Hi,
I'm trying to use prio qdisc with htb, however not the "usual" way (like for
example FairNAT).
Here is my idea:
Root has HTB shaping traffic to link speed -> then goes PRIO queues -> each
prio queue has HTB with sublasses for each user, should look like this:
1: htb qdisc
|
1:1 htb class
/|\
/ | \
10:1 10:2 10:3 prio queues
| | |
20: 30: 40: htb qdiscs
/ | \
20:1.... 30:1... 40:1... htb classes
Then, if I'm right, when there is traffic in prio qdisc 1 to fully load link,
users would get it distributed evenly but any low priority connections in
qdiscs 2,3... would starve. Which is exactly what I want.
Problem is, when I add filters to enqueue in HTB "below" prio qdisc, they
aren't working.
I'm tried to make simplified version first:
tc qdisc add dev eth0 root handle 1: htb
tc class add dev eth0 parent 1: classid 1:1 htb rate 3000kbit
tc qdisc add dev eth0 parent 1:1 handle 10: prio
tc qdisc add dev eth0 parent 10:1 handle 20: htb
tc class add dev eth0 parent 20:0 classid 20:1 htb rate 3000kbit
tc qdisc add dev eth0 parent 10:2 handle 30: htb
tc qdisc add dev eth0 parent 10:3 handle 40: htb
tc class add dev eth0 parent 30:0 classid 30:1 htb rate 3000kbit
tc class add dev eth0 parent 40:0 classid 40:1 htb rate 3000kbit
tc filter add dev eth0 protocol ip parent 1: prio 0 handle 4 fw flowid 40:1
all packets are marked with 4, but none gets to 40:1

{setting flowid to 1:1 works as expected}
I can't find where my mistake lies,
any suggestions or pointers would be helpfull.
