Hi jonathan, This is how i configured the testbed:
I have a windows 8 laptop connected directly on the tplink/openwrt router. Tplink is also connected to a gigabit switch. So, i thought to make some file uploads from a linux samba file server connected to the switch to my windows 8 laptop, through SMB protocol (which uses TCP). In order to create the bottleneck, tplink router has two 10/100mbits ports. So, i restricted the port connected to the switch to 10Mbit half duplex. Also, i tried to decrease interval and target options in order to obtain a latency, for connections estabilished while upload is flowing, lower that 5 ms. So i set target at 2ms and interval to 5ms. So this is the schema: laptop----tplink---switch---linuxserver where tplink is routing subnets. If i ping "linux server" i get very high latencies...and if i ping other PCs connected to the switch, i get about 10ms latencies. I also tried to lower target at 1 ms and interval at 2ms, but i see the same effects. If i disable fq_codel, i get always the same result. Can you explain me where i'm going wrong?

So, i configured tc to make fq_codel the default queuing algorithm for 2 eth ports available on the router (leaving unchanged default values). So, i started some TCP sessions through my Windows client and I loaded the available bandwidth...but the test wasn't going as expected because i experienced packet loss and high delays as i did when the default simple fifo queue was the default queue. Is there something that i'm not understanding?
