[LARTC] htb & bandwidth sharing

[Albert Martorell <albert@csc.unica.edu>]

Hi everybody!

I've been trying with htb and tc filter. It seemed to work fine, but
after testing with ethloop I've realized that traffic is not being
distributed through the leaves as I thought. When sending packets to
1:10 and 1:11 at the same time, there's no bandwidth sharing. There's no
traffic through 1:11 until traffic through 1:10 has finished. Though
I've tried assigning different prio's, 1:10 always gets more
bandwidth...

Here's the script that reproduces this behaviour:

tc qdisc add dev eth0 root handle 1: htb default 12 r2q 10
tc class add dev eth0 parent 1: classid 1:1 htb rate 600kbit ceil
600kbit
tc class add dev eth0 parent 1:1 classid 1:10 htb rate 200kbit ceil
600kbit
tc class add dev eth0 parent 1:1 classid 1:11 htb rate 200kbit ceil
600kbit
tc class add dev eth0 parent 1:1 classid 1:12 htb rate 200kbit ceil
600kbit
tc qdisc add dev eth0 parent 1:10 handle 20: sfq perturb 10
tc qdisc add dev eth0 parent 1:11 handle 21: sfq perturb 10
tc qdisc add dev eth0 parent 1:12 handle 22: sfq perturb 10

tc filter add dev eth0 protocol ip parent 1: u32 match ip sport 53
0xffff flowid 1:10
tc filter add dev eth0 protocol ip parent 1: u32 match ip src 1.2.3.4
match ip sport 80 0xffff flowid 1:11


Thanks in advance!
