htb on Gigabit Interfaces | |
| [Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] | |
Hi every body I have a linux server with Intel(R) Xeon(TM) CPU 3.20GHz , and 2 Gigabit of RAM , kernel version 2.6.22.6 , and 2 Intel 82541PI Gigabit Ethernet controllers In simple situation i would like to limit bandwidth for 2 customers 1) ( to 34 Mb/s ) and 2) 68 Mb/s . My conf is as below ///////////////////////////////////////////////////// #IFACE FACONG THE CUSTOMERS /sbin/tc qdisc add dev eth0 root handle 1:0 htb #IFACE FACING THE INTERNET /sbin/tc qdisc add dev eth1 root handle 1:0 htb /sbin/tc class add dev eth0 parent 1:0 classid 1:1 htb rate 150mbit quantum 30000 /sbin/tc class add dev eth1 parent 1:0 classid 1:1 htb rate 150mbit quantum 30000 #second customer download /sbin/tc class add dev eth0 parent 1:0 classid 1:2 htb rate 68mbit ceil 68mbit quantum 30000 #seconf customer upload /sbin/tc class add dev eth1 parent 1:0 classid 1:2 htb rate 68000kbit ceil 68000kbit quantum 30000 # first customer download /sbin/tc class add dev eth0 parent 1:0 classid 1:3 htb rate 34mbit ceil 34mbit quantum 30000 # first customer upload /sbin/tc class add dev eth1 parent 1:0 classid 1:3 htb rate 34mbit ceil 34mbit quantum 30000 #then iptable classify rules #TO_FIRST CUSTOMER /opt/sbin/iptables -t mangle -I POSTROUTING -o eth0 -d $DESTINATIONIP -j CLASSIFY --set-class 1:2 #FROM_FIRST CUSTOMER /opt/sbin/iptables -t mangle -I POSTROUTING -o eth1 -s $SOURCEIP -j CLASSIFY --set-class 1:2 #TO_SECOND CUSTOMER /opt/sbin/iptables -t mangle -I POSTROUTING -o eth0 -d $DESTINATIONIP -j CLASSIFY --set-class 1:3 #FROM_SECOND CUSTOMER /opt/sbin/iptables -t mangle -I POSTROUTING -o eth1 -s $SOURCEIP -j CLASSIFY --set-class 1:3 ///////////////////////////////// For the customer with 34 Mb/s of bandwidth i can hardly reach 8 Mb/s and at this point i can notice an increased number of packets in the htb scheduler queue . With the tc ( htb disabled ) the line rate of nearly 100 Mb.s of the customer can be reached easily Is there any special tunning or conf that should be done considering the gig interfaces in place Thank you Hysen Hoxha AlbTelecom Albania _______________________________________________ LARTC mailing list LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
