Re: [ns] delay command in NS
You can use the "done" call back for the TCP agent,
and schedule a future event at that time. For example:
Agent/TCP instproc done {} {
set ns [Simulator instance]
$ns at [expr [$ns now]+30.0] "$self send 20000"
}
By the way, the FTP session is not necessary if you are only sending
information
in this fashion.
