This section contains a pointer to an example Web Server simulation script and shows its network topology. Download "ex-web.tcl" and "dumbbell.tcl" files and examine them yourself. This example is from the 5th VINT/NS Simulator Tutorial/Workshop. Note that you should change the path for "http-mod.tcl" at the begining of the script to an appropriate one to make it run on your machine.
