Re: [ns] multiple path links?
Dear Lloyd,
Thanks for u quick response.But
i think there was some misunderstanding with my question.I just need to
many links which can form a Optic fiber with diffrent wavelength ,where each
link has a different bandwidth.
and so i tried to have 2 simplexlinks between n1 and n2
like in Example3.tcl->
#create 4 nodes using arrays
for {set i 0} {$i < 4} {incr i} {
set n($i) [$ns node]
}
$ns duplex-link $n($i) $n([expr ($i+1)%4]) 1Mb 10ms DropTail
$ns duplex-link $n($i) $n([expr ($i+1)%4]) 2Mb 10ms DropTail
################################################################
but i couldnt trace the o/p properly
i could see the bandwith getting overlaped.
what i try here is to have WDM_LINK between these two nodes,by using the tcl.
May be my appraoch and my understanding is wrong on this.
Do i need to code in c++ to get a wdm_link or is that enough if i could
inherit link.tcl to acheive this.
Hope i had explained in a better way this time
thanks
Kishore
