The default qos-scripts for openwrt are being tested in south africa right now as part of the first bismark 'capetown' deployment of a whole bunch of wndr3700v2 routers.<br><br>Bismark contains extensive debloating of the ar71xx, and ath9k device drivers and <br>
shortened txqueues.<br><br>On the plus side, the qos-scripts hold latencies down below 400ms for priority traffic.<br><br>On the minus sides, I'm not seeing red kick in (no packet loss to speak of), ecn is not being negotiated on tcp connections to SA(??), and single stream downloads are at about 3/4 of the overall bandwidth available.<br>
<br>I would be very interested in a little analysis of the packet captures and data contained in bug:<br><br><a href="http://www.bufferbloat.net/issues/171">http://www.bufferbloat.net/issues/171</a><br><br>and email thread:<br>
<br><a href="https://lists.bufferbloat.net/pipermail/bismark-devel/2011-May/000177.html">https://lists.bufferbloat.net/pipermail/bismark-devel/2011-May/000177.html</a><br><br>I've also setup a wndr3700v2 box in Georgia with these QoS settings in place, and some big files worth downloading. It is temporarily at:<br>
<br><a href="http://gw.lab.bufferbloat.net/capetown/capetown-wndr3700v2/">http://gw.lab.bufferbloat.net/capetown/capetown-wndr3700v2/</a><br><br clear="all">Experience the pain of the Internet on another continent! (note that the gw is up on ipv6 as well)<br>
<br>(if you merely want a copy of the near final capetown release of bismark for a wndr3700v2, <br> you can download it without the simulated pain, at:<br><br><a href="http://mirrors.projectbismark.net/downloads/capetown/capetown-wndr3700v2/">http://mirrors.projectbismark.net/downloads/capetown/capetown-wndr3700v2/</a><br>
<br>only the "v2" is supported.<br><br>)<br><br>SFB is also in this release, but lacking good scripts for it...<br><br>So, out of the 100+ papers on RED93, which one applies best in this situation? does RED93 drop packets properly when ECN is not available? Etc.<br>
