I have another idea, try to use a traffic scenario generator tools
"cbrgen.tcl." that is located in the "~/ns-2.28/indep-utils/cmu-scen-gen" to
generate your CBR traffic in a separte file. and link your file within your TCL
scipt. I think this is a good technique, I used it befor. Beside that you can
use AWK or Perl or bash scripts for extracting results form the simulated
output file. So If want to want to test this way I will privide you some
scripts and I will assist you.
About proc I think there is some statement should written in you procedure
block.. let me search about that.
Regards.

just to your knowledge, no problem arises for the exponnential traffic, the
procedure works perfectly, can a cbr traffic simulated by a an exponential
with 0 for idle time?
Thanks for help
