[ns-users] Sending 'n' packets with OTcl

one way of doing that would be to attach an FTP agent to the TCP
source. the ftp source can then be controlled to send a desired
number of packets. for example

set src [new Agent/TCP/FullTcp]
set sink [new Agent/TCP/FullTcp]

$ns attach-agent $s1 $src
$ns attach-agent $k1 $sink
$ns connect $src $sink

set ftp1 [new Application/FTP]
$ftp1 attach-agent $src

$ns at 0.15 "$ftp1 produce 100"

the last line makes the ftp source send 100 packets. hope this helps.
