Dear ns users, please I need your HELP. I have the simulation multicast model, where is only one source (I'm using Seesion/RTP) a number of receivers (Session RTP also). Session/RTP class create one Agent/CBR/RTP (called dchan_) and one Agent/RTCP (called cchan_). Is the part of my script correct?
_______________________________________ # src_ send packets to the multicast group G1 set n(1) [$ns node] set src_ [new Session/RTP] $src_ session_bw 500kb/s $src_ attach-node $n(1) $ns at 0.0 "$src_ join-group $G1" $ns at 0.0 "$src_ start" #rcvr_ - I need that it will be only RECEIVE packet and in the calculated interval sends feedback by RTCP set n(2) [$ns node] set rcvr_ [new Session/RTP] $rcvr_ session_bw 500kb/s $src_ attach-node $n(2) $ns at 0.1 "$rcvr_ join-group $G1" $ns at 0.1 "$rcvr_ start" #### no "transmit" command Do you have anybody experience with the RTCP? The response interval (rint_) is calculated correct only if the rcvr_ "transmit" some data to the G1, but if I don't use the "transmit" command (rcvr_ transmit 100kb/s i.e.), the rint_ calculation give the wrong values. Please help me find a solution for this issue. THANKS THANKS THANKS. .............. THANKS.
