$ns_ cancel Cancels the event. In effect, event is removed from scheduler’s list ofready to run events.$ns_ create-trace This creates a trace-object of type between and objectsand attaches trace-object to for writing trace-outputs. If op is definedas "nam", this creates nam tracefiles; otherwise if op is not defined, nstracefiles are created on default.$ns_flush-traceFlushes all trace object write buffers.$ns_ gen-mapThis dumps information like nodes, node components, links etc created for agiven simulation. This may be broken for some scenarios (like wireless).$ns_ at-now This is in effect like command "$ns_ at $now $args". Note that this functionmay not work because of tcl’s string number resolution.These are additional simulator (internal) helper functions (normally usedfor developing/changing the ns core code) :$ns_ use-scheduler Used to specify the type of scheduler to be used for simulation. The differenttypes of scheduler available are List, Calendar, Heap and RealTime. CurrentlyCalendar is used as default.$ns_ after Scheduling an to be executed after the lapse of time .$ns_ clearMemTraceUsed for memory debugging purposes.$ns_ is-startedThis returns true if simulator has started to run and false if not.43
$ns_ dumpqCommand for dumping events queued in scheduler while scheduler is halted.$ns_ create_packetformatThis sets up simulator’s packet format.44
