Stef, remember the problem about DAP users? i have written a little scrip t=
o create 255 classes each for an ip of my segment, what do you think, am i =
mistaken anywhere?
I am not sure i am getting the concept right. The idea is=20
Total BW is lets say 255kbit

                   root 1:0

                         |
                        1:1 2kbit ceil 255kbit
                        / \ =20
                       /   \
 1kbit ceil 127kbit   1:2  1:4 1kbit ceil 128kbit
                       |    |
               pfifo  1:3  1:5 sfq

                         |
                        1:6 2kbit ceil 255kbit
                        / \ =20
                       /   \
 1kbit ceil 127kbit   1:7  1:8 1kbit ceil 128kbit
                       |    |
               pfifo  1:9  1:10 sfq                      =20

And soo on 255 times...

I now the rate of the classes add up to be more than the total BW but since=
 i am doing that for 2 ADSL working with multipath (loadbalanding) routing,=
 i think there will never be all users using one interface. Dont know if my=
 assumption is right..

To end up i have to set up a hashing table to create all the filters. The s=
cript to create the structure is the one on the bottom. What do you think? =
Am i going in the right direction or did i just completly missed what you w=
ere having in mind..? ( I have not set up the hashing table for filters yet)

#!/bin/bash
UPLINK00
DEV=3Deth0

IP=3D""

for ((a=3D1;a<255;a++))
do
 IP=3D$IP" "$a
done


b=3D1

for a in $IP
do
 let "c=3Db"

   tc class add dev $DEV parent 1: classid 1:$b htb rate 2kbit ceil 300kbit
 let "b=3Db+1"

   tc class add dev $DEV parent 1:${c} classid 1:${b} htb rate 1kbit ceil 1=
50kbit
 let "c=3Db"
 let "b=3Db+1"

   tc qdisc add dev $DEV parent 1:${c} handle ${b}: pfifo
 let "b=3Db+1"
 let "c=3Dc-1"

   tc class add dev $DEV parent 1:${c} classid 1:${b} htb rate 1kbit ceil 1=
50kbit
 let "c=3Db"
 let "b=3Db+1"

  tc qdisc add dev $DEV parent 1:${c} handle ${b}: sfq perturb 10
 let "b=3Db+1"

done
