41.3.1 An example

The following code illustrates the basic steps to configure an Exponential traffic source over a UDP agent, for traffic flowing from node s1 to node k1:

        set src [new Agent/UDP]
        set sink [new Agent/UDP]
        $ns_ attach-agent $node_(s1) $src
        $ns_ attach-agent $node_(k1) $sink
        $ns_ connect $src $sink
	
        set e [new Application/Traffic/Exponential]
        $e attach-agent $src
        $e set packetSize_ 210
        $e set burst_time_ 500ms
        $e set idle_time_ 500ms
        $e set rate_ 100k

        $ns_ at 0.0 "$e start"
