[ns] using rtmodel-at from a function
Hi,
maybe someone can fill me in on the following:
when I manually disable and enable links using: '$ns rtmodel-at 0.1 down
$n1 $n2'
the link between n1 and n2 goes down at time 0.1.
when I include the above command in a function such as:
proc disable-link { n1 n2 }{
global ns n1 n2 ;# ns and the 2 nodes are available
$ns rtmodel-at 0.1 down $n1 $n2
}
and call this function like:
$ns at 0.05 "disable link $n1 $n2"
the link does not go down.
It doesn't have anything to do with back-in-time scheduling (as you can
see). When I look at
the file 'tcl/rtglib/dynamics.tcl' and trace the methods that are
called when 'Simulator rtmodel-at' is called I find that in de 2nd case,
'rtModel set-event-exact .. ' is not called and thus the 'link down'
event is not scheduled..
Does anybody know why this does not happen and how I can solve it. I
really need to call the 'Simulator rtmodel-at ...' method from any place
other then the 'top-level' in the simulation script.
