Hello Martin, Thank you for you help last time, I got the previous working (HTB1 & Ethloop1) but when I increase the rate and ceil (HTB2 & Ethloop2), the outcome is quite different. The different between cases is he rate and ceil are 10 times bigger than the other. Please take a look and I gusess this is the originl for the problem I post in the previous mail. HTB1: 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 ceil 100kbps ./tc class add dev lo parent 1:1 classid 1:2 htb rate 40kbps ceil 100kbps ./tc class add dev lo parent 1:2 classid 1:10 htb rate 30kbps ceil 100kbps prio 0 ./tc class add dev lo parent 1:2 classid 1:11 htb rate 10kbps ceil 100kbps prio 1 ./tc class add dev lo parent 1:1 classid 1:12 htb rate 60kbps ceil 100kbps 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 Ethloop1: # 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 excess 0 P 0 0x10010 0 P 1 0x10011 0 P 2 0x10012 # start all flow at defined rate 0 R 0 30k 0 R 1 10k 0 R 2 0 # Create extra at 1:12 and borrow this to 1:2 <------?
