Subject: [LARTC] Classless Queues in series...
Date: Wed, 12 Mar 2003 17:07:52 +0000	[thread overview]
Message-ID: <marc-lartc-104748887802810@msgid-missing> (raw)


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?


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' ?

Regards, Ben.
