[LARTC] Prioritizing UDP Packets?

[LARTC] Prioritizing UDP Packets?

[Sommarnatt]

Greetings,
I'm new to LARTC and I'm trying to solve a problem with multiple clients 
accessing a game server. So I thought I'd give traffic control a shot.

I've downloaded Wonder Shaper and have added this to the default script:

tc filter add dev $DEV parent 1:0 protocol ip prio 12 u32 \
   match ip protocol 0x6 0xff flowid 1:3

I'm now quite sure about everything in the script - all I want is to prioritize 
the UDP traffic, so that it always gets sent and recieved.
What should I remove / add?

Any help is appreciated!

Thank you.

Kind Regards,
Sommarnatt

There is no flowid 1:3 in the default script. was that supposed to be 1:30 ?

The above rule matches tcp traffic and puts it in the low priority queue (if you used 
1:30).
I guess this would therefore make UDP faster.
you might also want to try putting UDP in flow 1:10

This won't affect download UDP traffic though, the wondershaper
only shapes outbound (sent) traffic, and polices inbound (received) traffic.
If you want to prioritize downloaded UDP traffic, you'll need to use 2 network 
interfaces, or play around with the IMQ device.
(or one of the other suggestions that have been discussed recently)

Yes it seems I didn't copy it right. Changed it to 1:10.

Alright. I'll have to read the howto on this, haven't had the time yet :/

Thanks for your help!
