Hello Sir,

I am using your multi interface script in that how to modify the script to see two simultaneous transmission from a node as they have two interfaces in two different channel I want the node to start the transmission at the same time to the two different destination nodes is that possible ? IF yes please let me know how to accomplish it.

I am doing like this

set tcp [new Agent/TCP]
$tcp set class_ 2
set sink [new Agent/TCPSink]
$ns_ attach-agent $node_(0) $tcp
$ns_ attach-agent $node_(4) $sink

$ns_ attach-agent $node_(0) $tcp
$ns_ attach-agent $node_(3) $sink
$ns_ connect $tcp $sink
set ftp [new Application/FTP]
$ftp attach-agent $tcp
$ns_ at 50.0 "$ftp start"

But I see only the last pair in the trace file.I am wondering why the transmission from 0 to 4 is not seen.

Waiting for your response

Sena

@Sena - You need to configure 2 TCP flows - tcp0 and tcp1 and attach FTP on each of them. Start both the flows at the same time. You will be able to see simultaneous transmission of packets.

Hope it helps.

please help me ....it is very important for my masters project

@Shiva - Make sure you have assigned the channels properly to all the nodes. There must be atleast one common channel between nodes to communicate.

Hope it helps.

Pls advice.
