I can mess around with qdisc on it, since the web ui QoS setup just creates qdisc settings to correspond. Can I have a copy of the red settings commands you used? My router basically creates a HTB with 3 SFQ for the QoS and when I poked at it, it looked like it would let me change the SFQ to RED. But at that time, I did not have the time to really poke around with it. # tc -s -d qdisc show qdisc htb 1: dev eth0 r2q 500 default 10 direct_packets_stat 4 ver 3.17 Sent 7150514979 bytes 10846403 pkt (dropped 0, overlimits 0 requeues 0) rate 154592bit 14pps droprate 0bit backlog 0b 0p requeues 0 qdisc sfq 10: dev eth0 parent 1:10 limit 128p quantum 1514b flows 128/1024 perturb 10sec Sent 7150491288 bytes 10846212 pkt (dropped 0, overlimits 0 requeues 0) rate 154592bit 14pps droprate 0bit backlog 0b 0p requeues 0 qdisc sfq 110: dev eth0 parent 1:110 limit 128p quantum 1514b flows 128/1024 perturb 10sec Sent 0 bytes 0 pkt (dropped 0, overlimits 0 requeues 0) rate 0bit 0pps droprate 0bit backlog 0b 0p requeues 0 qdisc sfq 120: dev eth0 parent 1:120 limit 128p quantum 1514b flows 128/1024 perturb 10sec Sent 22796 bytes 185 pkt (dropped 0, overlimits 0 requeues 0) rate 0bit 0pps droprate 0bit backlog 0b 0p requeues 0 qdisc pfifo_fast 0: dev ra0 root bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1 Sent 19767464443 bytes 29505220 pkt (dropped 0, overlimits 0 requeues 0) rate 0bit 0pps droprate 0bit backlog 0b 0p requeues 0 qdisc pfifo 8009: dev eth0.3900 limit 1p Sent 6661359886 bytes 9028157 pkt (dropped 0, overlimits 0 requeues 0) rate 154128bit 14pps droprate 0bit backlog 0b 0p requeues 0 # eth0 =3D LAN interface ra0 =3D WLAN interface eth0.3900 =3D Ethernet WAN interface Its got an old kernel, with lots of patches to kernel I think, so not sure if its easily done to create a new kernel for it either. # uname -an Linux P-2612HNU-F3 2.6.20.19 #44 Wed Mar 30 10:58:43 CST 2011 mips unknown # cat /proc/cpuinfo system type : AR9 processor : 0 cpu model : MIPS 34K V4.12 BogoMIPS : 261.32 wait instruction : yes microsecond timers : yes tlb_entries : 16 extra interrupt vector : yes hardware watchpoint : yes ASEs implemented : mips16 dsp mt VCED exceptions : not available VCEI exceptions : not available # cat /proc/meminfo MemTotal: 124096 kB MemFree: 27316 kB Buffers: 7512 kB Cached: 64772 kB SwapCached: 0 kB Active: 44640 kB Inactive: 37276 kB SwapTotal: 0 kB SwapFree: 0 kB Dirty: 0 kB Writeback: 0 kB AnonPages: 9640 kB Mapped: 27800 kB Slab: 9620 kB SReclaimable: 1388 kB SUnreclaim: 8232 kB PageTables: 760 kB NFS_Unstable: 0 kB Bounce: 0 kB CommitLimit: 62048 kB Committed_AS: 43156 kB VmallocTotal: 1048404 kB VmallocUsed: 4164 kB VmallocChunk: 1043016 kB # Pedro On Wed, May 11, 2011 at 1:22 AM, Dave Taht wrote: > I did a preliminary test of a bismark router with ECN and red enabled usi= ng > a lightly modified > version of openwrt's (nbd's) qos-scripts, doing a scp upload from my lapt= op > to a server at bufferbloat.net. > > I artificially throttled the uplink at 1Mbit=A0 and downlink to 10Mbit (t= he > measured real values are 24Mbit and 67Mbit respectively) for this test. > > (there are a few other qdiscs in use, too) > > > I won't claim to have configured red properly but... > > http://www.teklibre.com/~d/bismarkredc2d_owin.png > > Look better than usual bufferbloat to y'all? > > This was over ipv4.
