Dear Rossy,

D-ITG has some built-in models for VoIP traffic over RTP.
This means that if you issue:

./ITGSend -a some_receiver_host VoIP -x G711.1 -h RTP

ITGSend will generate UDP packets with size and inter departure time 
that mimic those of a VoIP flow using RTP protocol and G.711 codec. 
Clearly, in such packets there will be no RTP header neither voice 
content, but the size and the inter packet time will be, at least, similar.

For video traffic, you could use some well known models such as that 
presented in "Analysis, modeling and generation of self-similar VBR 
video traffic" from Mark W. Garrett and Walter Willinger, and instruct 
ITGSend to generate UDP packets using the related packet size and inter 
packet time models.

Best regards.

AB
