Message-Id: List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: lartc@vger.kernel.org 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' ?
