Dear All
I am having this error while trying to run monitor-queue
can't read "link_(5:6)": no such variable
while executing
"$link_([$n1 id]:[$n2 id]) init-monitor $self $qtrace $sampleInterval"
(procedure "_o3" line 3)
(Simulator monitor-queue line 3)
invoked from within
"$ns_ monitor-queue $n0 $n1 stdout"
invoked from within
"set qmon [$ns_ monitor-queue $n0 $n1 stdout]"
(file "ranWless.tcl" line 165)
this tcl script is
set queue [open queue w]
set qmon [$ns_ monitor-queue $n0 $n1 stdout];
[$ns_ link $n0 $n1] queue-sample-timeout;
proc queueLength {} {
global ns_ qmon queue
set time 0.05
set length [$qmon set pkts_]
set now [$ns_ now]
puts $queue "$now $length"
$ns_ at [expr $now+$time] "queueLength"
}
$ns_ at 0.0 "queueLength"
