Re: [ns] collect data only between two node?

[bsikdar@networks.ecse.rpi.edu]

hi,
   suppose you want to trace the dynamics between nodes n(0) and n(1)
only in your topology. then you can add the following to your tcl code
(after the declerations for the nodes and link to be set up)

set ef [open enqueue.tr w]
set lnk [$ns link $n(0) $n(1)]
set etr [$ns create-trace Enque $ef $n(0) $n(1)]
$lnk add-to-head $etr

of course this will just trace the enqueue operations. but you can add
similar lines for the drops etc. hope this helps,
