Hi everyone,
I had a question about linux qos using the tc command.
I''m sorry if I''m mailing to the wrong list. I''d
appreciate
any redirection to the right one.
What I want to do is to converge several flows.
Is this possible with Linux ?I only found examples that fan out,
like the tree structure.
And was wondering if it''s possible to converge it.
I''ll show what I tried to do, in the drawing below.
And the script, half way done.
many flows here

# HTB qdisc
$ /sbin/tc qdisc add dev eth0 handle 1: root htb
# HTB classes
$ /sbin/tc class add dev eth0 parent 1:1 classid 1:11 \
htb rate 3Mbit burst 1000 prio 1
$ /sbin/tc class add dev eth0 parent 1:2 classid 1:12 \
htb rate 4Mbit burst 2000 prio 2
...
...
(say there''s N classes, m priorities)
$ /sbin/tc class add dev eth0 parent 1:3 classid 1:N \
htb rate 4Mbit burst 3000 prio m
# Filters
$ /sbin/tc filter add dev eth0 parent 1: protocol ip \
u32 match ip src 192.168.10.10 \
match ip dst 192.168.0.1 \
match ip dport 5001 0xff \
classid 1:1
$ /sbin/tc filter add dev eth0 parent 1: protocol ip \
u32 match ip src 192.168.10.10 \
match ip dst 192.168.0.1 \
match ip dport 5002 0xff \
classid 1:2
$ /sbin/tc filter add dev eth0 parent 1: protocol ip \
u32 match ip src 192.168.10.10 \
match ip dst 192.168.0.1 \
match ip dport 5003 0xff \
classid 1:3
I want to define another 3 QUEUES after this, and make all the
flows converge into those 3 QUEUES.
Would anyone please give me a clue, or an answer to this ?
Thanks in advance,
Hideaki

Hi Francesco, Thanks for the clue. In that case, how do I define the QUEUES ? If I defined the 3 queues with those leaves as the parents, I only could guide the flows that came through those parents. (since I cant define a qdisc that has several parents) I tryed with the u32 filter, and failed. Is there any specific filter you recomend ?
