[Serusers] QoS with rtp

[Lucas Aimaretto]

Hi all,

I've used for long time the QoS capabilities of linux for
shaping/prioritizing traffic. Now, i'm willing to prioritize rtp packets
in my lan, over the rest ot packets. I've used the u32 filters, but I
did not really found a nice way of "matching" a rtp packet. I read the
rfc so as to look at the rtp-header and found that the only field wich
does not change its value along time is the version-field. It is located
at the 29th byte ( with byte 0 at the IP heder first byte ). But it is a
really poor way of doing it, because there may be many other packets
wich will "get caugth" by this rule ...

any ideas ? any experience in the subject ...

Regards,

Lucas
