hi everyone, i set a bidirectional cbr application traffic between two nodes n0 and n19 this way:
set udp0 [new Agent/UDP] set sink19 [new Agent/Null] $ns_ attach-agent $node_(0) $udp0 $ns_ attach-agent $node_(19) $sink19 $ns_ connect $udp0 $sink19 set cbr0 [new Application/Traffic/CBR] $cbr0 set packetSize_ 260 $cbr0 set interval_ 0.020 $cbr0 attach-agent $udp0 $ns_ at 0.3 "$cbr0 start" set udp19 [new Agent/UDP] set sink0 [new Agent/Null] $ns_ attach-agent $node_(19) $udp19 $ns_ attach-agent $node_(0) $sink0 $ns_ connect $udp19 $sink0 set cbr19 [new Application/Traffic/CBR] $cbr19 set packetSize_ 260 $cbr19 set interval_ 0.020 $cbr19 attach-agent $udp19 $ns_ at 1.0 "$cbr19 start" I get a segmentation fault which disappear when increasing interval to 20 seconds for example 1- is this the correct way to set such traffic 2- what can be the cause of the segmentation fault thank you,
