FYI:
There is a Inet to ns topology convertor available at
http://www.isi.edu/nsnam/ns/ns-topogen.html
Instructions:
Usage: inet2ns < inet.topo > ns.topo
In ns:
source ns.topo in your tcl script and call the procedure to create the
topology using
create-topology linkbw [scaling factor for delay]
Thank you
