I am simulating following code now.
But, drop rate fluctuates extremly one-by-one. For example,if drop rate of flow1 is 0.02 , drop rate of next flow is 0.06. i.e, former is less 3 times than later. Drop rate must appear evenly in my expectaion, but result is not. Of course, if propagation delay is changed, result(drop rate)
is changed.
Following code is a part of entire code which is attached, i think that this part may have problem. If there is anybody who have same case, and solve that problem
,tell me answer or hint.
#Create links between the nodes
for {set j 0} {$j <50} {incr j 1} {
$ns duplex-link $src($j) $r0 10Mb [expr $j*5+5]ms
DropTail
$ns duplex-link $snk($j) $r1 10Mb 10ms
DropTail
}
$ns duplex-link $r0 $r1 10Mb 20ms DropTail
