Hi! I'm trying to share a 64 kbits/s ISDN connection for FTP downloads and WWW. FTP should slow down WWW a little a possible. I tried HTB (with kernel 2.4.18) with the following (amongst other) settings: $TC qdisc add dev $IF root handle 1: htb default 20 $TC class add dev $IF parent 1: classid 1:1 htb rate 64kbit burst 2k $TC class add dev $IF parent 1:1 classid 1:10 htb rate 63kbit ceil 64kbit burst 2k $TC class add dev $IF parent 1:1 classid 1:20 htb rate 1kbit ceil 64kbit prio 1 $TC qdisc add dev $IF parent 1:10 handle 10: sfq perturb 10 $TC qdisc add dev $IF parent 1:20 handle 20: sfq perturb 10 FLT="$TC filter add dev $IF protocol ip parent 1:0" $FLT prio 1 u32 match ip sport 80 0xffff flowid 1:10 The packets pass through the respective classes. But FTP doesn't seem to be slowed down when WWW traffic starts. When doing http and ftp downloads at the same time, I expected the FTP side to slow down a lot, but during my tests the ftp download had more throughput than the http. Any thoughts?
