network.

Bridge HFSC QOS questions ...
Hello,
I''ve got somes questions about Bridge and QOS ...
I''ve got a serveur with 2 interfaces eth0,eth1 inside br0 bridge ...

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.

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.

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

HFSC traffic loss bug, kernel 2.6.16.24
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.
