Create two simple queues for the same network with different Bandwidth Limit.

Limit Different Bandwidth In Day and Night.
There are lot many ways to limit bandwidth for day and Night, but personally I found this is the easiest way, Here it is.
I have used Simple Queue, Script and Scheduler.
Suppose we have one network 192.168.1.0/24 and want to limit Bandwidth for day and Night Time.

Network 192.168.1.0/24
Bandwidth = 06:00am – 18:00pm – 1Mbps. <Max-Limit>
Bandwidth = 18:00pm – 06:00am – 2Mbps. <Max-Limit>

Create two simple queues for the same network with different Bandwidth Limit.

/queue simple
#name=”Day” target-addresses=192.168.1.0/24 dst-address=0.0.0.0/0
interface=<ether-x> parent=none direction=both priority=8 
queue=default-small/default-small limit-at=512k/512k 
max-limit=1M/1M total-queue=default-small

#name=”Night” target-addresses=192.168.1.0/24 dst-address=0.0.0.0/0
interface=<ether-x> parent=none direction=both priority=8
queue=default-small/default-small limit-at=1M/1M 
max-limit=2M/2M total-queue=default-small

Now, write scripts

/system script
#name=”Day” source=/queue simple enable Day; /queue simple disable Night

#name=”Night” source=/queue simple enable Night; /queue simple disable Day

Finally, Schedule it

/system scheduler
#name=”Day” on-event=Day policy=read,write start-date=oct/13/2007 start-time=06:00:00 interval=1d

#name=”Night” on-event=Night policy=read,write start-date=oct/13/2007 start-time=18:00:00 interval=1d
