Ben,
: I need (or would at lest live very much :) to use two Classless Queues
: in series.
:
: I can't see in the HOWTO how this is done, but guess at something like:
:
: tc qdisc add dev eth0 root handle 1: sfq (etc)
: tc qdisk add dev eth0 parent 1: tbf (etc)
:
: Am I on the right lines here?
A classless queueing discipline cannot contain another queueing
discipline.
A classful queueing discipline can contain classes and leaf queueing
disciplines.
In other words:
- a classless queueing discipline is by definition, a terminal qdisc
- a classful queueing discipline can be terminal or
- can contain a class, which can be terminal or
- can contain another queueing discipline
Does that help?
: I also have a small problem with TBF... From the HOWTO sec 9.2.2, it is
: surgested that a value for the 'burst' should be:
:
: "For 10mbit/s on Intel, you need at least 10kbyte buffer if you want to
: reach your configured rate!"
:
: Therefore: burst => rate * (8 / 1000)
:
: However, I find using this I get stall on ftp and other common
: protocols, when they get above the throttle rate, with low bandwidths
: (eg, 64kbit/sec). -- Or I completelly fail to understand the above
: statement...
:
: Does any person have a better method for calculating a good value for
: 'buffer' ?
I'm afraid I can't help you on this question.
-Martin
