In this paper, the authors study the properties of Protocol Independent Multicast (PIM) in non-strictly hierarchical network environments. In particular, they investigate the cost (overhead) behavior of the PIM protocols i.e., Sparse Mode (PIM-SM), Dense Mode with Flood and Prune mechanism (PIM-DMFP), Dense Mode with State Refresh (PIM-DMSR) and Source Specific Multicast (PIM-SSM). By assuming that the links in the networks are symmetrical, they assign equal values to both up and down links and then specify analytical models to evaluate the performance of the protocols in static multicast group scenarios.
