'''Limit Different Bandwidth In Day and Night.'''

There was an example earlier, about different bandwidth allowed for users at different times.

Let's say you have corporate users / institutions / government. People that arrive at 07.00 and leave the office 18.00 at most. You reserve them 1 mbit/s all the time. Most of your home users are using maximum bandwidth after 15.00 and up to 01.00 hours. 
So, you decide you may "lend" some of the bandwidth of the users that are not working, while they are not...
How ?

You can of course add 2 ( two ) queues for each limit you want to put, but you can also put a single queue, and modify it's limits from a script. Might just be simpler. Why ? You keep the limits for different type of users in a single place.

Ok. Now, for this to work, first of all sync your clock. Or you might get strange results and complains. :)

1. Premises:
You are using simple queues to limit the traffic. 

( This can be easily adapted to queue tree, by modifying limits in the queue tree.... but that's another story. Work it out yourself.)

You have 3 types of users:

- 256k/256k at day, 1M/1M at night

- 512k/512k at day, 2M/2M at night

- 1M/1M at day, 4M/4M at night

You limit them by individual simple queues, and distinction among categories is by comment. ( i put this also on queue name to make it easier to see. It seems to me that winbox does not display comments on v3.6 at least on the RB I am working with right now :(, but the console uses them right and the scripts work fine )

'''How do we do it?'''

- Put simple queues with established limits, and distinctive queue ''_comment_'' for each category of users. ( eg. ""Vasile_CAT1"", ""Vasile2_CAT2"", etc as queue names, and [CAT1, CAT2 will be the category identifiers, put in comment]

- Establish limits for each category: CAT1, CAT2, etc., we will modify this from the 2 scripts that handle everything.

- Put the script to run from the scheduler every 24 hours, and modify limits for day/night, reg. each category of users. The script for the "day" starts 06.00 hours, and ends 18.00 hours, when the script for the "night" starts, enabling the ''night'' modifications.

== Setup NTP Client ==

If this is not done and your clock is out of sync, you might get strange results.

<pre>
/system ntp client 
set enabled=yes mode=unicast primary-ntp=213.239.154.12 secondary-ntp=213.249.66.35 
</pre>
( You can put primary-ntp and secondary-npt to be resolved to whatever 0.europe.pool.ntp.org and 1.europe.pool.ntp.org is pointing to. Please replace "europe" with your continent, for further improvement on response times and proximity. See ntp.org for further information )


Setup four queues ( for this example only. you can setup as many as you like, it does not matter )

<pre>
/queue simple 
add comment="CAT1" direction=both disabled=no dst-address=192.168.4.15/32 \
    max-limit=256000/256000 name="George_CAT1" parent=none priority=8 \
    queue=default-small/default-small
add comment="CAT1" direction=both disabled=no dst-address=192.168.4.16/32 \
    max-limit=256000/256000 name="Robinson_CAT1" parent=none priority=8 \
    queue=default-small/default-small
add comment="CAT2" direction=both disabled=no dst-address=192.168.4.17/32 \
    max-limit=512000/512000 name="Crusoe_CAT2" parent=none priority=8 \
    queue=default-small/default-small
add comment="CAT3" direction=both disabled=no dst-address=192.168.4.18/32 \
    max-limit=1024000/1024000 name="Momma_CAT3" parent=none priority=8 \
    queue=default-small/default-small

</pre>


Now, these were the queues. Let's see:

== The scripts ==

For the "day" limits:
<pre>
/system scheduler 
add comment="" disabled=no interval=1d name="Day" on-event="/queue simple\r\nset [find \
    comment=CAT1] max-limit=256000/256000\r\nset [find comment=CAT2] \
    max-limit=512000/512000\r\nset [find comment=CAT3] max-limit=1024000/1024000\r\n" \
    start-date=jan/01/1970 start-time=06:00:00 
</pre>


For the "night" limits:
<pre>
/system scheduler 
add comment="" disabled=no interval=1d name="Night" on-event="/queue simple\r\nset [find \
    comment=CAT1] max-limit=1024000/1024000\r\nset [find comment=CAT2] \
    max-limit=2048000/2048000\r\nset [find comment=CAT3] max-limit=4096000/4096000\r\n" \
    start-date=jan/01/1970 start-time=18:00:00 
</pre>

Well, in clear text, they look like this:

<pre>
'''DAY:'''

/queue simple
set [find comment=CAT1] max-limit=256000/256000
set [find comment=CAT2] max-limit=512000/512000
set [find comment=CAT3] max-limit=1024000/1024000


'''NIGHT:'''

/queue simple
set [find comment=CAT1] max-limit=1024000/1024000
set [find comment=CAT2] max-limit=2048000/2048000
set [find comment=CAT3] max-limit=4096000/4096000
