Re: [ns] Re: RE: simulating CSMA/CD
Hi,
Collisions are not indicated in nam output. Since trace files in ns
usually record transport level functionality like drops etc.
Collisions occur at the MAC layer. The current snapshot has support for
collision recording along with an example(in the
~ns/tcl/test/test-suites-lan.tcl ) of how to use it.
The xgraph manpage has an example of how to use it.
i hope this helps.

(1) how to generate traffic with distribution of poisson process;
(2) how to show the collision clearly by using "nam"
(3) i think the curv will be drawed by xgraph,but i don't know how to generating such files used by xgraph.
