Hi there, I just started playing around with prioritizing traffic. However I do have some questions left :P I am using the following setup: tc qdisc add dev ppp0 root handle 1: prio tc qdisc add dev ppp0 parent 1:1 handle 10: sfq tc qdisc add dev ppp0 parent 1:2 handle 20: tbf rate 61kbit latency 50ms burst 1540 tc qdisc add dev ppp0 parent 1:3 handle 30: sfq I use the mangle table of iptables to force the TOS bit (based on the tcp src or tcp dst port) in order to sent interactive traffic to band 0 (1:1), bulk traffic to band 2 (1:3) and remaining traffic to band 1 (1:2). This seems to work. I do see packets flow trough the mangle table (iptables -t mangle -vnL) and I do see interactive traffic go band 0 , etc.. (tc -s qdisc ls dev ppp0). However I do not notice much of a difference. While downloading some linux kernels a telnet session still slows down a lot :( Any ideas how this might be possible?
