Re: [ns] Urgent - Reg node id!!

the third and the fourth field are the source and
the destination (precisely the two nodes) between
which the packet is currently flowing through.

If you are only interested in identifying the two
nodes through which the packet is currently between
in c++, you can always get the values of the
src_ and the dst_ which are the Trace class variables
and are set when the Tracing between these two nodes
are enabled (in the create-trace subroutine).  To
find out how Trace stores these two, look at
create-trace routine in ns-lib.tcl.
