[LARTC] IP based bandwith limit

[LARTC] IP based bandwith limit

[Christoph Petersen]

Hi,

i've following problem. One of our gateway router, which connects some 
of our customers should have bandwith limit.

So customer A with IP XX should have 2 Mbit, customer B with IP YY 
should have 10 Mbit. There is no need of borrowing bandwith so no 
fairness needed.

My simple question: with which technique should I manage this shaping? 
Or is there any existing project which provides this allready?

Hi!

Again, beware, that I am new to this myself, but if there is no borrowing 
necessary, does that mean you have more than 12 Mbit to hand out. If so, I 
assume you have one interface per customer, in which case you could use 
tbf on each interface. If both customers are behind the same interface you 
could use htb and lower the ceiling per customer, which has the same 
effect, with a filter rule for each customer --> class, based on ip 
address. 

Hope this helps, correct me if I am wrong.

Hi,

unfortunately there is only one interface for the customers. My problem 
is to limit the up AND down speed in dependence to each other.

So customer A get a bandwith of 2Mbit this is up AND down so if he 
downloads with 1Mbit he gets a max upload speed of 1Mbit.

I've tried it with htb like this:

#!/bin/sh
TC=/sbin/tc
DEV=eth0

$TC qdisc add dev $DEV root handle 1 htb default 90
$TC qdisc add dev $DEV handle ffff: ingress
$TC class add dev $DEV parent 1: classid 1:2 htb rate 100Mbit burst 6k

$TC class add dev $DEV parent 1:2 classid 1:10 htb rate 10kbps ceil 10kbps
$TC filter add dev $DEV parent 1:0 protocol ip prio 100 u32 \
    match ip dst 192.168.1.19 \
    classid 1:10

$TC filter add dev $DEV parent ffff: protocol ip prio 50 u32 \
    match ip src 192.168.1.19 \
    police rate 10kbps burst 10k drop flowid 1:10

this is my internal test. But it wouldn't work with dependence to each 
other...

Hi 

like I said, I am new too, so take this with a grain of salt. 

> unfortunately there is only one interface for the customers. My problem

Downloads become uploads on your internal interface!

so if eth0 is your external interface a download would be INCOMING on eth0 
but as it is going on to your internal interface (e.g. eth1) it becomes an 
upload to your customer. So incoming traffic from the internet to your 
customers is outgoing on eth1. 

if you do this on eth1: 
--------------
#!/bin/bash
tc qdisc add dev eth1 root handle 1: htb default 20
tc class add dev eth1 parent 1: classid 1:1 htb rate 90mbit burst 15k
tc class add dev eth1 parent 1:1 classid 1:10 htb rate 10mbit 
                                                      prio 0 burst 15k
tc class add dev eth1 parent 1:1 classid 1:20 htb rate 1mbit ceil 1mbit
						      burst 6k prio 1
U32="tc filter add dev eth1 protocol ip parent 1:0 prio 0 u32"
$U32 match ip dst 192.168.1.19 flowid 1:10
---------------

Then you have split the traffic into two classes: 

one for the preferred customer, who gets 10Mbit and a default for all the 
other traffic, which gets 1Mbit. It still leaves a lot of bandwidth 
unused! (79 Mbit)

I have made the experience (which cost me an awful lot of time) that 
assuming the interface woudl produce excactly 100Mbit is a mistake and htb 
does unexpected things. It is probably bets to lower the parent class 
trafic 1: to something about 10% below your actual internet connection, 
even on your internal interface. (Please correct me if I am completely 
wrong!) I used iptraf to have a look on the throughput. 


You would have to do something similar for actual uploads from your 
customers to the internet on eth0, but as you probably nat the traffic I 
am not certain what you would do there! Anyone else?

greetings, 

.peter

Hi,

okay, but I think I have some problems understanding the interaction 
between upload and download. How I have to define my traffic classes to 
match upload and download depending on each other?

That's not easy to do at all. You'd have to use the one and the same class 
to put both up- and download traffic in (both as outgoing traffic on the 
same device). Usually this can't be done. Maybe it's possible with IMQ?

Re: [LARTC] IP based bandwith limit

[Christoph Petersen]

Hi,

with htb and ingress I was been able to shape the bandwith to fit my 
wishes. But it's the same problem: I couldn't clue download and upload 
together so I was been able to shape upload to 10kbps and download too. 
But when I download some file and upload in the same time I was getting 
10kbps on each line...

Hi,

one question - whats the trick behind your marking "flags" (28, 56, ...).

[Peter Huetmannsberger]

Hi!

This is a nicely organized script, thank you. If I understand it correctly 
it stilmeans that there is a bandwidth of 28k for both upload and download 
though, and not 28k altogether. Or am I wrong?

many thanks, 

.peter

Re: [LARTC] IP based bandwith limit

[Christoph Petersen]

Hi,

some other question - with this setup there are two interfaces.
Each interface has two classes. So if I take 1:16 example I've
1.5Mbit for upload and other 1.5Mbit for download. But when I upload
with 1.5Mbit how many bandwith there is for download?
