[ns] cbr broadcast in ns-2

[Jerome Haerri]

Hi ns users,

I would like to know how we could generate a packet broacasting scenario
in ns-2 similar to cbr_gen.tcl but for broadcast packet. For example,
how could we generate broacast packets and vary the rate, or size of the
packets ?
Does a broadcast agent exists (similar to the cbr agent but for broacast ?)

Thanks for your help

Jerome
