i do, but, forget CS, my problem is that the prio don't work

here the script to start the discusion

$tc qdisc del $IF_EXT root
$tc qdisc add $IF_EXT handle 1: root htb default 2
$tc class add $IF_EXT parent 1: classid 1:9 htb rate 500kbit burst 6k
$tc class add $IF_EXT parent 1:9 classid 1:1 htb rate 500kbit ceil
500kbit burst 6k prio 1
$tc class add $IF_EXT parent 1:9 classid 1:2 htb rate  64kbit ceil
500kbit burst 6k prio 2

$tc filter add dev $IF_EXT protocol ip prio 2 parent 1: u32 \
        match ip protocol 1 0xff flowid 1:1

fizical ADSL 5mbit/700kbit, the desired: even the upload is full, i want
to have a wonderfull ping response

the problem is that the above script don't work, why????

and for your script below, nice marks, but the tc where is it???

C

P.S. Happy New Year!!!!
