Thank you for your reply :)
I try to follow chapter 6 on your user guide.
1:1
/ \
1:2 1:12
/ \
1:10 1:11
(prio1) (prio2)
If 1:12 don't have any traffic, all the BW on 1:12 can be assigned to 1:2,
is that right?
I try to put all these extra (from 1:12) to 1:10, my htb script is as
follows, and I use ethloop to test and I found that 1:10 will not get the
extra from 1:12. Could you tell me where I make a mistake? Thank you.
echo Clean all the tc setup
./tc qdisc del dev lo root
./tc qdisc add dev lo root handle 1: htb default 12
./tc class add dev lo parent 1: classid 1:1 htb rate 100kbps
./tc class add dev lo parent 1:1 classid 1:2 htb rate 40kbps
./tc class add dev lo parent 1:2 classid 1:10 htb rate 30kbps prio 0
./tc class add dev lo parent 1:2 classid 1:11 htb rate 10kbps prio 1
./tc class add dev lo parent 1:1 classid 1:12 htb rate 60kbps
echo qdisc
./tc qdisc add dev lo parent 1:10 handle 20: pfifo limit 5
./tc qdisc add dev lo parent 1:11 handle 30: pfifo limit 5
./tc qdisc add dev lo parent 1:12 handle 40: sfq perturb 10
Input for ethloop:
# lo will be used to TX and RX
0 i 0 lo
0 i 1 lo
0 i 2 lo
# set simulation packet size to 1k
0 S 0 1k
0 S 1 1k
0 S 2 1k
# flow 0 AE, flow 1 BE, flow 2 EF
0 P 0 0x10010
0 P 1 0x10011
0 P 2 0x10012
# start all flow at defined rate
0 R 0 30000
0 R 1 10000
0 R 2 60000
# Create extra at 1:12 and borrow this to 1:2 <------?
5000 R 0 30000
5000 R 1 10000
5000 R 2 0
# 1:10 and 1:11 and 1:10 should get higher value <------?
15000 R 0 40000
15000 R 1 20000
# finish at 8sec
25000 X 0 0
Result is to long, I use gnuplot and found that 1:10 at most get 30000.
Thank you for you help.
