[ns] Traffic generation in a proc

[Nabila khedimi]

Hi, 
I am still wondering about the no generation of a trafic when it is done by a procedure  although the same code made outside works, but when I put it in a procedure it does not!!!  anyone has an idea

Hi ns user,
Try to wirte the cbr traffic without procedure to show it is correct or not. Like
 
# Traffic Source 1: Mobile node1->node3, flowid=1set udp1 [new Agent/UDP]$ns_ attach-agent $node_(1) $udp1$udp1 set class_ 1$udp1 set fid_ 1set cbr1 [new Application/Traffic/CBR]$cbr1 attach-agent $udp1$cbr1 set rate_ 20kb$cbr1 set packetSize_ 512#$cbr1 set interval_ 0.2
# Set loss monitor (to count bytes) at node 3set null1 [new Agent/Null]$ns_ attach-agent $node_(8) $null1
# Connect the CBR generator to the loss monitor$ns_ connect $udp1 $null1
 
 
Cheers,
