hfsc and bps
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?

vlan interfaces and tc
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

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

iptables CLASSIFY and MARK not working?
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:

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.
