Hi, If I really understand your problem, you need to the random size for each packet but using CBR traffic model? Why not modify the CBR application c++ code and modify the variable size_ ( which is usually have its value from bind with tcl script ). So in the function which sends the packet you can modify the variable size_ before send the packet...It shall work I think... I don't know whether it is that you want in your simulation.
