If not, it is an "invisible" header, put there just for informational purposes and not affecting the simulation outcome. bye, Marco >---- Messaggio originale---- >Da: [EMAIL PROTECTED] >Data: 4-apr- 2007 4.37 PM >A: <ns-users@ISI.EDU> >Ogg: [ns] why RTP header in UDP's sendmsg() ? > > >Hiya, > >I'm not sure if this issue rather belongs to the dev-mailinglist instead >of the users' one but since it's just a question and not some sort of >contribution I'll try here first: > >I've looked at the UDP code (in apps/udp.cc) and came to realize that >everytime the sendmsg() function is called a RTP header is put on top of >the packet, including (talk burst) flags, sequence number, and a time >stamp. > >Just wondering: What's the rationale behind this? > > >Cheers, > >--Timo > >
