[mpls-linux-general] R: Re: MPLS and 802.11e

[<luc...@li...>]

I use iwpriv, available with the madwifi driver.
It is not made for MPLS, but 
I wonder if I can use it or something similar to implement QoS at both layers.

My intention was to use 802.11e + some traffic engineering in MPLS.
Can you 
give me some advice about it?
Thank you

Hello

How 
do you map the DSCP to the wireless class? Which tool do you use for this? It 
might be that the tool/module you're using expects IP traffic, not MPLS...

Hello, I'm still working with MPLS over WiFi.
I'm trying to enable 
wireless QoS
extensions (802.11e) together with MPLS, but it seems not to 
succeed in
classifying the flows once they are encapsulated in MPLS.
I try to 
explain:
802.11e does a matching between the DSCP field of IP header and a 
class (Access
Category) .
When I send a flow with MPLS, if I sniff the traffic 
with wireshark
I can see the DSCP field correctly written, but the wireless QoS 
information do
not match with the right class.
Otherwise, if I send the same 
flow without
MPLS, everything works fine.
I'd like to understand why, can 
anybody help me?

Thanks a lot,
Luca
