[LARTC] Shaping

[LARTC] Shaping

[Isak Badenhorst]

Hi all

I am trying to shape the e-mail going out on my network.  When i send some 
outgoing mail it just eats up all bandwidth available.  I would appreciate 
some help.  I have a 128kbit link to my provider.


tc qdisc add dev eth0 root handle 10: cbq bandwidth 10mbit avpkt 1000
tc class add dev eth0 parent 10:0 classid 10:2 cbq bandwidth 10mbit rate 
128kbit allot 1514 maxburst 20 avpkt 1000 isolated bounded prio 3
tc qdisc add dev eth0 parent 10:2 handle 20: cbq bandwidth 128kbit allot 
1514 avpkt 1000
tc class add dev eth0 parent 20: classid 20:10 cbq bandwidth 128kbit rate 
16kbit weight 4 allot 1514 maxburst 20 avpkt 1000
tc class add dev eth0 parent 20: classid 20:20 cbq bandwidth 128kbit rate 
112kbit weight 12 allot 1514 maxburst 20 avpkt 1000

tc filter add dev eth0 parent 10: protocol ip prio 3 u32 match ip src 
0.0.0.0/32 flowid 10:2
tc filter add dev eth0 parent 20: protocol ip prio 3 u32 match ip dport 25 
0xffff flowid 20:10
tc filter add dev eth0 parent 20: protocol ip prio 3 u32 match ip src 
0.0.0.0/32 flowid 20:20

Any help would be appreciated.

Thanks

Isak

I suppose the setup is not working ?   :)
Change 128kbit in 120kbit.  Rule 1 for shaping : "Make sure YOU are the 
bottleneck".

[LARTC] shaping

[Abraham van der Merwe]

Hi!

Is there any way to do just plain vanilla TBF (Token Buck Filter) type
shaping on a group of ips/networks, not an entire interface.

Currently the only way I know how to shape in Linux is to use HTB or CBQ,
but both of these need a total rate and then you need to subdivide that
into classes. That is not what I want. All I want is Cisco generic traffic
shaping style shaping (or similar to how the old shaper module worked), iow
I don't want to specify how much bandwidth I have, I just want to make sure
that any particular group never exceeds a given rate.

Not the answer you're looking for, but why not just specify your total
bandwidth being much larger than your interface actually is and then
subdividing into your groups?

Hi Mike                                          >@2004.05.31_15:17:21_+0200

I have thought of that, but that is not ideal for a couple of reasons, the
two most important being:

 (a) You can't add 1 leaf node at a time with HTB or CBQ which makes it
     rather messy to add large numbers of rules.

 (b) I'm not sure what HTB will do if you lie about the total rate. We have
     tried this on various occassions and in all cases HTB just didn't work
     if you did this - not even the guaranteed rates worked properly.
