Hi all!!!
I do not know why my letter was sent back again and
again!!!
Trever said my
ceil value was wrong!!!
My test enviroment is local ethernet network, computer 18 has 10Mbit
network card, and HTB+BRIDGE box has two 100Mbit network card,
computer 29 and 26 have 100Mbit network card too. 26 and 29 link to HTB+BRIDGE eth0 by 100Mbit SWITCHER not HUB. My ceil parameter set to 10Mbit wrong? Yestoday, I found the
performace of HTB is related to r2q value and ceil value.
If I set ceil to 100kbps,set r2q to 1,it is ok. If I set ceil to 200kbps,set r2q to 1.tc always say "HTB: quantum of class 10001 is big, Consider r2q change". In my test environment that I first mentioned,I saw the same information. Can you tell me their relation??
This letter was sent yestoday,but sent
back this morning.I do not know why!!!

192.168.2.26

|------------- | HTB+BR box |--------
192.168.2.18
| eth0

| eth1
192.168.2.29

I want to limit the traffics when i download data from
192.168.2.18 to 26 or 29.
My script as following:
tc qdisc add dev eth0 root handle 1: htb default
10
tc class add dev eth0 parent 1:0 classid 1:1 htb rate
10Mbit
tc class add dev eth0 parent 1:1 classid 1:10 htb rate 1Mbit ceil 10Mbit prio 1
tc class add dev eth0 parent 1:1 classid 1:11 htb rate 7Mbit ceil 10Mbit prio 2
tc class add dev eth0 parent 1:1 classid 1:12 htb rate 2Mbit ceil 10Mbit prio 3
tc filter add dev eth0 parent 1:0 protocol ip prio 10 u32 match ip dst
192.168.2.26/32 flowid 1:11
tc filter add dev eth0 parent 1:0 protocol ip prio 10 u32 match ip dst
192.168.2.29/32 flowid 1:12
26 download from 18,26 can get
900kbytes/s. if 26 and 29 download simultaneously, 26 get
400kbytes/s while 29 get
500kbytes/s .
I had thought 26 gets more
than 7Mbit/s and 29 gets more than 2Mbit/s.
i do not know why
any idea any sugestion ! please tell me, I really appreciate your
help!!! |
