Tracing link dynamics.

[rrao <rrao@cs.ua.edu>]

Hi,
        I tried using network dynamics capabilities of ns for unicasting
using DV.
I set up an  rtModel  DV  using ::

            set rtmodel1 [$ns rtmodel Exponential $node_(s1)
$node_(r1)]
& then used  ::

            $rtmodel1 trace-dynamics $fh1

to try & generate the trace for the link
I get the following error ::

_o28: unable to dispatch method trace-dynamics
    while executing
"$rtmodel1 trace-dynamics $fh1"
    (file "test3.ns" line 22)

If any of you all knows what is to be done to rectify this, please tell
me.

Thank's ,

Ranganath
