Whilst working through labs for the BSCI CCNP exam (using the fantastic Dynagen / Dynamips) I came across the need for a multicast traffic generator. Googling showed me there was “MINT” but further investigation showed it didn’t do Windows, a little more faffing about with hping, nemesis and bittwist got me no closer.
Then I found a link which solved all my problems. I have the Windows Resource Kit and it does multicast generation. Magic.
