BRITE has two input interfaces: a Java based graphical interface and a command line interface. All topology generation parameters are specified in a configuration file, which can either be generated automatically by the GUI or manually created.
At present, BRITE has only a single output interface: a BRITE format topology file. Visualization output and export to simulation environments such as NS and SSF are in development.
In the following sections, we discuss the input interfaces of BRITE: the graphical interface, the command line interface and finally the BRITE configuration file format. Next, we describe the output interface of BRITE: the BRITE topology file format.
