That's right, And that's why I tried to find something else to
match Real-Time packets, but it seems like there is no standard for
that. Am I wrong ? If so, could you please tell me How to do!!!
But with RTP, it's a beginning because I match with H.323 protocol,
which carries Real-Time...
RTP means Real Time Protocol isn't it?
So why using another protocol??
I'd like to find smthg in IP header that matches *ALL* real-time packets.
Is there a standarisation ?
I looked in precedence bits in TOS field, something which could help,
but I'm not sure that the value is set for all real-time multimedia packets.
[NO STANDARD FOUND]
Packets carried by RSVP or not, RTP or not, and all others which contain
real-time data.
Could I assume that TOS precedence bits value for Real-Time packets
is higher than 4?? That's the only way I have from now.
Concerning IPv6, have the class field a specific value for that?
In that case, where can I find info on the differnet values of this class field??
Thx
Seb.
