Tami,
For your question my answer is
1. yes u got it, i forget to put s instead i put number thanks
2. yes we can do
The topology
n1 --- n2 --- n3 --- n4 --- n5
set requiredNodes 5
for {set i 0} {$i < $requiredNodes} {incr i} {
set n$i [$ns node]
if {$i == [expr $requiredNodex - 1]} {
$ns duplex-line $n[expr $i - 1] $ns$i 5Mb 2ms Drop Tail
} else {
$ns duplex-line $n$i $ns[expr $i+1] 5Mb 2ms Drop Tail
set tcp [new Agent/TCP]
$tcp set class_ 1
$ns attach-agent $n$i $tcp
set sink [new Agent/TCPSink]
$ns attach-agent $n[expr $i+1] $sink
}
}
I didn't test the script, i generally wrote this one, please test it and let
me know status of this,
if you want specify specific bandwidth between the nodes, you manually
stored in a list
suppose *set bandwidth [ 2Mb, 3Mb, 4Mb, 5Mb, 0.2Mb] by using list index* we
can get the bandwidth
similarly what ever you need (specifically) that stored in a list and use
them
