[LARTC] Help with prioritizing internet Cafe Terminals

[Craig Main]

Hi All,

I am new to tc so please forgive me. I have read as much documentation
as I can get my hands on, but I still have problems with getting the
rules right. Here is my scenario:

Internet Cafe/Office

4 Internet Cafe Terminals
3 Office Terminals

Leased Line connectivity at 64Kbps.

What I would like to have:

All Cafe terminals have priority to the internet over the office
machines. Each cafe terminal must not be able to have all the
bandwidth if other cafe terminals are online. If all cafe terminals
are online at once, the bandwidth must be shared evenly amongst them.
All Office Terminals must have the lease priority.

I hope this makes sense.

I anyone in a position to help me here?

TIA

Craig

My Fair NAT script [1] comes very close to that. It can share available 
bandwidth evenly among your machines; however, it can't give your cafe a 
higher priority than your office. A workaround for that might be to put 
all office machines together in a group, so all of them together would get 
the same priority and bandwidth as a single cafe terminal.

If the script isn't suitable for your network, it may serve as an example. 
At least the documentation or the class graphics should give you some idea 
how to create your own shaping setup.

I have out together the following script, can those in the know please
comment on what I have done and whether it will achieve what I am
looking for. Many thanks.


#!/bin/bash

tc qdisc del dev eth1 root

tc qdisc add dev eth1 root handle 1: htb default 12

tc class add dev eth1 parent 1: classid 1:1 htb rate 64kbit ceil
64kbit burst 20k

tc class add dev eth1 parent 1: classid 1:2 htb rate 15kbit ceil
64kbit prio 0 burst 20k
tc class add dev eth1 parent 1: classid 1:3 htb rate 15kbit ceil
64kbit prio 0 burst 20k
tc class add dev eth1 parent 1: classid 1:4 htb rate 15kbit ceil
64kbit prio 0 burst 20k
tc class add dev eth1 parent 1: classid 1:5 htb rate 15kbit ceil
64kbit prio 0 burst 20k

tc class add dev eth1 parent 1: classid 1:12 htb rate 4kbit ceil 64kbit prio 1

tc filter add dev eth1 protocol ip parent 1: prio 1 handle 1 fw classid 1:2
tc filter add dev eth1 protocol ip parent 1: prio 1 handle 2 fw classid 1:3
tc filter add dev eth1 protocol ip parent 1: prio 1 handle 3 fw classid 1:4
tc filter add dev eth1 protocol ip parent 1: prio 1 handle 4 fw classid 1:5

You are giving all your addresses the same MARK?  I don't think that's what 
you want.

That was a typo on my part...I am more interested in the actual tc
commands and setups. Will they do what I want?

Thanks
