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=1
set udp1 [new Agent/UDP]
$ns_ attach-agent $node_(1) $udp1
$udp1 set class_ 1
$udp1 set fid_ 1
set 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 3
set null1 [new Agent/Null]
$ns_ attach-agent $node_(8) $null1
# Connect the CBR generator to the loss monitor
$ns_ connect $udp1 $null1
Cheers,
Mohammed AbuHajar

Subject: [ns] Traffic generation in a proc
Hi every one,
I wrote a tcl proc for the generation of a cbr trafic :
proc generate_cbr_traffic {agent_src size rate start_time end_time} {
global ns puts "In generate cbr: $agent_src $size $rate $start_time
$end_time" set cbr_ [new Application/Traffic/CBR] $cbr_ set type_ CBR $cbr_ set
packetsize_ $size $cbr_ set rate_ $rate $cbr_ attach-agent $agent_src $ns at
$start_time "$cbr_ start" $ns at $end_time "$cbr_ stop"}
I made the connection of the udp agents outside the procedure , when I call the
procedure, in the NAM environment no traffic was generated ,
Thanks for your help
nabila
