[LARTC] In & out traffic

[LARTC] In & out traffic

[Ali badilli]

Hi all,

 I have the following test-bed.

  A-----B-----C

Router A,B, and C. Router A has eth0, B has eth0 and
eth1, and C has eth0.

I can apply TC functions in B (eth0) for traffic
coming from A, for example limit the link BW to 5Mb
and divide among multiple clasess. Now, I want to the
same thing for traffic coming from C and going to A. I
can have similar action for traffic coming from C in
eth1. However, it seems the link capacity allocated in
eth0 is only for incoming traffic (from A), how can I
specify link capacity for incoming and outgoing
traffic separately.   

In Howto document it seems, all the examples for the
traffic for outgoing from one interface, Is tehre any
way to divide the link for incoming and outgoing
traffic, and apply tc function separately.

Thanks in advance
Haci

Hello, yes this is possible, this is called "ingress policy".

Take a look at the lartc doc, at the end there is somo cookbook examples.
I had it working. You can limit the incoming traffic "killing" some
packets.

Very recently on the list was also published the new IMQ device, which can
do advanced traffic shapping over incoming traffic.

On the other hand, I don't know if in case of semi-duplex mediums, where
the real bandwidth is shared between reception and transmition, it is
possible to limit this real bandwidth (transmit bandwidth dependent of
receive bandwidth). Maybe IMQ is also the solution, I don't know.
