[SOLVED] How to divide internet speed on linux router?

sandeepc04 · 04-03-2013, 11:21 PM

Hi Good Morning Friends,

I need some help on linux router side,

I am planning to divide internet speed by using linux platform, I have Linux RHEL-5 Machine, and We are using 4MBPS speed of internet, and we are having 3 floor of clients,

Now here i wanted to give 1 floor 2MBPS and other 2 floors with 2MBPS speed to use,

Is it possible that we can divide internet speed on RHEL-5 (Any advance technology in routing for this)???

Thanks and Regards,
Sandeep CC

Hello.
I recommend you use shaping with the iproute package.
You need a 'tc' utility included in it.
Use HTB traffic shaping.
http://luxik.cdi.cz/~devik/qos/htb/manual/userg.htm

Not easy to understand (to my mind), but after understanding, works fine :)

You may use my script.

0.5 mbit/s was given to 192.168.0.2
3.3 mbit/s was given to 192.168.0.3

Any others had 256 kbit/s.

Code:

#!/bin/bash
shaper_start() {
tc qdisc add dev eth1 root handle 1:0 htb default 254

tc class add dev eth1 parent 1:0 classid 1:1 htb rate 0.5mbit
tc class add dev eth1 parent 1:0 classid 1:2 htb rate 3.3mbit
tc class add dev eth1 parent 1:0 classid 1:254 htb rate 256kbit

tc filter add dev eth1 protocol ip parent 1:0 prio 1 u32 match ip dst 192.168.0.2 flowid 1:1
tc filter add dev eth1 protocol ip parent 1:0 prio 1 u32 match ip dst 192.168.0.3 flowid 1:2
}

shaper_stop() {
tc qdisc del dev eth1 root
}
shaper_restart() {
shaper_stop
sleep 1
shaper_start
}

case "$1" in
'start')
  shaper_start
  ;;
'stop')
  shaper_stop
  ;;
'restart')
  shaper_restart
  ;;
*)
echo "usage $0 start|stop|restart"
esac

Hi Lexus45,

Thanks for your reply,

Its true, its not much easy to understand...

Can you explain me in deeply? I am understanding little bit in your script... but i need to understand much more...

My Office Network Setup is like Below,

We are having one lease line (ISP Provided 4Mbps Line), This direct line connected to one UN-managable switch, here we have kept 2 Squid (RHEL5) Proxy server for each floor(172.16.4.xxx & 192.168.5.xxx), Both network made routing so any client can ping each other IP's...

Now here i need to divide internet speed for each floor from main Line (from 4mbps)... planning to divide 2+2mbps or 3+1mbps for each floor...

As per my network diagram what you would suggest to implement this internet speed dividetion ??

If you're using RedHat 5 then why not contact RedHat support, that's what you're paying them for.
