pimdd is a stand-alone PIM-DM multicast routing daemon available under the BSD license. This is the restored original from University of Oregon, by Kurt Windisch. pimdd is a PIM Dense Mode (PIM-DM) implementation based on pimd, which is the PIM Sparse Mode (PIM-SM) reference implementation, by Ahmed Helmy, Rusty Eddy and Pavlin Ivanov Radoslavov.
PIM-DM is a significantly less complex protocol than PIM-SM. PIM-DM works on the principle that it is probable that any given multicast stream will have at least one downstream listener. PIM-DM is ideal where many hosts subscribe to receive multicast packets, so most of the PIM Routers receive and forward all multicast packets.
